Cooling ownership and M&A timeline

What you can answer with it

• Check whether two shortlisted suppliers are now the same company.
• See which specialists have been absorbed by thermal or electrical majors, and when.
• Read a supplier's independence claim against its ownership record.

How the rows were built

1. Transaction rows come from the intelligence records categorised as M&A, each with its own sources and date of publication.
2. Ownership rows are the current-state field on a company record, dated to that record's last review rather than to the transaction.
3. A company whose ownership this database has not established is absent rather than listed as independent, because those are different claims.
4. Former names are kept as aliases on the company record, so a search for the old name finds the current one.

The full editorial standard, including how sources are ranked and how project stages are labelled, is on the methodology page.

  • Smardt Chiller Group description: Smardt designs several types of chiller. They include air-cooled, water-cooled, evaporatively cooled, and modular units. The designs use oil-free centrifugal compressors. Its Core and Ultra water-cooled ranges span 45 to 3,600 refrigeration tons. Layouts with several compressors can stage capacity. They can also provide some compressor-level backup. Smardt can engineer the chiller package. Pumps, towers, dry coolers, controls, and rack-side gear still need a full plant design. Buyers should get a project selection at the required water temperatures. They should also request an annual load study and a refrigerant plan. The bid should cover service, restart behavior, and witnessed tests. Range limits alone are not enough. Qualification should separate compressor backup from whole-chiller backup. It should also separate both from plant backup. Operation after one compressor stops does not prove capacity after other faults. A vessel, power feed, controller, pump, or condenser-water path can still fail. Public range pages do not give delivered price or lead time. They also omit fleet failure rates and one standard efficiency for all builds. Tender documents should name the exact model and rating standard. They should state the air and water design points and fouling basis. They should also define the part-load sequence, allowed downtime, spare-parts promise, and owner of plant controls. → Smardt designs air-cooled, water-cooled, evaporatively cooled, and modular chillers with oil-free centrifugal compressors. Its Core and Ultra water-cooled ranges span 45 to 3,600 refrigeration tons. Multi-compressor layouts can stage capacity and may provide some compressor-level backup. Smardt can engineer the chiller package, but pumps, towers, dry coolers, controls, and rack-side equipment still require a complete plant design. A useful proposal starts with a project selection at the required water temperatures, an annual load study, and a refrigerant plan. Service coverage, restart behavior, and witnessed tests also belong in the bid. Published range limits alone cannot establish suitability. Qualification has to distinguish compressor backup from whole-chiller backup and plant backup. Continued operation after one compressor stops says nothing about a failed vessel, power feed, controller, pump, or condenser-water path. Smardt does not publish delivered price, lead time, fleet failure rates, or a single efficiency that applies to every build. Tender documents need the exact model, rating standard, air and water design points, and fouling basis. They also need the part-load sequence, allowed downtime, spare-parts commitment, and ownership of plant controls.
  • Baltimore Aircoil Company description: Baltimore Aircoil Company, commonly called BAC, makes outdoor heat-rejection gear. It does not make the liquid loop inside the server. Its data-center range includes the TrilliumSeries dry cooler and the HXV hybrid cooler. These products let a plant designer trade space, fan energy, and peak water use against outlet temperature. BAC reports operating since 1938. It describes itself as employee-owned and active in several regions. Buyers should compare units at the site's summer design point. The selection should state glycol level, altitude, sound limits, backup needs, and water quality. The bid should also state fan power and pressure drop. It should cover plume, control links, and service access. The two linked products create different utility duties. A dry cooler avoids routine evaporation. Its temperature margin falls as outdoor dry-bulb temperature rises. The HXV can use evaporation to extend output. That mode adds water treatment, discharge, drift, hygiene, and winter work. Public pages do not give one annual energy or water result for all sites. Buyers should require an hourly climate model and clear mode-change logic. They should ask for design-day output after a fan or pump failure. The design also needs basin and coil freeze protection. Sound must be checked at day and night settings. Service space must fit the proposed roof or yard. → Baltimore Aircoil Company, commonly called BAC, makes outdoor heat-rejection equipment rather than the liquid loop inside the server.

  • EVAPCO description: EVAPCO supplies facility-side heat rejection for data centers. Its range includes the eco-Air dry coolers and larger field-built designs. The EAW-HD APEX and EAW-DD Double Stack aim to reject more heat in less plan area. They operate without routine evaporation. EVAPCO publishes ratings certified by the Cooling Technology Institute for selected lines. It also offers factory assembly and controls. Those facts do not prove capacity at a site without a thermal selection. Procurement should test the actual inlet and outlet fluid temperatures. It should use the peak outdoor dry-bulb value, glycol level, and site elevation. The review must also cover hot-air return, sound limits, fan failures, and plant backup. Certification and a thermal guarantee apply at set rating conditions. They do not show whether a roof layout will pull hot discharge air back into the coils. They also do not prove outlet temperature after a cell, power feed, or panel fails. Public sources omit installed cost and delivery time. They also omit yearly fan energy and site staffing. Buyers should request the selection sheet and test tolerance. They need an electrical list for each fan and the lowest stable speed. The bid should state control points, coil cleaning, corrosion treatment, freeze steps, lifting needs, and structural loads. A layout review should use the real buildings and local winds. → EVAPCO supplies facility-side heat rejection for data centers through eco-Air dry coolers and larger field-built designs.

  • Güntner description: Güntner makes finned-coil heat exchangers and dry coolers. They serve refrigeration, process, building, and information-technology loads. Its Flat and V-shape VARIO lines offer many choices. Buyers can select coils, fans, controls, materials, and sound treatments. The V-shape line can add hydroBLU adiabatic pre-cooling. Data-center cases show the units rejecting heat from immersion systems. That evidence supports a facility-side role, not server compatibility. Buyers need a project selection for the hottest design hour. It should include glycol, fouling, altitude, fan staging, and sound limits. It should also cover hot-air return and freeze safety. If adiabatic help is fitted, the study must state water use. The bid must show output after a fan or control fault. A family name alone does not make bids equal. Coil shape, circuiting, metal, fan count, motors, controls, coatings, and accessories can all change duty. They can also change pressure loss, sound, water use, space, and service work. Procurement should fix those choices to a stated duty. It should require data for normal, peak, low-load, and fault states. The contract must name who supplies pumps and expansion gear. It must also assign air removal, loop exchangers, water treatment, steel, and plant controls. A dry cooler alone does not warrant the full heat-rejection system. → Güntner makes finned-coil heat exchangers and dry coolers for refrigeration, process, building, and information-technology loads.

  • Vahterus description: Vahterus designs gasket-free Plate & Shell Heat Exchangers. Welded round plate packs sit inside pressure shells. The design can keep two fluids apart during cooling, condensing, evaporation, or heat recovery. Each unit is selected for its duty. There is no single megawatt rating for the whole range. Vahterus lists nine plate sizes. They include the PSHE 7 and PSHE 9 in this batch. Nozzle size and surface area do not replace a heat calculation. Data-center buyers should state both fluids and their flow rates. They should state all supply and return temperatures. The schedule needs allowed approach, pressure loss, fouling, and design pressure. It must also cover metals, cleaning, leak detection, isolation, bypass, and vessel codes. A welded exchanger has no plate-pack gaskets. That choice also changes inspection, cleaning, repair, and later growth. Buyers should ask how the selected unit will be cleaned. They should define when fouling or blockage calls for action. The bid must say if the unit opens for service. It must explain how an internal leak will be found. Public size tables omit data-center references and prices. They also omit lead times, duty guarantees, and a standard spare plan. Final review needs certified calculations and shop drawings. It also needs code papers, weld checks, nozzle loads, vents, drains, supports, and an isolation plan. Service must not remove required cooling duty. → Vahterus designs gasket-free Plate & Shell Heat Exchangers with welded round plate packs inside pressure shells.

  • SWEP description: SWEP makes brazed plate heat exchangers. They can separate loops in free cooling, coolant distribution units, mechanical cooling, and heat reuse. SWEP documents B439 and B649 units at Infosys data centers. They keep cooling-tower water apart from a cleaner inner loop. Brazed construction makes a compact sealed unit. It also changes inspection, cleaning, repair, and final replacement. Buyers need a thermal selection for the stated fluids and temperatures. It must cover flow, approach, pressure loss, fouling, metal fit, and design pressure. The plan should also cover parallel flow balance and isolation. It must explain cross-contamination alarms and replacement access. The Infosys case proves product use. It does not set one rating or service interval for every site. Public sources omit exact plate count and brazing alloy for each unit. They also omit pressure loss, approach, water tests, cleaning history, and measured savings. Procurement should name the exact article and factory build. It should set strainer and water-quality limits. Clean and fouled duty both need guarantees. Buyers should decide if several isolated units are needed for service and fault tolerance. The bid should state chemical-cleaning limits and flushing points. It should show lifting and replacement space. It must also name the leak monitor and the party that balances parallel units. → SWEP makes brazed plate heat exchangers that can separate loops in free cooling, coolant distribution units, mechanical cooling, and heat reuse. SWEP documents B439 and B649 units at Infosys data centers, where they keep cooling-tower water apart from a cleaner inner loop. Brazed construction produces a compact sealed unit but changes inspection, cleaning, repair, and eventual replacement. Thermal selection has to use the stated fluids and temperatures, with flow, approach, pressure loss, fouling, metal compatibility, and design pressure. It also needs parallel-flow balance, isolation, cross-contamination alarms, and replacement access. The Infosys installation confirms product use, not a universal rating or service interval. SWEP does not publish the exact plate count, brazing alloy, pressure loss, approach, water tests, cleaning history, or measured savings for each installed unit. Name the exact article and factory build, then set strainer and water-quality limits. Clean and fouled duty both need guarantees. Decide whether several isolated units are necessary for service and fault tolerance. The bid should state chemical-cleaning limits, flushing points, lifting and replacement space, the leak monitor, and responsibility for balancing parallel units.
  • MITA Group description: MITA Group covers plant-side cooling through specialist firms. They include MITA Cooling Technologies in Italy and TORRAVAL Cooling in Spain. MITA makes factory-built open and closed evaporative towers. TORRAVAL designs larger custom towers. Its CTFP units serve a Barcelona data-processing center. This range matters when a designer must choose direct-contact tower water or a closed process loop. It does not remove the need for a site plant design. Buyers should compare duty at the site's wet-bulb condition. They need yearly and peak water use, fan and pump energy, drift, and plume. The review must cover treatment, discharge, hygiene, sound, backup, and materials. It must also cover winter use, access, controls, assembly, and local service. Contract lines need care because the products use MITA and TORRAVAL brands in one group. A tender should name the legal seller and factory. It should name the party that guarantees duty and supplies controls. It must also assign startup, warranty, and long-term service. The Barcelona case confirms sixteen towers. It withholds the operator, duty schedule, measured utilities, and test results. Buyers should ask for a similar site at the same scale and climate. They need the certified selection and test tolerance. The bid should state cycles of concentration, blowdown, drift, plume control, and cleaning. It must assign legionella management. It should also show capacity after the largest likely equipment or utility fault. → MITA Group covers plant-side cooling through MITA Cooling Technologies in Italy and TORRAVAL Cooling in Spain. MITA makes factory-built open and closed evaporative towers, while TORRAVAL designs larger custom towers. TORRAVAL CTFP units serve a Barcelona data-processing center. The portfolio gives designers a choice between direct-contact tower water and a closed process loop, but either option still requires a site plant design. Compare duty at the site's wet-bulb condition along with yearly and peak water use, fan and pump energy, drift, and plume. Treatment, discharge, hygiene, sound, backup, materials, winter operation, access, controls, assembly, and local service also need review. Contract boundaries deserve attention because the products use MITA and TORRAVAL brands within one group. A tender should name the legal seller, factory, duty guarantor, controls supplier, startup provider, warranty holder, and long-term service party.

  • Mitsubishi Heavy Industries Thermal Systems description: Mitsubishi Heavy Industries Thermal Systems sells centrifugal chillers. Its published portfolio spans 150 to 6,000 refrigeration tons. The ETI-Z and GART-ZE/ZEI lines use hydrofluoroolefin refrigerants with low global warming potential. They cover different plant sizes and offer inverter choices. The company lists data centers as an application. It also names Shirakawa Data Center. The public page omits the installed model, count, duty, efficiency, and startup date. This batch therefore does not create a site record from that reference. Buyers need project-specific full-load and part-load selections. They should set chilled-water and condenser-water limits. The bid must cover refrigerant supply, starting current, harmonics, restart order, and backup. It also needs tube-cleaning access, control links, service scope, and witnessed factory tests. A tonnage range does not show how many machines a strong plant needs. It also does not show behavior as computing load rises. Qualification should state the compressor and drive layout. It should state minimum stable load, surge control, and condenser-water reset. Efficiency is needed at each staging point. Derating must be shown after loss of a compressor, chiller, pump, or tower cell. Public pages omit price, lead time, fleet reliability, site test results, and local parts promises. Resolve those gaps through the bid, test plan, reference calls, refrigerant plan, maintenance scope, and promised emergency response. → Mitsubishi Heavy Industries Thermal Systems sells centrifugal chillers across a published range of 150 to 6,000 refrigeration tons.

  • Mitsubishi Electric Hydronics & IT Cooling Systems description: Mitsubishi Electric Hydronics & IT Cooling Systems designs applied cooling. It serves comfort, process, and information-technology sites. Its portfolio joins Climaveneta chillers with RC critical-cooling gear. The range includes free-cooling chillers for hyperscale and colocation data centers. The two linked products use different compressor designs. One uses oil-free centrifugal compressors. The other uses inverter screw compressors. They are not equal choices. Buyers should compare yearly energy at their own water temperatures and climate. They should compare compressor and fan backup. The study must cover free-cooling changeover and glycol use. It also needs restart time, refrigerant rules, room heat, sound, controls, and service access. Factory tests and local support matter too. The linked families do not assign the rack loop, room air handlers, pumps, power, or outdoor layout. Procurement should define each interface. It should require a yearly study with the site's weather file and phased load. That study must use the planned supply and return temperatures, glycol level, and reserve. Tests should cover mechanical, hybrid, and free-cooling mode changes. They should measure output after a circuit or fan fault. The plan also needs power-loss restart, low-load stability, control points, data ownership, coil access, and winter protection. Buyers must confirm trained staff and refrigerant supply in the region. → Mitsubishi Electric Hydronics & IT Cooling Systems designs applied cooling for comfort, process, and information-technology sites.

