• Smardt Chiller Groupdescription: 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 Companydescription: 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.

BAC does not publish one annual energy or water result that applies to every site. An hourly climate model should show the mode-change logic and design-day output after a fan or pump failure. The design also needs basin and coil freeze protection, separate day and night sound checks, and enough service space for the proposed roof or yard.
• EVAPCOdescription: 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. The EAW-HD APEX and EAW-DD Double Stack are intended to reject more heat in less plan area without routine evaporation. EVAPCO publishes Cooling Technology Institute-certified ratings for selected lines and offers factory assembly and controls. Capacity at a particular site still requires a thermal selection. Use the actual inlet and outlet fluid temperatures, peak outdoor dry-bulb value, glycol level, and site elevation. Review hot-air return, sound limits, fan failures, and plant backup at the same time. Certification and a thermal guarantee apply at stated rating conditions. Neither establishes whether a roof layout will draw hot discharge air back into the coils or hold outlet temperature after a cell, power feed, or panel fails. EVAPCO does not publish installed cost, delivery time, yearly fan energy, or site staffing requirements.

• Smardt Chiller Groupdescription: 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.

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.

• EVAPCOdescription: 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.