  • CPC description: CPC, or Colder Products Company, supplies parts rather than a full rack-cooling system. Its Everis range has latched and blind-mate quick disconnects. These run from server links to larger rack-loop links. Its OCP-oriented UQD models are meant to support more than one source. Buyers should select the exact flow size, end fitting, seal, pressure and coolant mix. A shared size does not prove equal pressure drop, spill control or service life across brands. CPC gives useful data on wetted materials and connections. A project plan should still set cleanliness rules, cycle tests, side-load limits and a replacement policy. It should also name the party that owns the hose assembly. The company was founded in Minnesota in 1978. It is based in Arden Hills and operates within Dover. Buyers should ask whether CPC or the hose builder warrants the finished hose. They should ask which inspection records come with each lot. They should also confirm whether new socket and plug versions work with old ones. Public pages do not give a fleet-wide failure rate. They do not give one set replacement term or all test data for every coolant mix. These gaps matter. Parts with the same interface can still differ in insertion force, spill, inner volume and pressure loss. A rack test should check access, labels and clear proof of connection. It should also test removal while nearby branches stay live. → CPC, or Colder Products Company, supplies parts rather than a full rack-cooling system.

  • Stäubli description: Stäubli supplies connection hardware within the liquid loop, not the pumps, cold plates or facility heat rejection around it. Its data-center portfolio includes OCP-oriented UQD and blind-mate UQDB couplings as well as the CGD metal range used by Fujitsu in Fugaku. The published ranges cover several nominal diameters, seal choices and alignment formats, so procurement must identify a complete socket-and-plug combination rather than cite only a family name. Buyers should compare pressure loss at the required flow, drip and air-inclusion limits, allowable misalignment, mating cycles, coolant compatibility and whether a listed approval applies to the exact part number. Founded in 1892, Stäubli remains family owned and is headquartered in Pfäffikon, Switzerland. The Fugaku reference demonstrates scale and hot-swap use, but it does not publish the selected CGD size, coolant chemistry, observed leak rate or replacement history. A new buyer should request test reports for both mating halves, tolerance data for the actual blind-mate guide system, and confirmation that seals, lubricants and surface finishes comply with the server vendor's water-quality rules. The commercial review should identify regional stocking, special tooling, lot traceability and the party responsible when a coupling, hose or manifold interface causes an imbalance. Multi-source claims should be verified through cross-mating tests under pressure rather than dimensional drawings alone. → Stäubli supplies connection hardware within the liquid loop, not the pumps, cold plates or facility heat rejection around it.

  • Parker Hannifin description: Parker Hannifin sells parts that move fluid from coolant distribution units to manifolds and cold plates. The two linked manifold lines are made for industrial liquid, gas, steam and hydraulic work. Parker does not market them as ready-made rack manifolds. They show its 316-stainless distribution hardware and the options it can build. Use in a technology-coolant loop would need project tests. Those tests should cover flow balance, cleanliness, glycol, branch links, pressure drop and service space. Parker also sells OCP-oriented quick disconnects, tube, hose and valves for data-center liquid cooling. This wide range may reduce handoffs between part suppliers. It does not create a tested rack-loop assembly or one system warranty. Parker is based in Cleveland and trades on the New York Stock Exchange. Buyers should ask which Parker unit owns the proposed assembly. They should also ask if adapting an industrial manifold would void any cleanliness or material claim. Public sources do not give rack sizes, branch Cv values, inner volume or flush steps. They also do not show an OCP test for HPAHM or HPAHMC. The design review should show how shutoff valves, quick disconnects, drains, vents and sensors fit together. Ask for full-weld and non-destructive-test records. One named builder should own branch balance, pressure tests and warranty handoffs across all Parker parts. → Parker Hannifin sells parts that move fluid from coolant distribution units to manifolds and cold plates.

  • USystems description: USystems concentrates on close-coupled air-assisted liquid cooling. Its ColdLogik rear doors replace or attach to a rack rear door, transfer server exhaust heat to water and return near-room-temperature air without requiring processor cold plates. That can preserve standard server service procedures, but door weight, rack fit, fan interaction, condensation margin and facility-water availability remain project constraints. The linked CL20 and CL23 span medium- through very-high-density duties; their headline capacities use stated water conditions and should not be carried into a design without a project-specific coil, airflow and redundancy calculation. USystems publishes named installations at DataBank, Cambridge and other sites. It was established in 2003, operates from Bedford in the United Kingdom and is now a Legrand brand. Buyers should request capacity tables across inlet-water temperatures, server airflow and altitude, together with fan power, water-side pressure loss, sound and failure-mode data. A retrofit survey should confirm hinge loads, cabinet adapter frames, aisle clearance, hose bend radius, leak detection and how a loaded door is supported during server service. Public references do not disclose standardized installed cost, fleet-wide fan or valve failure rates, or current measured annual efficiency. Contracts should state whether USystems, the rack supplier or the mechanical contractor owns controls integration, condensation avoidance and cooling continuity when one door is opened or isolated. → USystems concentrates on close-coupled air-assisted liquid cooling.

USystems publishes named installations at DataBank, Cambridge and other sites. It was established in 2003, operates from Bedford in the United Kingdom and is now a Legrand brand. Request capacity tables across inlet-water temperatures, server airflow and altitude. Include fan power, water-side pressure loss, sound and failure-mode data. A retrofit survey should confirm hinge loads, cabinet adapter frames, aisle clearance, hose bend radius and leak detection. It should show how a loaded door is supported during server service. Available references omit standardized installed cost, fleet-wide fan or valve failure rates and current measured annual efficiency. Contracts should state whether USystems, the rack supplier or the mechanical contractor owns controls integration, condensation avoidance and cooling continuity when one door is opened or isolated.
  • Grundfos description: Grundfos operates mainly on the facility-water side of the cooling chain. Its data-center references cover split-case and end-suction pumps, controls and the MIXIT mixing-loop package used with direct-to-chip cooling at NorthC. Pump selection must be made at the actual duty point: flow, head, fluid temperature, glycol concentration, redundancy and control strategy determine energy use and whether the pump remains within an efficient operating region. The linked KPVS and NBG records illustrate two plant arrangements rather than rack-integrated pumps. Buyers should request certified curves, minimum-flow limits, motor and drive data, seal materials, service clearance, vibration criteria and a staged-control sequence. Grundfos was founded in 1945, is headquartered in Bjerringbro and is primarily owned by the Grundfos Foundation. Procurement should model the full operating map as racks are commissioned, because a pump selected for ultimate build-out may spend early years far from its best-efficiency region. The submittal should show net positive suction head margin, parallel-pump stability, motor and drive efficiency, harmonic treatment and restart behavior after a power interruption. Public case studies report project outcomes but do not provide raw trend data, standardized measurement boundaries or fleet-wide reliability. Buyers should therefore seek witnessed factory tests, recent references at comparable flow and fluid conditions, stocked critical spares and a clear division of responsibility between pump controls and the site building-automation system. → Grundfos operates mainly on the facility-water side of the cooling chain.

  • Armstrong Fluid Technology description: Armstrong Fluid Technology supplies pumps and plant controls. It does not supply server cold plates or rack manifolds. Its vertical in-line design aims to cut plant-room floor and pipe needs. Design Envelope versions add variable-speed controls and data links. Armstrong also packages full chilled-water plant rooms. Its Digital Realty HKG10 case documents that role. A package can reduce work in the field. Buyers must still separate package results from the stated limits of one pump line. Selection needs the project flow, head and fluid data. It also needs motor efficiency, the control plan, N+1 backup, minimum flow and service shutoff. Factory tests should be witnessed. Armstrong was founded in Toronto in 1934 and keeps its head office there. Buyers should ask for wire-to-water results over the expected yearly load, not one best point. A vertical in-line layout can save floor area. The design must still prove pipe-load limits, low vibration, lift access and shutoff for motor or seal work. The public HKG10 case does not name the pump models or plant tonnage. It gives no start-up data or current efficiency. Buyers should require a controls-point list and clear network ownership. They should also set cyber rules, failure and restart steps, a spare-drive plan and firm test points. Those points must state water temperature, glycol share and sensor accuracy. → Armstrong Fluid Technology supplies pumps and plant controls. It does not supply server cold plates or rack manifolds.

  • Belimo description: Belimo supplies water-loop controls, not full cooling loops. Its Energy Valve joins a pressure-independent valve with an ultrasonic flow meter. It also has heat sensors and control logic. The EPIV controls flow as system pressure changes. It does not have the same energy-meter features. Belimo lists these devices for coolant distribution units, cold plates and rear-door heat exchangers. It also lists two-phase condensers, computer room air handlers and fan walls. Buyers must size each valve for the real flow range and available pressure. They should then check glycol correction, sensor accuracy, fail position, network links and cyber risks. An oversized valve may spend most of its life near the lowest flow it can control. That can weaken control quality. Belimo was founded in 1975. It is based in Hinwil and listed on the SIX Swiss Exchange. The control plan should say what the building system commands. That may be position, flow, pressure difference or heat transfer. It should also state the local fallback after a link fails. Start-up tests should use the real glycol mix. They should check meter accuracy, straight pipe and sensor placement. Public pages do not give long-term data-center failure rates or one setup for every rack loop. Belimo tells liquid-cooling users to contact its data-center team. Buyers should set rules for firmware, passwords, cloud links, saved trends, alarms and actuator swaps. They should also state how valve data is checked against coolant distribution unit and plant meters. → Belimo supplies water-loop controls, not full cooling loops.

  • Wieland description: Wieland's electronics-cooling unit supplies cold plates, not full data-center loops. Its standard 4000-series plates use friction-stir welds and Micro Deformation Technology pin fins. A custom program can change the plate size and inner flow path for a given heat map. The linked products are broad heat-transfer parts. They are not proof of approval for a named processor, graphics chip or server. Buyers should provide the real chip package and heat flux. They should also state the mount load, inlet temperature, allowed pressure drop, coolant and leak-test rule. The contract must assign ownership of hoses, quick disconnects and the rack manifold. Product drawings help screen fit. They do not replace a heat test. Wieland was founded in Ulm in 1820 and is still based there. A test plan should map heat and flow. It should include pressure cycles, proof and burst tests, corrosion exposure and flatness after joining. It should also inspect the friction-stir weld. Public drawings do not state heat capacity, thermal resistance, pressure drop or proof pressure. They do not give the full wetted-material list for these two parts. Buyers should ask which sizes are fixed and which can change. They should define which design changes force a new test. Ask whether shipped units include serial records and cleanliness proof. The parties must also assign the server warranty, mounting hardware and interface material. → Wieland's electronics-cooling unit supplies cold plates, not full data-center loops.

  • Castrol description: Castrol brings lubricant formulation, materials testing, fluid handling, and a global supply organization to data-center cooling. Its current Castrol ON range includes synthetic-hydrocarbon dielectric fluids for single-phase immersion and a separate PG 25 fluid for direct liquid cooling. This batch links only the two immersion products for which Castrol publishes direct product data. The product sheets provide useful baseline properties, but typical values are not acceptance limits and do not establish compatibility with a particular server, tank, seal, cable, or warranty. Castrol also operates an immersion research installation at its Pangbourne headquarters with Hypertec servers and Submer tanks. That is a development environment, not evidence of a production customer fleet. Buyers should require the current regional safety data sheet, batch certificate, approved-material list, fire and spill plan, storage conditions, filtration and sampling limits, end-of-life route, and written approval from the tank and server suppliers. Public sources do not disclose delivered pricing, installed fleet size, fluid life in production, or independent long-duration reliability. A request for quotation should lock the exact DC 15 or DC 20 formulation and revision rather than permit an unspecified Castrol ON substitute. It should also identify who owns fluid analysis after commissioning, what measured change triggers filtration or replacement, how replacement fluid will be sourced in the operating region, and whether the tank warranty remains valid after top-ups from later production batches. → Castrol brings lubricant formulation, materials testing, fluid handling, and a global supply organization to data-center cooling.

  • Valvoline Global Operations description: Valvoline Global Operations has moved its fluid work into data-center cooling. It sells these products under the Beyond by Valvoline name. The cited range has two different fluids. HTF-DE1 is a dielectric fluid for immersion. PG25 Advanced serves direct-to-chip and heat-exchange loops. Valvoline also reports an 18-month test with Iceotope hardware. The test used HPE servers and NVIDIA A40 graphics processors. It proves one fluid and hardware mix. Its 5.2 kW load does not prove rack-scale capacity. It also does not qualify other servers or materials. Product supply varies by region. The public page omits the full chemistry and inhibitor pack. It also omits service life, dose tolerance, and a full list of approved wet materials. Buyers need current product and safety sheets. They need fluid limits, fill steps, and sample steps. The bid should include material approvals, warranty terms, dirt limits, fixes, storage life, and the final waste route. The company is an Aramco affiliate. It is not the public Valvoline retail business. HTF-DE1 and PG25 Advanced serve different cooling designs. They should not share one fluid rule, sample limit, or spill plan. Buyers must name the Valvoline legal entity that supplies each fluid. They should state where sealed baseline samples will be held. Lab review may or may not be part of the sale, so the contract must say. It must also divide action after a bad result among Valvoline, the cooling vendor, and the server maker. → Valvoline Global Operations has moved its fluid work into data-center cooling under the Beyond by Valvoline name.

It also needs to state whether laboratory interpretation is included and divide responsibility for an out-of-limit result among Valvoline, the cooling-system vendor, and the server manufacturer.
  • Ecolab description: Ecolab, through Nalco Water, supplies chemistry and controls for cooling water. It also offers monitoring, remote support, and field service. Its data-center work spans open towers, adiabatic heat rejection, and direct-to-chip loops. The linked products cover the facility-water side. 3D TRASAR Cooling Water joins chemistry with monitoring for towers and chillers. The adiabatic program adds conductivity and flow checks for each unit. It also adds central dosing, alarms, and digital records. Ecolab owns CoolIT Systems. This record covers Ecolab's water service, not CoolIT's cooling hardware. Buyers need one water specification that all equipment vendors accept. It should set limits for pH, conductivity, chlorides, hardness, corrosion, microbes, and suspended solids. It should also name sample methods and alarm limits. The contract must say who may dose or drain the system. Supplier-reported savings are not a project guarantee. Results depend on source water, metals, heat flux, tower cycles, weather, and sound operating practice. Public pages give no standard chemical formula or installed price. They also omit sensor calibration terms, data retention, and service response times. Open towers, adiabatic media, and closed technology loops have different risks and warranty limits. One master agreement must keep those programs distinct. It should name the approved lab methods and baseline samples. It should set report timing and data export rules. It should list escalation contacts, site visits, and consumable supply.

  • Xylem description: Xylem supplies the pumps and controls that move facility water through chilled-water, cooling-tower, heat-recovery, and some liquid-cooling interfaces. Its data-center brochure identifies Bell & Gossett end-suction and inline pumps, Goulds Water Technology multistage pumps, and hydrovar X smart-motor packages. The linked e-1510X and e-SV records represent two different duties: high-flow circulation and higher-head multistage service. Neither model number is a complete selection. A buyer must provide the actual flow, system curve, fluid and glycol concentration, temperature range, suction conditions, elevation, materials, redundancy philosophy, electrical service, controls, and expected turndown. Pump efficiency at the design point is not enough; phased data halls can operate at low load for years, and a standby pump only protects service if valves, power, controls, and automatic changeover are tested. Xylem publishes a named NREL deployment involving Bell & Gossett pumps and warm-water heat recovery. It does not disclose fleet-wide failure rates or guarantee that the same arrangement fits a direct-to-chip technology loop. Current headquarters information is taken from Xylem's 2025 annual report. A complete bid should identify the selected impeller, motor, seal, coating, drive, sensors, and control firmware rather than cite only a pump family. Buyers should require certified curves with the project operating points marked, witness or documented factory testing where appropriate, minimum continuous flow, spare rotating assemblies or drive strategy, and efficiency evidence at the expected first-phase as well as ultimate load. → Xylem supplies pumps and controls for chilled-water, cooling-tower, heat-recovery, and some liquid-cooling interfaces.

  • Siemens description: Siemens supplies power and building controls for data centers. It also sells fire, security, and cooling systems through Smart Infrastructure. This record covers two control layers. Desigo PXC4 is a set of programmable building controllers. White Space Cooling Optimization uses many temperature sensors and forecast software. It adjusts room cooling to the information-technology load. The products have different jobs. PXC4 runs plant and equipment steps. White Space Cooling Optimization maps air flow and guides room cooling. Siemens has a named Novva Data Centers case in Colorado Springs. Desigo PXC controllers use a flat design there. They control chillers, towers, pumps, and fans. Siemens reports no cooling downtime for a year and a half. It also reports large power savings. The work included new wires, new control code, and a wider cooling change. The controller alone did not create every result. Buyers need a full point list and sequence. They need a fault plan and a safe local mode. The design should cover sensor checks, networks, access, software, cloud terms, patches, and trend storage. Tests should cut power and links. They should also inject bad sensor values and fast compute-load changes. Public sources omit Novva's information-technology capacity and controller count. They also omit price and an outside audit. Local safety logic must remain distinct from high-level control. The contract must state what runs without a Siemens server, cloud service, or wide-area link.

  • Pall Corporation description: Pall Corporation makes filters and separation equipment for many industrial markets. The two linked records can serve facility water. Pall lists cooling water and treatment before reverse osmosis as uses. Its public pages do not qualify these products for a technology cooling loop. Ultipleat High Flow housings handle large flows. Profile UP cartridges offer many particle-removal grades. A generic cooling-water rating is not enough for a cold-plate loop. Buyers need the filter efficiency and its test basis. They need dirt capacity and clean pressure drop. They also need the final pressure drop, bypass action, collapse limit, seal data, extractables, and fluid fit. The smallest protected channel sets a key limit. The design must define filtration during the first flush. It must then state whether the permanent filter is full flow or side stream. Isolation, pressure alarms, safe element changes, spare stock, and waste handling also need clear plans. Pall gives detailed build and flow data. It gives no cited data-center deployment or server-loop test. Installed price and field service life are also unknown. Pall is a Danaher subsidiary. Buyers should confirm local supply and the exact build. The housing, cartridge, seal, and fluid must qualify as one set. A replacement that merely fits is not proven. Temporary debris removal is not the same as long-term polishing. The bid should state when bypass is allowed. It should show pressure loss with a clean and a loaded filter. The change method must keep dirt off the clean side near live cooling loads. → Pall Corporation makes filters and separation equipment for many industrial markets.

  • Veolia Water Technologies description: Veolia Water Technologies supplies water-treatment equipment, chemicals, controls, and digital monitoring. It also offers operating services. Its data-center material covers source water and open cooling loops. It also covers water recovery and reuse. E.C.O.Film uses chemistry with no phosphorus to control scale and rust. The TrueSense Ready-Set-Go controller checks pH, oxidation-reduction potential, and conductivity. It can also check chemical levels in supported programs. An Illinois case reports more tower cycles and less water use. The work added pH control, acid feed, remote checks, and alarms. Veolia reports the result, and the operator is not named. The case does not isolate the controller from the full treatment plan. Buyers need a water balance and a chemistry model. They need a review of all wet materials. The bid should show dosing, storage, spill control, samples, calibration, and alarm response. It also needs cyber terms, data rights, discharge review, and clear acceptance tests. The buyer should identify the actual contracting party. It may be Veolia Water Technologies, Veolia Water Technologies & Solutions, or a local affiliate. Public sources omit site capacity, city, contract value, and an outside audit. The proposal should name the Veolia entity that ships each chemical. It should say who owns controller settings and reads alarms. It should name who comes to site after a bad result. The bid must state the modeled starting water and the allowed quality range. It should set a baseline period and a test period. Data export, supplies, lab methods, and acid safety must be clear.

  • Smardt Chiller Group description: Smardt designs air-cooled, water-cooled, evaporatively cooled, and modular chillers around oil-free centrifugal compressors. Its Core and Ultra water-cooled ranges cover plant sizes from 45 to 3,600 refrigeration tons, while multi-compressor layouts provide staged capacity and some compressor-level redundancy. For a data-center procurement, the useful distinction is specialization: Smardt can engineer the chiller package, but pumps, towers or dry coolers, controls, and rack-side equipment still require a complete plant design. Buyers should obtain project-specific selections at the required chilled- and condenser-water temperatures, annual load calculations, refrigerant and service plans, restart behavior, and witnessed performance tests rather than extrapolating from range limits. Qualification should separate compressor redundancy from whole-chiller and whole-plant redundancy: continued operation after one compressor stops does not establish capacity after loss of a vessel, power feed, controller, pump, or condenser-water path. The public range pages also do not disclose delivered pricing, lead time, fleet-wide failure rates, or one standard efficiency valid across all configurations. Tender documents should therefore identify the exact model, rating standard, ambient and water design points, fouling assumptions, part-load sequence, allowable downtime, spare-parts commitment, and party responsible for integrated plant controls. → Smardt designs several types of chiller. They include air-cooled, water-cooled, evaporatively cooled, and modular units. The designs use oil-free centrifugal compressors.

Smardt can engineer the chiller package. Pumps, towers, dry coolers, controls, and rack-side gear still need a full plant design. Buyers should get a project selection at the required water temperatures. They should also request an annual load study and a refrigerant plan. The bid should cover service, restart behavior, and witnessed tests. Range limits alone are not enough. Qualification should separate compressor backup from whole-chiller backup. It should also separate both from plant backup. Operation after one compressor stops does not prove capacity after other faults. A vessel, power feed, controller, pump, or condenser-water path can still fail. Public range pages do not give delivered price or lead time. They also omit fleet failure rates and one standard efficiency for all builds. Tender documents should name the exact model and rating standard. They should state the air and water design points and fouling basis. They should also define the part-load sequence, allowed downtime, spare-parts promise, and owner of plant controls.
  • Baltimore Aircoil Company description: Baltimore Aircoil Company, commonly called BAC, makes outdoor heat-rejection equipment rather than server-side liquid loops. Its data-center range includes the TrilliumSeries dry cooler and the HXV hybrid cooler, allowing a plant designer to trade footprint, fan energy, and peak water use against required leaving-fluid temperature. BAC reports operating since 1938 and describes itself as employee-owned, with product and service coverage across multiple regions. Buyers should compare units at site-specific summer design conditions, glycol concentration, altitude, sound limits, redundancy, and water-quality assumptions, and should require fan power, pressure drop, plume behavior, controls integration, and maintenance access in the submittal. The two linked products represent materially different utility and operating obligations. A dry cooler avoids routine evaporation but loses temperature margin as outdoor dry-bulb temperature rises; the HXV can use evaporation to extend performance but introduces water treatment, discharge, drift, hygiene, and winterization work. Public product pages do not provide a universal annual energy or water result. A procurement team should require hourly climate modeling, explicit mode-change logic, design-day derating after a fan or pump failure, basin and coil freeze protection, sound at day and night setpoints, and confirmation that service clearances fit the proposed roof or yard layout. → Baltimore Aircoil Company, commonly called BAC, makes outdoor heat-rejection gear. It does not make the liquid loop inside the server. Its data-center range includes the TrilliumSeries dry cooler and the HXV hybrid cooler. These products let a plant designer trade space, fan energy, and peak water use against outlet temperature. BAC reports operating since 1938. It describes itself as employee-owned and active in several regions. Buyers should compare units at the site's summer design point. The selection should state glycol level, altitude, sound limits, backup needs, and water quality. The bid should also state fan power and pressure drop. It should cover plume, control links, and service access. The two linked products create different utility duties. A dry cooler avoids routine evaporation. Its temperature margin falls as outdoor dry-bulb temperature rises. The HXV can use evaporation to extend output. That mode adds water treatment, discharge, drift, hygiene, and winter work. Public pages do not give one annual energy or water result for all sites. Buyers should require an hourly climate model and clear mode-change logic. They should ask for design-day output after a fan or pump failure. The design also needs basin and coil freeze protection. Sound must be checked at day and night settings. Service space must fit the proposed roof or yard.
  • EVAPCO description: EVAPCO supplies facility-side heat rejection for data centers, including the eco-Air family of dry coolers and larger field-erected configurations. The EAW-HD APEX and EAW-DD Double Stack products target high heat rejection per unit of plan area while operating without routine evaporation. EVAPCO publishes CTI-certified ratings for selected dry-cooler lines and offers controls and factory assembly, but those facts do not establish site capacity without a thermal selection. Procurement should test performance at actual entering and leaving fluid temperatures, peak dry-bulb conditions, glycol concentration, elevation, recirculation, sound restrictions, fan-failure cases, and the required plant redundancy. CTI certification and a thermal performance guarantee address defined rating conditions; they do not answer whether a roof arrangement will recirculate hot discharge air or whether the plant can meet outlet temperature after a cell, power feed, or control panel is unavailable. The public sources also do not disclose installed cost, delivery schedule, annual fan energy, or maintenance staffing for a particular site. Buyers should request the selection printout, test code and tolerance, fan-by-fan electrical schedule, minimum stable speed, controls points, coil-cleaning method, corrosion treatment, freeze strategy, lifting plan, structural reactions, and a layout review using the actual surrounding buildings and prevailing winds. → EVAPCO supplies facility-side heat rejection for data centers. Its range includes the eco-Air dry coolers and larger field-built designs. The EAW-HD APEX and EAW-DD Double Stack aim to reject more heat in less plan area. They operate without routine evaporation. EVAPCO publishes ratings certified by the Cooling Technology Institute for selected lines. It also offers factory assembly and controls. Those facts do not prove capacity at a site without a thermal selection. Procurement should test the actual inlet and outlet fluid temperatures. It should use the peak outdoor dry-bulb value, glycol level, and site elevation. The review must also cover hot-air return, sound limits, fan failures, and plant backup. Certification and a thermal guarantee apply at set rating conditions. They do not show whether a roof layout will pull hot discharge air back into the coils. They also do not prove outlet temperature after a cell, power feed, or panel fails. Public sources omit installed cost and delivery time. They also omit yearly fan energy and site staffing. Buyers should request the selection sheet and test tolerance. They need an electrical list for each fan and the lowest stable speed. The bid should state control points, coil cleaning, corrosion treatment, freeze steps, lifting needs, and structural loads. A layout review should use the real buildings and local winds.
  • Güntner description: Güntner manufactures finned-coil heat exchangers and dry coolers for refrigeration, process, HVAC, and information-technology loads. Its Flat and V-shape VARIO families can be configured with different coils, fans, controls, materials, and sound treatments; the V-shape line can also add hydroBLU adiabatic pre-cooling. Published data-center cases show the equipment rejecting heat from immersion systems, which is evidence of a facility-side role rather than server compatibility. Buyers should require a project selection that accounts for hottest-hour ambient conditions, glycol, fouling, elevation, fan staging, acoustic limits, hot-air recirculation, freeze protection, water use when adiabatic assistance is fitted, and capacity after a fan or control failure. Configuration breadth means a family name alone is not a comparable bid. Coil geometry, circuiting, metallurgy, fan quantity, motor type, controls, coatings, and adiabatic accessories can change capacity, pressure drop, sound, water demand, footprint, and service procedure. Procurement should lock those choices to a scheduled duty and require performance at normal, peak, minimum-load, and failure conditions. It should also identify who supplies pumps, expansion and air separation, intermediate heat exchangers, water treatment for any assisted mode, structural steel, and supervisory controls, because the dry cooler does not by itself define or warrant the complete heat-rejection system. → Güntner makes finned-coil heat exchangers and dry coolers. They serve refrigeration, process, building, and information-technology loads. Its Flat and V-shape VARIO lines offer many choices. Buyers can select coils, fans, controls, materials, and sound treatments. The V-shape line can add hydroBLU adiabatic pre-cooling. Data-center cases show the units rejecting heat from immersion systems. That evidence supports a facility-side role, not server compatibility. Buyers need a project selection for the hottest design hour. It should include glycol, fouling, altitude, fan staging, and sound limits. It should also cover hot-air return and freeze safety. If adiabatic help is fitted, the study must state water use. The bid must show output after a fan or control fault. A family name alone does not make bids equal. Coil shape, circuiting, metal, fan count, motors, controls, coatings, and accessories can all change duty. They can also change pressure loss, sound, water use, space, and service work. Procurement should fix those choices to a stated duty. It should require data for normal, peak, low-load, and fault states. The contract must name who supplies pumps and expansion gear. It must also assign air removal, loop exchangers, water treatment, steel, and plant controls. A dry cooler alone does not warrant the full heat-rejection system.
  • Vahterus description: Vahterus designs gasket-free Plate & Shell Heat Exchangers around welded circular plate packs inside pressure shells. The architecture can isolate fluids in cooling, condensing, evaporating, and heat-recovery duties and is custom selected rather than sold on one universal megawatt rating. The company publishes nine plate sizes, including the PSHE 7 and PSHE 9 represented in this batch, but nozzle and surface-area ranges are not substitutes for a thermal calculation. Data-center buyers should specify both fluids, flow rates, supply and return temperatures, allowable approach temperature and pressure drop, fouling allowance, design pressure, metallurgy, cleanability, leak detection, isolation, bypass, and local pressure-vessel certification. A fully welded exchanger removes plate-pack gaskets from the design, but that construction also affects inspection, mechanical cleaning, repair, and capacity expansion. Buyers should ask how the selected unit will be cleaned for the stated fluids, what fouling or plugging evidence triggers intervention, whether an openable or fully welded execution is proposed, and how an internal leak between circuits would be detected. The public size table does not disclose data-center references, prices, lead times, thermal guarantees, or standard spare strategy. Final qualification needs certified calculations, fabrication drawings, code documentation, weld inspection requirements, nozzle loads, vent and drain provisions, support design, and an isolation arrangement that permits service without losing the required cooling duty. → Vahterus designs gasket-free Plate & Shell Heat Exchangers. Welded round plate packs sit inside pressure shells. The design can keep two fluids apart during cooling, condensing, evaporation, or heat recovery. Each unit is selected for its duty. There is no single megawatt rating for the whole range. Vahterus lists nine plate sizes. They include the PSHE 7 and PSHE 9 in this batch. Nozzle size and surface area do not replace a heat calculation. Data-center buyers should state both fluids and their flow rates. They should state all supply and return temperatures. The schedule needs allowed approach, pressure loss, fouling, and design pressure. It must also cover metals, cleaning, leak detection, isolation, bypass, and vessel codes. A welded exchanger has no plate-pack gaskets. That choice also changes inspection, cleaning, repair, and later growth. Buyers should ask how the selected unit will be cleaned. They should define when fouling or blockage calls for action. The bid must say if the unit opens for service. It must explain how an internal leak will be found. Public size tables omit data-center references and prices. They also omit lead times, duty guarantees, and a standard spare plan. Final review needs certified calculations and shop drawings. It also needs code papers, weld checks, nozzle loads, vents, drains, supports, and an isolation plan. Service must not remove required cooling duty.
  • SWEP description: SWEP manufactures brazed plate heat exchangers used as loop separators in data-center free cooling, coolant distribution units, mechanical cooling, and heat-reuse systems. Its B439 and B649 products have direct company-documented use in Infosys data centers, where they separate cooling-tower water from a cleaner internal loop. Brazed construction offers a compact sealed assembly, but it changes inspection, cleaning, repair, and end-of-life choices compared with gasketed plate-and-frame equipment. Buyers should require a thermal selection for fluid chemistry, duty temperatures, flow, approach, pressure drop, fouling, material compatibility, design pressure, parallel-unit balancing, isolation, cross-contamination detection, and replacement access. The named Infosys reference supports use of the products, not a universal thermal rating or maintenance interval. The public sources do not state the exact plate count, brazing alloy, pressure loss, approach temperature, water analysis, cleaning history, or measured energy savings for every installed unit. Procurement should identify the precise article number and manufacturing configuration, establish strainers and water-quality limits, specify clean and fouled guarantees, and decide whether several isolated exchangers are needed for maintainability and fault tolerance. It should also document chemical-cleaning compatibility, flushing connections, lifting and replacement space, leak-monitoring method, and the party responsible for hydraulic balancing when units operate in parallel. → SWEP makes brazed plate heat exchangers. They can separate loops in free cooling, coolant distribution units, mechanical cooling, and heat reuse. SWEP documents B439 and B649 units at Infosys data centers. They keep cooling-tower water apart from a cleaner inner loop. Brazed construction makes a compact sealed unit. It also changes inspection, cleaning, repair, and final replacement. Buyers need a thermal selection for the stated fluids and temperatures. It must cover flow, approach, pressure loss, fouling, metal fit, and design pressure. The plan should also cover parallel flow balance and isolation. It must explain cross-contamination alarms and replacement access. The Infosys case proves product use. It does not set one rating or service interval for every site. Public sources omit exact plate count and brazing alloy for each unit. They also omit pressure loss, approach, water tests, cleaning history, and measured savings. Procurement should name the exact article and factory build. It should set strainer and water-quality limits. Clean and fouled duty both need guarantees. Buyers should decide if several isolated units are needed for service and fault tolerance. The bid should state chemical-cleaning limits and flushing points. It should show lifting and replacement space. It must also name the leak monitor and the party that balances parallel units.
  • MITA Group description: MITA Group covers plant-side thermal equipment through specialist businesses including MITA Cooling Technologies in Italy and TORRAVAL Cooling in Spain. MITA Cooling Technologies makes factory-assembled open- and closed-circuit evaporative towers, while TORRAVAL designs larger and customized towers such as the CTFP units documented at a Barcelona data-processing center. This portfolio makes the group relevant where a data-center designer must choose between direct-contact tower water and a closed process loop, but it does not remove the need for project-specific plant engineering. Buyers should compare thermal duty at the site's wet-bulb conditions, annual and peak water use, fan and pump energy, drift, plume, water treatment and discharge, hygiene controls, sound, redundancy, materials, winter operation, access, controls integration, factory or field assembly, and local service. Contracting boundaries need particular attention because the linked products carry MITA and TORRAVAL brands within the same group. A tender should identify the legal seller, manufacturing site, thermal guarantor, controls supplier, commissioning party, and organization responsible for warranty and long-term service in the project country. The Barcelona case confirms a sixteen-tower project but withholds the operator, thermal schedule, measured utilities, and acceptance results. Buyers should therefore ask for a comparable reference at the proposed scale and climate, the certified selection and test tolerance, expected cycles of concentration and blowdown, drift and plume controls, basin and coil cleaning procedures, legionella management responsibilities, and capacity after the largest credible equipment or utility failure. → MITA Group covers plant-side cooling through specialist firms. They include MITA Cooling Technologies in Italy and TORRAVAL Cooling in Spain. MITA makes factory-built open and closed evaporative towers. TORRAVAL designs larger custom towers. Its CTFP units serve a Barcelona data-processing center. This range matters when a designer must choose direct-contact tower water or a closed process loop. It does not remove the need for a site plant design. Buyers should compare duty at the site's wet-bulb condition. They need yearly and peak water use, fan and pump energy, drift, and plume. The review must cover treatment, discharge, hygiene, sound, backup, and materials. It must also cover winter use, access, controls, assembly, and local service. Contract lines need care because the products use MITA and TORRAVAL brands in one group. A tender should name the legal seller and factory. It should name the party that guarantees duty and supplies controls. It must also assign startup, warranty, and long-term service. The Barcelona case confirms sixteen towers. It withholds the operator, duty schedule, measured utilities, and test results. Buyers should ask for a similar site at the same scale and climate. They need the certified selection and test tolerance. The bid should state cycles of concentration, blowdown, drift, plume control, and cleaning. It must assign legionella management. It should also show capacity after the largest likely equipment or utility fault.
  • Mitsubishi Heavy Industries Thermal Systems description: Mitsubishi Heavy Industries Thermal Systems sells centrifugal chillers from 150 to 6,000 refrigeration tons across its published portfolio. The ETI-Z and GART-ZE/ZEI ranges use low-global-warming-potential HFO refrigerants and cover different plant scales, with inverter options available. The company identifies data centers as an application and names Shirakawa Data Center, but its public application page does not disclose installed model, quantity, capacity, efficiency, or commissioning date, so this batch does not create a deployment record from that reference. Buyers should require project-specific full- and part-load selections, chilled- and condenser-water limits, refrigerant availability, harmonic and starting-current data, restart sequence, redundancy, tube-cleaning access, controls integration, service coverage, and witnessed factory testing. A published refrigeration-ton range cannot answer how many machines a resilient plant needs or how they behave as the information-technology load ramps. Qualification should include the selected compressor and drive arrangement, minimum stable load, surge-control method, condenser-water reset envelope, efficiency at each planned staging point, and derating after a compressor, chiller, pump, or cooling-tower cell fails. The public pages do not provide commercial terms, lead times, fleet reliability, data-center acceptance results, or regional parts commitments. Those unknowns should be resolved through the bid schedule, factory-test protocol, reference calls, refrigerant supply plan, preventive-maintenance scope, and guaranteed emergency response time. → Mitsubishi Heavy Industries Thermal Systems sells centrifugal chillers. Its published portfolio spans 150 to 6,000 refrigeration tons. The ETI-Z and GART-ZE/ZEI lines use hydrofluoroolefin refrigerants with low global warming potential. They cover different plant sizes and offer inverter choices. The company lists data centers as an application. It also names Shirakawa Data Center. The public page omits the installed model, count, duty, efficiency, and startup date. This batch therefore does not create a site record from that reference. Buyers need project-specific full-load and part-load selections. They should set chilled-water and condenser-water limits. The bid must cover refrigerant supply, starting current, harmonics, restart order, and backup. It also needs tube-cleaning access, control links, service scope, and witnessed factory tests. A tonnage range does not show how many machines a strong plant needs. It also does not show behavior as computing load rises. Qualification should state the compressor and drive layout. It should state minimum stable load, surge control, and condenser-water reset. Efficiency is needed at each staging point. Derating must be shown after loss of a compressor, chiller, pump, or tower cell. Public pages omit price, lead time, fleet reliability, site test results, and local parts promises. Resolve those gaps through the bid, test plan, reference calls, refrigerant plan, maintenance scope, and promised emergency response.
  • Mitsubishi Electric Hydronics & IT Cooling Systems description: Mitsubishi Electric Hydronics & IT Cooling Systems, or MEHITS, designs applied cooling for comfort, industrial processes, and information-technology facilities. Its portfolio joins Climaveneta air- and water-cooled chillers with RC critical-cooling equipment, including free-cooling chillers designed specifically for hyperscale and colocation data centers. The two products in this batch represent oil-free centrifugal and inverter-screw air-cooled approaches, not interchangeable selections. Buyers should compare annual energy at their water temperatures and climate, compressor and fan redundancy, free-cooling switchover, glycol strategy, fast restart, refrigerant regulation, heat left in room air, sound, controls, maintainability, factory acceptance testing, and service capability in the project country. The product relationship establishes available chiller families, not responsibility for the rack-side loop, room air handlers, pumps, electrical infrastructure, or outdoor layout around each unit. Procurement should define those interfaces and require an annual simulation using the site's weather file, phased load profile, supply and return temperatures, glycol concentration, and required reserve. It should also test transition among mechanical, hybrid, and free-cooling modes, capacity during a circuit or fan failure, restart after power loss, low-load stability, control points and data ownership, coil-cleaning access, winter protection, and the availability of trained technicians and refrigerant in the operating region. → Mitsubishi Electric Hydronics & IT Cooling Systems designs applied cooling. It serves comfort, process, and information-technology sites. Its portfolio joins Climaveneta chillers with RC critical-cooling gear. The range includes free-cooling chillers for hyperscale and colocation data centers. The two linked products use different compressor designs. One uses oil-free centrifugal compressors. The other uses inverter screw compressors. They are not equal choices. Buyers should compare yearly energy at their own water temperatures and climate. They should compare compressor and fan backup. The study must cover free-cooling changeover and glycol use. It also needs restart time, refrigerant rules, room heat, sound, controls, and service access. Factory tests and local support matter too. The linked families do not assign the rack loop, room air handlers, pumps, power, or outdoor layout. Procurement should define each interface. It should require a yearly study with the site's weather file and phased load. That study must use the planned supply and return temperatures, glycol level, and reserve. Tests should cover mechanical, hybrid, and free-cooling mode changes. They should measure output after a circuit or fan fault. The plan also needs power-loss restart, low-load stability, control points, data ownership, coil access, and winter protection. Buyers must confirm trained staff and refrigerant supply in the region.
  • CPC description: CPC, or Colder Products Company, is a component supplier rather than a complete rack-cooling integrator. Its Everis range covers latched and blind-mate quick disconnects from server-level connections toward larger rack-loop interfaces, with OCP-oriented UQD models intended to support multi-sourcing. Buyers should select the exact flow size, termination, seal, pressure and coolant combination; a compatible envelope does not establish equal pressure drop, spillage or lifecycle performance across suppliers. CPC publishes useful wetted-material and connection data, but a project submittal should still define cleanliness, mating-cycle testing, allowable side load, replacement policy and responsibility for the assembled hose. The company was founded in Minnesota in 1978, is headquartered in Arden Hills and operates within Dover. Procurement should also ask whether CPC or the hose assembler warrants the finished assembly, which inspection records accompany each lot, and whether socket and plug revisions remain backward compatible. Public product pages do not disclose a fleet-wide field-failure rate, a standard preventive-replacement interval, or the complete qualification evidence behind every coolant combination. Those unknowns matter because a nominally interchangeable connector can still differ in insertion force, residual spill, internal volume and pressure loss. A rack mock-up should therefore test access, labeling, connection confirmation and technician removal while adjacent branches remain live. → CPC, or Colder Products Company, supplies parts rather than a full rack-cooling system. Its Everis range has latched and blind-mate quick disconnects. These run from server links to larger rack-loop links. Its OCP-oriented UQD models are meant to support more than one source. Buyers should select the exact flow size, end fitting, seal, pressure and coolant mix. A shared size does not prove equal pressure drop, spill control or service life across brands. CPC gives useful data on wetted materials and connections. A project plan should still set cleanliness rules, cycle tests, side-load limits and a replacement policy. It should also name the party that owns the hose assembly. The company was founded in Minnesota in 1978. It is based in Arden Hills and operates within Dover. Buyers should ask whether CPC or the hose builder warrants the finished hose. They should ask which inspection records come with each lot. They should also confirm whether new socket and plug versions work with old ones. Public pages do not give a fleet-wide failure rate. They do not give one set replacement term or all test data for every coolant mix. These gaps matter. Parts with the same interface can still differ in insertion force, spill, inner volume and pressure loss. A rack test should check access, labels and clear proof of connection. It should also test removal while nearby branches stay live.
  • Parker Hannifin description: Parker Hannifin offers fluid-conveyance components from coolant-distribution units through manifolds and cold plates. The two linked distribution-manifold families are built for industrial liquid, gas, steam and hydraulic service rather than advertised as ready-made rack manifolds. They are included because they show Parker's configurable 316-stainless distribution hardware, but using one in a technology-coolant loop would require project qualification for flow balance, cleanliness, glycol chemistry, branch connections, pressure drop and service clearances. Parker separately markets OCP-oriented quick disconnects, tubing, hoses and valves for data-center liquid cooling. The broad catalog can reduce component handoffs, but it does not create a pre-qualified rack-loop assembly or a single performance warranty. Parker is headquartered in Cleveland and trades on the New York Stock Exchange. A buyer should require Parker to identify which division owns the submitted assembly and whether the industrial manifold catalog can be adapted without invalidating data-center cleanliness or material requirements. The public sources do not publish rack dimensions, branch Cv values, internal volume, flushing procedures or an OCP qualification for HPAHM or HPAHMC. Engineering review should also resolve how isolation valves, quick disconnects, drains, vents and sensors are combined, and whether full-penetration weld and non-destructive-test records are supplied. Any proposal should name one integrator responsible for branch balancing, hydrostatic testing and warranty coordination across Parker components. → Parker Hannifin sells parts that move fluid from coolant distribution units to manifolds and cold plates. The two linked manifold lines are made for industrial liquid, gas, steam and hydraulic work. Parker does not market them as ready-made rack manifolds. They show its 316-stainless distribution hardware and the options it can build. Use in a technology-coolant loop would need project tests. Those tests should cover flow balance, cleanliness, glycol, branch links, pressure drop and service space. Parker also sells OCP-oriented quick disconnects, tube, hose and valves for data-center liquid cooling. This wide range may reduce handoffs between part suppliers. It does not create a tested rack-loop assembly or one system warranty. Parker is based in Cleveland and trades on the New York Stock Exchange. Buyers should ask which Parker unit owns the proposed assembly. They should also ask if adapting an industrial manifold would void any cleanliness or material claim. Public sources do not give rack sizes, branch Cv values, inner volume or flush steps. They also do not show an OCP test for HPAHM or HPAHMC. The design review should show how shutoff valves, quick disconnects, drains, vents and sensors fit together. Ask for full-weld and non-destructive-test records. One named builder should own branch balance, pressure tests and warranty handoffs across all Parker parts.
  • Armstrong Fluid Technology description: Armstrong Fluid Technology supplies pumps and plant controls rather than server cold plates or rack manifolds. Its vertical in-line architecture is intended to reduce mechanical-room floor and piping requirements, while Design Envelope variants add variable-speed controls and communications. Armstrong also packages complete chilled-water plant rooms, as documented at Digital Realty HKG10. That broader delivery can reduce field integration, but buyers should separate factory-package performance from an individual pump's published maximum envelope. Selection still requires project flow and head, fluid properties, motor efficiency, control sequence, N+1 arrangement, minimum flow, service isolation and witnessed factory testing. Armstrong was founded in Toronto in 1934 and maintains its head office there. Buyers should ask for wire-to-water performance over the expected annual load distribution, not only hydraulic efficiency at one point. A vertical in-line layout can save floor area, but the design must still demonstrate pipe-load limits, vibration control, lifting access and isolation for motor or seal replacement. The public HKG10 material does not disclose installed pump models, tonnage, commissioning data or current operating efficiency. Procurement should require controls-point lists, cybersecurity and network ownership, failure and restart sequences, spare-drive strategy and performance guarantees tied to stated water temperatures, glycol percentage and sensor accuracy. → Armstrong Fluid Technology supplies pumps and plant controls. It does not supply server cold plates or rack manifolds. Its vertical in-line design aims to cut plant-room floor and pipe needs. Design Envelope versions add variable-speed controls and data links. Armstrong also packages full chilled-water plant rooms. Its Digital Realty HKG10 case documents that role. A package can reduce work in the field. Buyers must still separate package results from the stated limits of one pump line. Selection needs the project flow, head and fluid data. It also needs motor efficiency, the control plan, N+1 backup, minimum flow and service shutoff. Factory tests should be witnessed. Armstrong was founded in Toronto in 1934 and keeps its head office there. Buyers should ask for wire-to-water results over the expected yearly load, not one best point. A vertical in-line layout can save floor area. The design must still prove pipe-load limits, low vibration, lift access and shutoff for motor or seal work. The public HKG10 case does not name the pump models or plant tonnage. It gives no start-up data or current efficiency. Buyers should require a controls-point list and clear network ownership. They should also set cyber rules, failure and restart steps, a spare-drive plan and firm test points. Those points must state water temperature, glycol share and sensor accuracy.
  • Belimo description: Belimo supplies hydronic control devices, not complete cooling loops. Its Energy Valve combines a pressure-independent valve, ultrasonic flow measurement, temperature sensors and control logic; EPIV provides electronic pressure-independent flow control without the same energy-metering feature set. Belimo explicitly positions these devices for coolant distribution units, cold plates, rear-door exchangers, two-phase condensers, computer-room air handlers and fan walls. Buyers must size the valve for the real flow range and available differential pressure, then verify glycol correction, sensor accuracy, fail position, network integration and cybersecurity. A large valve that spends most of its life near minimum controllable flow can undermine the promised control quality. Belimo was founded in 1975, is headquartered in Hinwil and is listed on the SIX Swiss Exchange. The controls narrative should specify whether the building system commands position, flow, differential pressure or thermal power, and what local fallback applies after communications loss. Commissioning should verify meter accuracy with the actual glycol concentration, straight-pipe conditions and temperature-sensor placement. Public pages do not disclose long-duration data-center failure rates or one standard configuration for every rack loop; Belimo directs liquid-cooling users to its data-center team. Buyers should also define firmware management, credential ownership, cloud connectivity, trend retention, alarm routing, actuator replacement and how valve data is reconciled with CDU and facility meters. → Belimo supplies water-loop controls, not full cooling loops. Its Energy Valve joins a pressure-independent valve with an ultrasonic flow meter. It also has heat sensors and control logic. The EPIV controls flow as system pressure changes. It does not have the same energy-meter features. Belimo lists these devices for coolant distribution units, cold plates and rear-door heat exchangers. It also lists two-phase condensers, computer room air handlers and fan walls. Buyers must size each valve for the real flow range and available pressure. They should then check glycol correction, sensor accuracy, fail position, network links and cyber risks. An oversized valve may spend most of its life near the lowest flow it can control. That can weaken control quality. Belimo was founded in 1975. It is based in Hinwil and listed on the SIX Swiss Exchange. The control plan should say what the building system commands. That may be position, flow, pressure difference or heat transfer. It should also state the local fallback after a link fails. Start-up tests should use the real glycol mix. They should check meter accuracy, straight pipe and sensor placement. Public pages do not give long-term data-center failure rates or one setup for every rack loop. Belimo tells liquid-cooling users to contact its data-center team. Buyers should set rules for firmware, passwords, cloud links, saved trends, alarms and actuator swaps. They should also state how valve data is checked against coolant distribution unit and plant meters.
  • Wieland description: Wieland's electronics-cooling business supplies cold plates rather than complete data-center loops. Its standard 4000-series plates use friction-stir-welded construction and Micro Deformation Technology pin-fin fields; custom programs can change the footprint and internal geometry for a particular heat map. The linked products are general thermal interfaces, not evidence of qualification for a named CPU, GPU or server. Buyers should provide the actual component package, heat flux, mounting load, inlet temperature, allowable pressure drop, coolant chemistry and leak-test requirement, then assign responsibility for hoses, quick disconnects and the rack manifold. Published drawings are useful for mechanical screening but do not replace a thermal validation report. Wieland was founded in Ulm in 1820 and remains headquartered there. A qualification plan should include thermal mapping, flow distribution, pressure cycling, proof and burst tests, corrosion exposure, flatness after joining and inspection of the friction-stir weld. The public drawings do not state heat capacity, thermal resistance, pressure drop, proof pressure or the complete wetted-material stack for the two linked parts. Buyers should ask which dimensions are standard versus customizable, what design change triggers requalification, and whether serial traceability and cleanliness certificates accompany production units. Server warranty, mounting hardware and interface-material responsibility must also be assigned explicitly. → Wieland's electronics-cooling unit supplies cold plates, not full data-center loops. Its standard 4000-series plates use friction-stir welds and Micro Deformation Technology pin fins. A custom program can change the plate size and inner flow path for a given heat map. The linked products are broad heat-transfer parts. They are not proof of approval for a named processor, graphics chip or server. Buyers should provide the real chip package and heat flux. They should also state the mount load, inlet temperature, allowed pressure drop, coolant and leak-test rule. The contract must assign ownership of hoses, quick disconnects and the rack manifold. Product drawings help screen fit. They do not replace a heat test. Wieland was founded in Ulm in 1820 and is still based there. A test plan should map heat and flow. It should include pressure cycles, proof and burst tests, corrosion exposure and flatness after joining. It should also inspect the friction-stir weld. Public drawings do not state heat capacity, thermal resistance, pressure drop or proof pressure. They do not give the full wetted-material list for these two parts. Buyers should ask which sizes are fixed and which can change. They should define which design changes force a new test. Ask whether shipped units include serial records and cleanliness proof. The parties must also assign the server warranty, mounting hardware and interface material.
  • Valvoline Global Operations description: Valvoline Global Operations has extended its automotive and industrial fluid business into data-center thermal management under the Beyond by Valvoline name. The cited portfolio identifies an HTF-DE1 dielectric immersion fluid and PG25 Advanced heat-transfer fluid for direct-to-chip and heat-exchange loops. Valvoline also publishes an 18-month validation with Iceotope hardware, HPE servers, and NVIDIA A40 graphics processors. That test is useful evidence of one fluid-hardware combination, but its 5.2 kW test load is not a rack-scale capacity demonstration and does not qualify other servers or materials. Product availability varies by region, and the public portfolio page does not disclose full chemistry, inhibitor package, service life, concentration tolerances, or a complete list of approved wetted materials. Procurement should obtain the current product and safety sheets, fluid-quality limits, fill and sampling procedure, compatibility approvals, warranty terms, contamination thresholds, corrective actions, storage life, and recovery or disposal route. The company is an Aramco affiliate; it is separate from the publicly traded Valvoline retail-services business. HTF-DE1 and PG25 Advanced serve different architectures and should not share one generic fluid specification, sampling limit, or spill procedure. Buyers should also establish which Valvoline Global legal entity supplies the fluid, where retained reference samples will be stored, whether laboratory interpretation is included, and how a result outside limits is divided among the fluid supplier, cooling-system vendor, and server manufacturer. → Valvoline Global Operations has moved its fluid work into data-center cooling. It sells these products under the Beyond by Valvoline name. The cited range has two different fluids. HTF-DE1 is a dielectric fluid for immersion. PG25 Advanced serves direct-to-chip and heat-exchange loops. Valvoline also reports an 18-month test with Iceotope hardware. The test used HPE servers and NVIDIA A40 graphics processors. It proves one fluid and hardware mix. Its 5.2 kW load does not prove rack-scale capacity. It also does not qualify other servers or materials. Product supply varies by region. The public page omits the full chemistry and inhibitor pack. It also omits service life, dose tolerance, and a full list of approved wet materials. Buyers need current product and safety sheets. They need fluid limits, fill steps, and sample steps. The bid should include material approvals, warranty terms, dirt limits, fixes, storage life, and the final waste route. The company is an Aramco affiliate. It is not the public Valvoline retail business. HTF-DE1 and PG25 Advanced serve different cooling designs. They should not share one fluid rule, sample limit, or spill plan. Buyers must name the Valvoline legal entity that supplies each fluid. They should state where sealed baseline samples will be held. Lab review may or may not be part of the sale, so the contract must say. It must also divide action after a bad result among Valvoline, the cooling vendor, and the server maker.
  • Ecolab description: Ecolab, through Nalco Water, supplies chemistry, controllers, monitoring, remote support, and field service for cooling-water systems. Its data-center portfolio spans open cooling towers, adiabatic heat rejection, and direct-to-chip loops. The linked products show the facility-water side: 3D TRASAR Cooling Water combines chemistry and monitoring for towers and chillers, while the adiabatic program adds unit-level conductivity and flow measurement, centralized dosing, alarms, and digital records. Ecolab also owns CoolIT Systems, but this record describes Ecolab's water-management offer rather than duplicating CoolIT's cooling hardware. Buyers should define one water specification across equipment vendors, including pH, conductivity, chlorides, hardness, corrosion, microbiological control, suspended solids, sampling methods, alarm and action limits, and authority to dose or drain. They should also separate supplier-reported savings from guaranteed project outcomes: results depend on source water, metallurgy, heat flux, cycles of concentration, weather, and operating discipline. Public product pages do not state a universal chemical formulation, installed price, sensor calibration interval, data-retention term, or service response commitment. Open-tower treatment, adiabatic-media treatment, and a closed technology loop have different contamination and warranty boundaries; an Ecolab master agreement should not collapse them into one program. Procurement should name the approved laboratory methods, baseline samples, reporting frequency, data export format, escalation contacts, included site visits, consumable replenishment, and the party authorized to change dose or blowdown setpoints. → Ecolab, through Nalco Water, supplies chemistry and controls for cooling water. It also offers monitoring, remote support, and field service. Its data-center work spans open towers, adiabatic heat rejection, and direct-to-chip loops. The linked products cover the facility-water side. 3D TRASAR Cooling Water joins chemistry with monitoring for towers and chillers. The adiabatic program adds conductivity and flow checks for each unit. It also adds central dosing, alarms, and digital records. Ecolab owns CoolIT Systems. This record covers Ecolab's water service, not CoolIT's cooling hardware. Buyers need one water specification that all equipment vendors accept. It should set limits for pH, conductivity, chlorides, hardness, corrosion, microbes, and suspended solids. It should also name sample methods and alarm limits. The contract must say who may dose or drain the system. Supplier-reported savings are not a project guarantee. Results depend on source water, metals, heat flux, tower cycles, weather, and sound operating practice. Public pages give no standard chemical formula or installed price. They also omit sensor calibration terms, data retention, and service response times. Open towers, adiabatic media, and closed technology loops have different risks and warranty limits. One master agreement must keep those programs distinct. It should name the approved lab methods and baseline samples. It should set report timing and data export rules. It should list escalation contacts, site visits, and consumable supply. It must also name who may change dose or blowdown settings.
  • Siemens description: Siemens supplies data-center power, building automation, fire safety, security, and cooling controls through its Smart Infrastructure business. This record focuses on two current control layers. Desigo PXC4 is a programmable automation-station family for mechanical equipment and building systems. White Space Cooling Optimization uses dense temperature sensing and predictive software to adjust data-hall cooling to information-technology load. The two products solve different problems: PXC4 executes plant and equipment sequences, while White Space Cooling Optimization models airflow and supervises room cooling. Siemens publishes a named Novva Data Centers reference in Colorado Springs where Desigo PXC controllers were installed in a flat architecture across chillers, cooling towers, pumps, and fans. Siemens reports no cooling downtime for a year and a half and material energy savings, but those results include rewiring, reprogramming, and a broader shift in cooling strategy. Buyers should require a complete point list, sequence of operation, failure matrix, local fallback, sensor calibration plan, network architecture, access controls, software and cloud terms, patching responsibilities, trend retention, and witnessed tests for power loss, communication loss, bad sensors, and rapid compute-load changes. Public sources do not disclose Novva's IT capacity, installed controller count, project price, or independently audited savings. Procurement should also separate the local safety sequence from supervisory optimization and state which functions must continue without a Siemens server, cloud service, or wide-area connection. The contract should include editable control logic, current backups, rollback procedures, license renewal terms, and ownership of integration work when chillers or room-cooling units come from other manufacturers. → Siemens supplies power and building controls for data centers. It also sells fire, security, and cooling systems through Smart Infrastructure. This record covers two control layers. Desigo PXC4 is a set of programmable building controllers. White Space Cooling Optimization uses many temperature sensors and forecast software. It adjusts room cooling to the information-technology load. The products have different jobs. PXC4 runs plant and equipment steps. White Space Cooling Optimization maps air flow and guides room cooling. Siemens has a named Novva Data Centers case in Colorado Springs. Desigo PXC controllers use a flat design there. They control chillers, towers, pumps, and fans. Siemens reports no cooling downtime for a year and a half. It also reports large power savings. The work included new wires, new control code, and a wider cooling change. The controller alone did not create every result. Buyers need a full point list and sequence. They need a fault plan and a safe local mode. The design should cover sensor checks, networks, access, software, cloud terms, patches, and trend storage. Tests should cut power and links. They should also inject bad sensor values and fast compute-load changes. Public sources omit Novva's information-technology capacity and controller count. They also omit price and an outside audit. Local safety logic must remain distinct from high-level control. The contract must state what runs without a Siemens server, cloud service, or wide-area link. Buyers also need editable logic, current backups, a rollback plan, license terms, and clear ownership of third-party equipment links.
  • Pall Corporation description: Pall Corporation designs filtration, separation, and purification equipment across industrial and life-science markets. The two linked records are relevant to data-center facility water because Pall explicitly lists cooling water and pre-reverse-osmosis service, but Pall's public pages do not present them as qualified technology-cooling-loop filters. Ultipleat High Flow housings address large facility flows; Profile UP cartridges offer a broad range of particle-removal grades. A buyer should not transfer a generic cooling-water rating into a cold-plate loop without checking absolute efficiency or beta ratio, dirt-holding capacity, clean and terminal pressure drop, bypass behavior, element collapse pressure, seals, extractables, fluid compatibility, and the smallest protected channel. Installation design must define commissioning flush filtration, permanent full-flow or side-stream duty, isolation, differential-pressure alarms, safe element change, spare inventory, and disposal. Pall publishes detailed construction and flow information, but no cited data-center deployment, server-loop validation, installed price, or service-life result. Pall is a wholly owned Danaher subsidiary; product availability and exact configurations should be confirmed for the project region. Procurement should qualify the housing, cartridge, seal, and fluid as one assembly and prohibit unreviewed replacement elements that merely fit dimensionally. It should distinguish temporary construction-debris removal from permanent polishing, define the permitted bypass state, require clean and loaded pressure-drop calculations, and specify how operators will avoid contaminating the clean side while opening a housing beside live cooling loads. → Pall Corporation makes filters and separation equipment for many industrial markets. The two linked records can serve facility water. Pall lists cooling water and treatment before reverse osmosis as uses. Its public pages do not qualify these products for a technology cooling loop. Ultipleat High Flow housings handle large flows. Profile UP cartridges offer many particle-removal grades. A generic cooling-water rating is not enough for a cold-plate loop. Buyers need the filter efficiency and its test basis. They need dirt capacity and clean pressure drop. They also need the final pressure drop, bypass action, collapse limit, seal data, extractables, and fluid fit. The smallest protected channel sets a key limit. The design must define filtration during the first flush. It must then state whether the permanent filter is full flow or side stream. Isolation, pressure alarms, safe element changes, spare stock, and waste handling also need clear plans. Pall gives detailed build and flow data. It gives no cited data-center deployment or server-loop test. Installed price and field service life are also unknown. Pall is a Danaher subsidiary. Buyers should confirm local supply and the exact build. The housing, cartridge, seal, and fluid must qualify as one set. A replacement that merely fits is not proven. Temporary debris removal is not the same as long-term polishing. The bid should state when bypass is allowed. It should show pressure loss with a clean and a loaded filter. The change method must keep dirt off the clean side near live cooling loads.
  • Kurita Water Industries description: Kurita Water Industries supplies industrial water-treatment chemicals, equipment, monitoring, and service. Its cooling portfolio covers open towers, closed cooling and chilled-water circuits, make-up water, corrosion, scale, fouling, and microbiological control. The linked S.sensing MX platform monitors cooling-water parameters and can control dosing based on measured active product concentration. The linked Korrodex range covers corrosion inhibitors, hardness stabilizers, and antifreeze products for closed systems. These are product families rather than one universal formulation or bill of materials. A data-center buyer needs a site-specific program based on source water, loop type, metallurgy and polymers, oxygen ingress, temperature, heat flux, discharge rules, and every connected equipment warranty. Required submittals include chemical identity and concentration, compatibility, sample points, methods and frequency, calibration, alarm and action limits, authority to dose or drain, data access, cybersecurity, and emergency remediation. Kurita's public sources do not provide a named data-center deployment for these two records, a universal performance guarantee, or pricing. Generic industrial cooling experience should therefore be verified against the specific facility and technology loop. Buyers should ask Kurita to map each proposed analyzer and chemical to a stated failure mode, test method, alert limit, corrective action, and equipment warranty. The service schedule should identify local laboratory capability, calibration standards, reagent and spare-sensor lead times, remote-monitoring retention, escalation coverage, and what happens when an analyzer is unavailable but cooling must continue. → Kurita Water Industries supplies water chemicals, equipment, monitoring, and service. Its cooling work covers open towers and closed chilled-water loops. It treats make-up water and addresses rust, scale, fouling, and microbes. The S.sensing MX platform checks cooling-water conditions. It can control dose from a measured level of active treatment product. Korrodex is a range for closed systems. It includes rust control, hardness control, and antifreeze products. These are product families, not one formula or fixed bill of materials. A data center needs a program made for its own water and loop. The review must cover all metals and polymers. It must address air entry, temperature, heat flux, discharge rules, and each equipment warranty. The submittal should name the chemical and dose. It should state material fit and sample points. It should give test methods, test timing, and calibration steps. Alert limits and action limits must be clear. The contract must say who may dose or drain. It also needs data access, cyber rules, and an emergency plan. Kurita gives no named data-center use for these two records. It gives no standard guarantee or price. Its wider industrial record still needs a site test. Each sensor and chemical should link to a known failure mode. The plan should name the test, alert, fix, and warranty at risk. It should state local lab support and calibration standards. Reagent and spare-sensor lead times matter. So do data retention and escalation cover. The site also needs a safe mode when an analyzer is down but cooling must run.
  • Veolia Water Technologies description: Veolia Water Technologies provides water-treatment equipment, chemistry, controls, digital monitoring, and operating services. For data-center cooling, its public material covers source-water treatment, open recirculating cooling systems, reclamation, and reuse. The linked E.C.O.Film program uses non-phosphorus chemistry for scale and corrosion control, while the TrueSense Ready-Set-Go controller monitors pH, oxidation-reduction potential, conductivity, and, in supported programs, chemical levels. A published Illinois data-center case reports higher cooling-tower cycles and lower water use after adding pH control, acid feed, remote monitoring, and alarms. That result is supplier-reported, the operator is unnamed, and it does not isolate the controller from the full treatment program. Buyers should require a water balance, chemistry model, materials review, dosing and containment design, sample and calibration plan, alarm response, cyber and data terms, discharge assessment, and measurable acceptance criteria. They should also identify whether the contracting party is Veolia Water Technologies, Veolia Water Technologies & Solutions, or a regional affiliate. Public sources do not disclose the Illinois site's capacity, location beyond the state, contract value, or independent audit. The proposal should state which regional Veolia entity supplies chemicals, owns controller configuration, interprets alarms, and attends an excursion. Procurement should require the modeled starting conditions, accepted water-quality range, baseline and verification period, data export, consumables, laboratory methods, acid-handling safeguards where relevant, and a remedy if treatment targets are missed without compromising cooling availability. → Veolia Water Technologies supplies water-treatment equipment, chemicals, controls, and digital monitoring. It also offers operating services. Its data-center material covers source water and open cooling loops. It also covers water recovery and reuse. E.C.O.Film uses chemistry with no phosphorus to control scale and rust. The TrueSense Ready-Set-Go controller checks pH, oxidation-reduction potential, and conductivity. It can also check chemical levels in supported programs. An Illinois case reports more tower cycles and less water use. The work added pH control, acid feed, remote checks, and alarms. Veolia reports the result, and the operator is not named. The case does not isolate the controller from the full treatment plan. Buyers need a water balance and a chemistry model. They need a review of all wet materials. The bid should show dosing, storage, spill control, samples, calibration, and alarm response. It also needs cyber terms, data rights, discharge review, and clear acceptance tests. The buyer should identify the actual contracting party. It may be Veolia Water Technologies, Veolia Water Technologies & Solutions, or a local affiliate. Public sources omit site capacity, city, contract value, and an outside audit. The proposal should name the Veolia entity that ships each chemical. It should say who owns controller settings and reads alarms. It should name who comes to site after a bad result. The bid must state the modeled starting water and the allowed quality range. It should set a baseline period and a test period. Data export, supplies, lab methods, and acid safety must be clear. The contract also needs a remedy if treatment misses its targets while cooling must stay online.

  • Smardt Chiller Group description: Smardt designs air-cooled, water-cooled, evaporatively cooled, and modular chillers around oil-free centrifugal compressors. Its Core and Ultra water-cooled ranges cover plant sizes from 45 to 3,600 refrigeration tons, while multi-compressor layouts provide staged capacity and some compressor-level redundancy. For a data-center procurement, the useful distinction is specialization: Smardt can engineer the chiller package, but pumps, towers or dry coolers, controls, and rack-side equipment still require a complete plant design. Buyers should obtain project-specific selections at the required chilled- and condenser-water temperatures, annual load calculations, refrigerant and service plans, restart behavior, and witnessed performance tests rather than extrapolating from range limits. → Smardt designs air-cooled, water-cooled, evaporatively cooled, and modular chillers around oil-free centrifugal compressors.

Buyers should obtain project-specific selections at the required chilled- and condenser-water temperatures, annual load calculations, refrigerant and service plans, restart behavior, and witnessed performance tests rather than extrapolating from range limits. Qualification should separate compressor redundancy from whole-chiller and whole-plant redundancy: continued operation after one compressor stops does not establish capacity after loss of a vessel, power feed, controller, pump, or condenser-water path. The public range pages also do not disclose delivered pricing, lead time, fleet-wide failure rates, or one standard efficiency valid across all configurations. Tender documents should therefore identify the exact model, rating standard, ambient and water design points, fouling assumptions, part-load sequence, allowable downtime, spare-parts commitment, and party responsible for integrated plant controls.
  • Baltimore Aircoil Company description: Baltimore Aircoil Company, commonly called BAC, makes outdoor heat-rejection equipment rather than server-side liquid loops. Its data-center range includes the TrilliumSeries dry cooler and the HXV hybrid cooler, allowing a plant designer to trade footprint, fan energy, and peak water use against required leaving-fluid temperature. BAC reports operating since 1938 and describes itself as employee-owned, with product and service coverage across multiple regions. Buyers should compare units at site-specific summer design conditions, glycol concentration, altitude, sound limits, redundancy, and water-quality assumptions, and should require fan power, pressure drop, plume behavior, controls integration, and maintenance access in the submittal. → Baltimore Aircoil Company, commonly called BAC, makes outdoor heat-rejection equipment rather than server-side liquid loops.

Buyers should compare units at site-specific summer design conditions, glycol concentration, altitude, sound limits, redundancy, and water-quality assumptions, and should require fan power, pressure drop, plume behavior, controls integration, and maintenance access in the submittal. The two linked products represent materially different utility and operating obligations. A dry cooler avoids routine evaporation but loses temperature margin as outdoor dry-bulb temperature rises; the HXV can use evaporation to extend performance but introduces water treatment, discharge, drift, hygiene, and winterization work. Public product pages do not provide a universal annual energy or water result. A procurement team should require hourly climate modeling, explicit mode-change logic, design-day derating after a fan or pump failure, basin and coil freeze protection, sound at day and night setpoints, and confirmation that service clearances fit the proposed roof or yard layout.
  • EVAPCO description: EVAPCO supplies facility-side heat rejection for data centers, including the eco-Air family of dry coolers and larger field-erected configurations. The EAW-HD APEX and EAW-DD Double Stack products target high heat rejection per unit of plan area while operating without routine evaporation. EVAPCO publishes CTI-certified ratings for selected dry-cooler lines and offers controls and factory assembly, but those facts do not establish site capacity without a thermal selection. Procurement should test performance at actual entering and leaving fluid temperatures, peak dry-bulb conditions, glycol concentration, elevation, recirculation, sound restrictions, fan-failure cases, and the required plant redundancy. → EVAPCO supplies facility-side heat rejection for data centers, including the eco-Air family of dry coolers and larger field-erected configurations.

CTI certification and a thermal performance guarantee address defined rating conditions; they do not answer whether a roof arrangement will recirculate hot discharge air or whether the plant can meet outlet temperature after a cell, power feed, or control panel is unavailable. The public sources also do not disclose installed cost, delivery schedule, annual fan energy, or maintenance staffing for a particular site. Buyers should request the selection printout, test code and tolerance, fan-by-fan electrical schedule, minimum stable speed, controls points, coil-cleaning method, corrosion treatment, freeze strategy, lifting plan, structural reactions, and a layout review using the actual surrounding buildings and prevailing winds.
  • Güntner description: Güntner manufactures finned-coil heat exchangers and dry coolers for refrigeration, process, HVAC, and information-technology loads. Its Flat and V-shape VARIO families can be configured with different coils, fans, controls, materials, and sound treatments; the V-shape line can also add hydroBLU adiabatic pre-cooling. Published data-center cases show the equipment rejecting heat from immersion systems, which is evidence of a facility-side role rather than server compatibility. Buyers should require a project selection that accounts for hottest-hour ambient conditions, glycol, fouling, elevation, fan staging, acoustic limits, hot-air recirculation, freeze protection, water use when adiabatic assistance is fitted, and capacity after a fan or control failure. → Güntner manufactures finned-coil heat exchangers and dry coolers for refrigeration, process, HVAC, and information-technology loads.

Configuration breadth means a family name alone is not a comparable bid. Coil geometry, circuiting, metallurgy, fan quantity, motor type, controls, coatings, and adiabatic accessories can change capacity, pressure drop, sound, water demand, footprint, and service procedure. Procurement should lock those choices to a scheduled duty and require performance at normal, peak, minimum-load, and failure conditions. It should also identify who supplies pumps, expansion and air separation, intermediate heat exchangers, water treatment for any assisted mode, structural steel, and supervisory controls, because the dry cooler does not by itself define or warrant the complete heat-rejection system.
  • Vahterus description: Vahterus designs gasket-free Plate & Shell Heat Exchangers around welded circular plate packs inside pressure shells. The architecture can isolate fluids in cooling, condensing, evaporating, and heat-recovery duties and is custom selected rather than sold on one universal megawatt rating. The company publishes nine plate sizes, including the PSHE 7 and PSHE 9 represented in this batch, but nozzle and surface-area ranges are not substitutes for a thermal calculation. Data-center buyers should specify both fluids, flow rates, supply and return temperatures, allowable approach temperature and pressure drop, fouling allowance, design pressure, metallurgy, cleanability, leak detection, isolation, bypass, and local pressure-vessel certification. → Vahterus designs gasket-free Plate & Shell Heat Exchangers around welded circular plate packs inside pressure shells.

A fully welded exchanger removes plate-pack gaskets from the design, but that construction also affects inspection, mechanical cleaning, repair, and capacity expansion. Buyers should ask how the selected unit will be cleaned for the stated fluids, what fouling or plugging evidence triggers intervention, whether an openable or fully welded execution is proposed, and how an internal leak between circuits would be detected. The public size table does not disclose data-center references, prices, lead times, thermal guarantees, or standard spare strategy. Final qualification needs certified calculations, fabrication drawings, code documentation, weld inspection requirements, nozzle loads, vent and drain provisions, support design, and an isolation arrangement that permits service without losing the required cooling duty.
  • SWEP description: SWEP manufactures brazed plate heat exchangers used as loop separators in data-center free cooling, coolant distribution units, mechanical cooling, and heat-reuse systems. Its B439 and B649 products have direct company-documented use in Infosys data centers, where they separate cooling-tower water from a cleaner internal loop. Brazed construction offers a compact sealed assembly, but it changes inspection, cleaning, repair, and end-of-life choices compared with gasketed plate-and-frame equipment. Buyers should require a thermal selection for fluid chemistry, duty temperatures, flow, approach, pressure drop, fouling, material compatibility, design pressure, parallel-unit balancing, isolation, cross-contamination detection, and replacement access. → SWEP manufactures brazed plate heat exchangers used as loop separators in data-center free cooling, coolant distribution units, mechanical cooling, and heat-reuse systems.

The public sources do not state the exact plate count, brazing alloy, pressure loss, approach temperature, water analysis, cleaning history, or measured energy savings for every installed unit. Procurement should identify the precise article number and manufacturing configuration, establish strainers and water-quality limits, specify clean and fouled guarantees, and decide whether several isolated exchangers are needed for maintainability and fault tolerance. It should also document chemical-cleaning compatibility, flushing connections, lifting and replacement space, leak-monitoring method, and the party responsible for hydraulic balancing when units operate in parallel.
  • MITA Group description: MITA Group covers plant-side thermal equipment through specialist businesses including MITA Cooling Technologies in Italy and TORRAVAL Cooling in Spain. MITA Cooling Technologies makes factory-assembled open- and closed-circuit evaporative towers, while TORRAVAL designs larger and customized towers such as the CTFP units documented at a Barcelona data-processing center. This portfolio makes the group relevant where a data-center designer must choose between direct-contact tower water and a closed process loop, but it does not remove the need for project-specific plant engineering. Buyers should compare thermal duty at the site's wet-bulb conditions, annual and peak water use, fan and pump energy, drift, plume, water treatment and discharge, hygiene controls, sound, redundancy, materials, winter operation, access, controls integration, factory or field assembly, and local service. → MITA Group covers plant-side thermal equipment through specialist businesses including MITA Cooling Technologies in Italy and TORRAVAL Cooling in Spain.

Contracting boundaries need particular attention because the linked products carry MITA and TORRAVAL brands within the same group. A tender should identify the legal seller, manufacturing site, thermal guarantor, controls supplier, commissioning party, and organization responsible for warranty and long-term service in the project country. The Barcelona case confirms a sixteen-tower project but withholds the operator, thermal schedule, measured utilities, and acceptance results. Buyers should therefore ask for a comparable reference at the proposed scale and climate, the certified selection and test tolerance, expected cycles of concentration and blowdown, drift and plume controls, basin and coil cleaning procedures, legionella management responsibilities, and capacity after the largest credible equipment or utility failure.
  • Mitsubishi Heavy Industries Thermal Systems description: Mitsubishi Heavy Industries Thermal Systems sells centrifugal chillers from 150 to 6,000 refrigeration tons across its published portfolio. The ETI-Z and GART-ZE/ZEI ranges use low-global-warming-potential HFO refrigerants and cover different plant scales, with inverter options available. The company identifies data centers as an application and names Shirakawa Data Center, but its public application page does not disclose installed model, quantity, capacity, efficiency, or commissioning date, so this batch does not create a deployment record from that reference. Buyers should require project-specific full- and part-load selections, chilled- and condenser-water limits, refrigerant availability, harmonic and starting-current data, restart sequence, redundancy, tube-cleaning access, controls integration, service coverage, and witnessed factory testing. → Mitsubishi Heavy Industries Thermal Systems sells centrifugal chillers from 150 to 6,000 refrigeration tons across its published portfolio.

A published refrigeration-ton range cannot answer how many machines a resilient plant needs or how they behave as the information-technology load ramps. Qualification should include the selected compressor and drive arrangement, minimum stable load, surge-control method, condenser-water reset envelope, efficiency at each planned staging point, and derating after a compressor, chiller, pump, or cooling-tower cell fails. The public pages do not provide commercial terms, lead times, fleet reliability, data-center acceptance results, or regional parts commitments. Those unknowns should be resolved through the bid schedule, factory-test protocol, reference calls, refrigerant supply plan, preventive-maintenance scope, and guaranteed emergency response time.
  • Mitsubishi Electric Hydronics & IT Cooling Systems description: Mitsubishi Electric Hydronics & IT Cooling Systems, or MEHITS, designs applied cooling for comfort, industrial processes, and information-technology facilities. Its portfolio joins Climaveneta air- and water-cooled chillers with RC critical-cooling equipment, including free-cooling chillers designed specifically for hyperscale and colocation data centers. The two products in this batch represent oil-free centrifugal and inverter-screw air-cooled approaches, not interchangeable selections. Buyers should compare annual energy at their water temperatures and climate, compressor and fan redundancy, free-cooling switchover, glycol strategy, fast restart, refrigerant regulation, heat left in room air, sound, controls, maintainability, factory acceptance testing, and service capability in the project country. → Mitsubishi Electric Hydronics & IT Cooling Systems, or MEHITS, designs applied cooling for comfort, industrial processes, and information-technology facilities.

The product relationship establishes available chiller families, not responsibility for the rack-side loop, room air handlers, pumps, electrical infrastructure, or outdoor layout around each unit. Procurement should define those interfaces and require an annual simulation using the site's weather file, phased load profile, supply and return temperatures, glycol concentration, and required reserve. It should also test transition among mechanical, hybrid, and free-cooling modes, capacity during a circuit or fan failure, restart after power loss, low-load stability, control points and data ownership, coil-cleaning access, winter protection, and the availability of trained technicians and refrigerant in the operating region.
  • CPC description: CPC, or Colder Products Company, is a component supplier rather than a complete rack-cooling integrator. Its Everis range covers latched and blind-mate quick disconnects from server-level connections toward larger rack-loop interfaces, with OCP-oriented UQD models intended to support multi-sourcing. Buyers should select the exact flow size, termination, seal, pressure and coolant combination; a compatible envelope does not establish equal pressure drop, spillage or lifecycle performance across suppliers. CPC publishes useful wetted-material and connection data, but a project submittal should still define cleanliness, mating-cycle testing, allowable side load, replacement policy and responsibility for the assembled hose. The company was founded in Minnesota in 1978, is headquartered in Arden Hills and operates within Dover. → CPC, or Colder Products Company, is a component supplier rather than a complete rack-cooling integrator. Its Everis range covers latched and blind-mate quick disconnects from server-level connections toward larger rack-loop interfaces, with OCP-oriented UQD models intended to support multi-sourcing. Buyers should select the exact flow size, termination, seal, pressure and coolant combination; a compatible envelope does not establish equal pressure drop, spillage or lifecycle performance across suppliers. CPC publishes useful wetted-material and connection data, but a project submittal should still define cleanliness, mating-cycle testing, allowable side load, replacement policy and responsibility for the assembled hose. The company was founded in Minnesota in 1978, is headquartered in Arden Hills and operates within Dover. Procurement should also ask whether CPC or the hose assembler warrants the finished assembly, which inspection records accompany each lot, and whether socket and plug revisions remain backward compatible. Public product pages do not disclose a fleet-wide field-failure rate, a standard preventive-replacement interval, or the complete qualification evidence behind every coolant combination. Those unknowns matter because a nominally interchangeable connector can still differ in insertion force, residual spill, internal volume and pressure loss. A rack mock-up should therefore test access, labeling, connection confirmation and technician removal while adjacent branches remain live.
  • Stäubli description: Stäubli supplies connection hardware within the liquid loop, not the pumps, cold plates or facility heat rejection around it. Its data-center portfolio includes OCP-oriented UQD and blind-mate UQDB couplings as well as the CGD metal range used by Fujitsu in Fugaku. The published ranges cover several nominal diameters, seal choices and alignment formats, so procurement must identify a complete socket-and-plug combination rather than cite only a family name. Buyers should compare pressure loss at the required flow, drip and air-inclusion limits, allowable misalignment, mating cycles, coolant compatibility and whether a listed approval applies to the exact part number. Founded in 1892, Stäubli remains family owned and is headquartered in Pfäffikon, Switzerland. → Stäubli supplies connection hardware within the liquid loop, not the pumps, cold plates or facility heat rejection around it.

The Fugaku reference demonstrates scale and hot-swap use, but it does not publish the selected CGD size, coolant chemistry, observed leak rate or replacement history. A new buyer should request test reports for both mating halves, tolerance data for the actual blind-mate guide system, and confirmation that seals, lubricants and surface finishes comply with the server vendor's water-quality rules. The commercial review should identify regional stocking, special tooling, lot traceability and the party responsible when a coupling, hose or manifold interface causes an imbalance. Multi-source claims should be verified through cross-mating tests under pressure rather than dimensional drawings alone.
  • Parker Hannifin description: Parker Hannifin offers fluid-conveyance components from coolant-distribution units through manifolds and cold plates. The two linked distribution-manifold families are built for industrial liquid, gas, steam and hydraulic service rather than advertised as ready-made rack manifolds. They are included because they show Parker's configurable 316-stainless distribution hardware, but using one in a technology-coolant loop would require project qualification for flow balance, cleanliness, glycol chemistry, branch connections, pressure drop and service clearances. Parker separately markets OCP-oriented quick disconnects, tubing, hoses and valves for data-center liquid cooling. The broad catalog can reduce component handoffs, but it does not create a pre-qualified rack-loop assembly or a single performance warranty. Parker is headquartered in Cleveland and trades on the New York Stock Exchange. → Parker Hannifin offers fluid-conveyance components from coolant-distribution units through manifolds and cold plates.

A buyer should require Parker to identify which division owns the submitted assembly and whether the industrial manifold catalog can be adapted without invalidating data-center cleanliness or material requirements. The public sources do not publish rack dimensions, branch Cv values, internal volume, flushing procedures or an OCP qualification for HPAHM or HPAHMC. Engineering review should also resolve how isolation valves, quick disconnects, drains, vents and sensors are combined, and whether full-penetration weld and non-destructive-test records are supplied. Any proposal should name one integrator responsible for branch balancing, hydrostatic testing and warranty coordination across Parker components.
  • USystems description: USystems concentrates on close-coupled air-assisted liquid cooling. Its ColdLogik rear doors replace or attach to a rack rear door, transfer server exhaust heat to water and return near-room-temperature air without requiring processor cold plates. That can preserve standard server service procedures, but door weight, rack fit, fan interaction, condensation margin and facility-water availability remain project constraints. The linked CL20 and CL23 span medium- through very-high-density duties; their headline capacities use stated water conditions and should not be carried into a design without a project-specific coil, airflow and redundancy calculation. USystems publishes named installations at DataBank, Cambridge and other sites. It was established in 2003, operates from Bedford in the United Kingdom and is now a Legrand brand. → USystems concentrates on close-coupled air-assisted liquid cooling.

USystems publishes named installations at DataBank, Cambridge and other sites. It was established in 2003, operates from Bedford in the United Kingdom and is now a Legrand brand. Buyers should request capacity tables across inlet-water temperatures, server airflow and altitude, together with fan power, water-side pressure loss, sound and failure-mode data. A retrofit survey should confirm hinge loads, cabinet adapter frames, aisle clearance, hose bend radius, leak detection and how a loaded door is supported during server service. Public references do not disclose standardized installed cost, fleet-wide fan or valve failure rates, or current measured annual efficiency. Contracts should state whether USystems, the rack supplier or the mechanical contractor owns controls integration, condensation avoidance and cooling continuity when one door is opened or isolated.
  • Grundfos description: Grundfos operates mainly on the facility-water side of the cooling chain. Its data-center references cover split-case and end-suction pumps, controls and the MIXIT mixing-loop package used with direct-to-chip cooling at NorthC. Pump selection must be made at the actual duty point: flow, head, fluid temperature, glycol concentration, redundancy and control strategy determine energy use and whether the pump remains within an efficient operating region. The linked KPVS and NBG records illustrate two plant arrangements rather than rack-integrated pumps. Buyers should request certified curves, minimum-flow limits, motor and drive data, seal materials, service clearance, vibration criteria and a staged-control sequence. Grundfos was founded in 1945, is headquartered in Bjerringbro and is primarily owned by the Grundfos Foundation. → Grundfos operates mainly on the facility-water side of the cooling chain.

Grundfos was founded in 1945, is headquartered in Bjerringbro and is primarily owned by the Grundfos Foundation. Procurement should model the full operating map as racks are commissioned, because a pump selected for ultimate build-out may spend early years far from its best-efficiency region. The submittal should show net positive suction head margin, parallel-pump stability, motor and drive efficiency, harmonic treatment and restart behavior after a power interruption. Public case studies report project outcomes but do not provide raw trend data, standardized measurement boundaries or fleet-wide reliability. Buyers should therefore seek witnessed factory tests, recent references at comparable flow and fluid conditions, stocked critical spares and a clear division of responsibility between pump controls and the site building-automation system.
  • Armstrong Fluid Technology description: Armstrong Fluid Technology supplies pumps and plant controls rather than server cold plates or rack manifolds. Its vertical in-line architecture is intended to reduce mechanical-room floor and piping requirements, while Design Envelope variants add variable-speed controls and communications. Armstrong also packages complete chilled-water plant rooms, as documented at Digital Realty HKG10. That broader delivery can reduce field integration, but buyers should separate factory-package performance from an individual pump's published maximum envelope. Selection still requires project flow and head, fluid properties, motor efficiency, control sequence, N+1 arrangement, minimum flow, service isolation and witnessed factory testing. Armstrong was founded in Toronto in 1934 and maintains its head office there. → Armstrong Fluid Technology supplies pumps and plant controls rather than server cold plates or rack manifolds.

Buyers should ask for wire-to-water performance over the expected annual load distribution, not only hydraulic efficiency at one point. A vertical in-line layout can save floor area, but the design must still demonstrate pipe-load limits, vibration control, lifting access and isolation for motor or seal replacement. The public HKG10 material does not disclose installed pump models, tonnage, commissioning data or current operating efficiency. Procurement should require controls-point lists, cybersecurity and network ownership, failure and restart sequences, spare-drive strategy and performance guarantees tied to stated water temperatures, glycol percentage and sensor accuracy.
  • Belimo description: Belimo supplies hydronic control devices, not complete cooling loops. Its Energy Valve combines a pressure-independent valve, ultrasonic flow measurement, temperature sensors and control logic; EPIV provides electronic pressure-independent flow control without the same energy-metering feature set. Belimo explicitly positions these devices for coolant distribution units, cold plates, rear-door exchangers, two-phase condensers, computer-room air handlers and fan walls. Buyers must size the valve for the real flow range and available differential pressure, then verify glycol correction, sensor accuracy, fail position, network integration and cybersecurity. A large valve that spends most of its life near minimum controllable flow can undermine the promised control quality. Belimo was founded in 1975, is headquartered in Hinwil and is listed on the SIX Swiss Exchange. → Belimo supplies hydronic control devices, not complete cooling loops.

Belimo was founded in 1975, is headquartered in Hinwil and is listed on the SIX Swiss Exchange. The controls narrative should specify whether the building system commands position, flow, differential pressure or thermal power, and what local fallback applies after communications loss. Commissioning should verify meter accuracy with the actual glycol concentration, straight-pipe conditions and temperature-sensor placement. Public pages do not disclose long-duration data-center failure rates or one standard configuration for every rack loop; Belimo directs liquid-cooling users to its data-center team. Buyers should also define firmware management, credential ownership, cloud connectivity, trend retention, alarm routing, actuator replacement and how valve data is reconciled with CDU and facility meters.
  • Wieland description: Wieland's electronics-cooling business supplies cold plates rather than complete data-center loops. Its standard 4000-series plates use friction-stir-welded construction and Micro Deformation Technology pin-fin fields; custom programs can change the footprint and internal geometry for a particular heat map. The linked products are general thermal interfaces, not evidence of qualification for a named CPU, GPU or server. Buyers should provide the actual component package, heat flux, mounting load, inlet temperature, allowable pressure drop, coolant chemistry and leak-test requirement, then assign responsibility for hoses, quick disconnects and the rack manifold. Published drawings are useful for mechanical screening but do not replace a thermal validation report. Wieland was founded in Ulm in 1820 and remains headquartered there. → Wieland's electronics-cooling business supplies cold plates rather than complete data-center loops.

A qualification plan should include thermal mapping, flow distribution, pressure cycling, proof and burst tests, corrosion exposure, flatness after joining and inspection of the friction-stir weld. The public drawings do not state heat capacity, thermal resistance, pressure drop, proof pressure or the complete wetted-material stack for the two linked parts. Buyers should ask which dimensions are standard versus customizable, what design change triggers requalification, and whether serial traceability and cleanliness certificates accompany production units. Server warranty, mounting hardware and interface-material responsibility must also be assigned explicitly.

  • Castrol description: Castrol brings lubricant formulation, materials testing, fluid handling, and a global supply organization to data-center cooling. Its current Castrol ON range includes synthetic-hydrocarbon dielectric fluids for single-phase immersion and a separate PG 25 fluid for direct liquid cooling. This batch links only the two immersion products for which Castrol publishes direct product data. The product sheets provide useful baseline properties, but typical values are not acceptance limits and do not establish compatibility with a particular server, tank, seal, cable, or warranty. Castrol also operates an immersion research installation at its Pangbourne headquarters with Hypertec servers and Submer tanks. That is a development environment, not evidence of a production customer fleet. Buyers should require the current regional safety data sheet, batch certificate, approved-material list, fire and spill plan, storage conditions, filtration and sampling limits, end-of-life route, and written approval from the tank and server suppliers. Public sources do not disclose delivered pricing, installed fleet size, fluid life in production, or independent long-duration reliability. → Castrol brings lubricant formulation, materials testing, fluid handling, and a global supply organization to data-center cooling.

A request for quotation should lock the exact DC 15 or DC 20 formulation and revision rather than permit an unspecified Castrol ON substitute. It should also identify who owns fluid analysis after commissioning, what measured change triggers filtration or replacement, how replacement fluid will be sourced in the operating region, and whether the tank warranty remains valid after top-ups from later production batches.
  • Valvoline Global Operations description: Valvoline Global Operations has extended its automotive and industrial fluid business into data-center thermal management under the Beyond by Valvoline name. The cited portfolio identifies an HTF-DE1 dielectric immersion fluid and PG25 Advanced heat-transfer fluid for direct-to-chip and heat-exchange loops. Valvoline also publishes an 18-month validation with Iceotope hardware, HPE servers, and NVIDIA A40 graphics processors. That test is useful evidence of one fluid-hardware combination, but its 5.2 kW test load is not a rack-scale capacity demonstration and does not qualify other servers or materials. Product availability varies by region, and the public portfolio page does not disclose full chemistry, inhibitor package, service life, concentration tolerances, or a complete list of approved wetted materials. Procurement should obtain the current product and safety sheets, fluid-quality limits, fill and sampling procedure, compatibility approvals, warranty terms, contamination thresholds, corrective actions, storage life, and recovery or disposal route. The company is an Aramco affiliate; it is separate from the publicly traded Valvoline retail-services business. → Valvoline Global Operations has extended its automotive and industrial fluid business into data-center thermal management under the Beyond by Valvoline name.

The company is an Aramco affiliate; it is separate from the publicly traded Valvoline retail-services business. HTF-DE1 and PG25 Advanced serve different architectures and should not share one generic fluid specification, sampling limit, or spill procedure. Buyers should also establish which Valvoline Global legal entity supplies the fluid, where retained reference samples will be stored, whether laboratory interpretation is included, and how a result outside limits is divided among the fluid supplier, cooling-system vendor, and server manufacturer.
  • Ecolab description: Ecolab, through Nalco Water, supplies chemistry, controllers, monitoring, remote support, and field service for cooling-water systems. Its data-center portfolio spans open cooling towers, adiabatic heat rejection, and direct-to-chip loops. The linked products show the facility-water side: 3D TRASAR Cooling Water combines chemistry and monitoring for towers and chillers, while the adiabatic program adds unit-level conductivity and flow measurement, centralized dosing, alarms, and digital records. Ecolab also owns CoolIT Systems, but this record describes Ecolab's water-management offer rather than duplicating CoolIT's cooling hardware. Buyers should define one water specification across equipment vendors, including pH, conductivity, chlorides, hardness, corrosion, microbiological control, suspended solids, sampling methods, alarm and action limits, and authority to dose or drain. They should also separate supplier-reported savings from guaranteed project outcomes: results depend on source water, metallurgy, heat flux, cycles of concentration, weather, and operating discipline. Public product pages do not state a universal chemical formulation, installed price, sensor calibration interval, data-retention term, or service response commitment. → Ecolab, through Nalco Water, supplies chemistry, controllers, monitoring, remote support, and field service for cooling-water systems.

Open-tower treatment, adiabatic-media treatment, and a closed technology loop have different contamination and warranty boundaries; an Ecolab master agreement should not collapse them into one program. Procurement should name the approved laboratory methods, baseline samples, reporting frequency, data export format, escalation contacts, included site visits, consumable replenishment, and the party authorized to change dose or blowdown setpoints.
  • Xylem description: Xylem supplies the pumps and controls that move facility water through chilled-water, cooling-tower, heat-recovery, and some liquid-cooling interfaces. Its data-center brochure identifies Bell & Gossett end-suction and inline pumps, Goulds Water Technology multistage pumps, and hydrovar X smart-motor packages. The linked e-1510X and e-SV records represent two different duties: high-flow circulation and higher-head multistage service. Neither model number is a complete selection. A buyer must provide the actual flow, system curve, fluid and glycol concentration, temperature range, suction conditions, elevation, materials, redundancy philosophy, electrical service, controls, and expected turndown. Pump efficiency at the design point is not enough; phased data halls can operate at low load for years, and a standby pump only protects service if valves, power, controls, and automatic changeover are tested. Xylem publishes a named NREL deployment involving Bell & Gossett pumps and warm-water heat recovery. It does not disclose fleet-wide failure rates or guarantee that the same arrangement fits a direct-to-chip technology loop.

A complete bid should identify the selected impeller, motor, seal, coating, drive, sensors, and control firmware rather than cite only a pump family. Buyers should require certified curves with the project operating points marked, witness or documented factory testing where appropriate, minimum continuous flow, spare rotating assemblies or drive strategy, and efficiency evidence at the expected first-phase as well as ultimate load.
  • Siemens description: Siemens supplies data-center power, building automation, fire safety, security, and cooling controls through its Smart Infrastructure business. This record focuses on two current control layers. Desigo PXC4 is a programmable automation-station family for mechanical equipment and building systems. White Space Cooling Optimization uses dense temperature sensing and predictive software to adjust data-hall cooling to information-technology load. The two products solve different problems: PXC4 executes plant and equipment sequences, while White Space Cooling Optimization models airflow and supervises room cooling. Siemens publishes a named Novva Data Centers reference in Colorado Springs where Desigo PXC controllers were installed in a flat architecture across chillers, cooling towers, pumps, and fans. Siemens reports no cooling downtime for a year and a half and material energy savings, but those results include rewiring, reprogramming, and a broader shift in cooling strategy. Buyers should require a complete point list, sequence of operation, failure matrix, local fallback, sensor calibration plan, network architecture, access controls, software and cloud terms, patching responsibilities, trend retention, and witnessed tests for power loss, communication loss, bad sensors, and rapid compute-load changes. Public sources do not disclose Novva's IT capacity, installed controller count, project price, or independently audited savings. → Siemens supplies data-center power, building automation, fire safety, security, and cooling controls through its Smart Infrastructure business.

The contract should include editable control logic, current backups, rollback procedures, license renewal terms, and ownership of integration work when chillers or room-cooling units come from other manufacturers.
  • Pall Corporation description: Pall Corporation designs filtration, separation, and purification equipment across industrial and life-science markets. The two linked records are relevant to data-center facility water because Pall explicitly lists cooling water and pre-reverse-osmosis service, but Pall's public pages do not present them as qualified technology-cooling-loop filters. Ultipleat High Flow housings address large facility flows; Profile UP cartridges offer a broad range of particle-removal grades. A buyer should not transfer a generic cooling-water rating into a cold-plate loop without checking absolute efficiency or beta ratio, dirt-holding capacity, clean and terminal pressure drop, bypass behavior, element collapse pressure, seals, extractables, fluid compatibility, and the smallest protected channel. Installation design must define commissioning flush filtration, permanent full-flow or side-stream duty, isolation, differential-pressure alarms, safe element change, spare inventory, and disposal. Pall publishes detailed construction and flow information, but no cited data-center deployment, server-loop validation, installed price, or service-life result. Pall is a wholly owned Danaher subsidiary; product availability and exact configurations should be confirmed for the project region. → Pall Corporation designs filtration, separation, and purification equipment across industrial and life-science markets.

It should distinguish temporary construction-debris removal from permanent polishing, define the permitted bypass state, require clean and loaded pressure-drop calculations, and specify how operators will avoid contaminating the clean side while opening a housing beside live cooling loads.
  • Kurita Water Industries description: Kurita Water Industries supplies industrial water-treatment chemicals, equipment, monitoring, and service. Its cooling portfolio covers open towers, closed cooling and chilled-water circuits, make-up water, corrosion, scale, fouling, and microbiological control. The linked S.sensing MX platform monitors cooling-water parameters and can control dosing based on measured active product concentration. The linked Korrodex range covers corrosion inhibitors, hardness stabilizers, and antifreeze products for closed systems. These are product families rather than one universal formulation or bill of materials. A data-center buyer needs a site-specific program based on source water, loop type, metallurgy and polymers, oxygen ingress, temperature, heat flux, discharge rules, and every connected equipment warranty. Required submittals include chemical identity and concentration, compatibility, sample points, methods and frequency, calibration, alarm and action limits, authority to dose or drain, data access, cybersecurity, and emergency remediation. Kurita's public sources do not provide a named data-center deployment for these two records, a universal performance guarantee, or pricing. Generic industrial cooling experience should therefore be verified against the specific facility and technology loop. → Kurita Water Industries supplies industrial water-treatment chemicals, equipment, monitoring, and service.

The service schedule should identify local laboratory capability, calibration standards, reagent and spare-sensor lead times, remote-monitoring retention, escalation coverage, and what happens when an analyzer is unavailable but cooling must continue.
  • Veolia Water Technologies description: Veolia Water Technologies provides water-treatment equipment, chemistry, controls, digital monitoring, and operating services. For data-center cooling, its public material covers source-water treatment, open recirculating cooling systems, reclamation, and reuse. The linked E.C.O.Film program uses non-phosphorus chemistry for scale and corrosion control, while the TrueSense Ready-Set-Go controller monitors pH, oxidation-reduction potential, conductivity, and, in supported programs, chemical levels. A published Illinois data-center case reports higher cooling-tower cycles and lower water use after adding pH control, acid feed, remote monitoring, and alarms. That result is supplier-reported, the operator is unnamed, and it does not isolate the controller from the full treatment program. Buyers should require a water balance, chemistry model, materials review, dosing and containment design, sample and calibration plan, alarm response, cyber and data terms, discharge assessment, and measurable acceptance criteria. They should also identify whether the contracting party is Veolia Water Technologies, Veolia Water Technologies & Solutions, or a regional affiliate. Public sources do not disclose the Illinois site's capacity, location beyond the state, contract value, or independent audit. → Veolia Water Technologies provides water-treatment equipment, chemistry, controls, digital monitoring, and operating services. For data-center cooling, its public material covers source-water treatment, open recirculating cooling systems, reclamation, and reuse. The linked E.C.O.Film program uses non-phosphorus chemistry for scale and corrosion control, while the TrueSense Ready-Set-Go controller monitors pH, oxidation-reduction potential, conductivity, and, in supported programs, chemical levels. A published Illinois data-center case reports higher cooling-tower cycles and lower water use after adding pH control, acid feed, remote monitoring, and alarms. That result is supplier-reported, the operator is unnamed, and it does not isolate the controller from the full treatment program. Buyers should require a water balance, chemistry model, materials review, dosing and containment design, sample and calibration plan, alarm response, cyber and data terms, discharge assessment, and measurable acceptance criteria. They should also identify whether the contracting party is Veolia Water Technologies, Veolia Water Technologies & Solutions, or a regional affiliate. Public sources do not disclose the Illinois site's capacity, location beyond the state, contract value, or independent audit. The proposal should state which regional Veolia entity supplies chemicals, owns controller configuration, interprets alarms, and attends an excursion. Procurement should require the modeled starting conditions, accepted water-quality range, baseline and verification period, data export, consumables, laboratory methods, acid-handling safeguards where relevant, and a remedy if treatment targets are missed without compromising cooling availability.
