What this database is for
Move from a cooling question to a defensible decision.
DataCenterChill turns scattered supplier pages, announcements, and project evidence into records that can be checked and compared.
Compare on stated claims
Put two to four records side by side with the figure as published, the duty point it assumes, and the source behind it.
Open the workspaceVerify what is built
Separate operating sites from pilots, orders, plans, and press releases, with the source beside every claim.
Review deploymentsDownload the evidence
Normalized specification, deployment, and ownership tables as CSV and JSON, with a data dictionary and the sources behind each row.
Open the datasetsCoverage, not volume
How much of this database is decision-grade.
A thin record is still in the graph and still searchable here, but it stays out of search engines until it carries evidence. These are the figures we hold ourselves to.
- Records
- 133
- Structured, connected, and dated.
- Meeting the evidence gate
- 105
- Complete enough, sourced enough, and recently enough reviewed to be indexable.

- Normalized figures an editor has read against the source, with their duty points.
Check the work: every published edit is in the change feed, the underlying tables are in datasets, the standard behind them is the methodology, and anything wrong can be corrected with a source.

Live comparison
Coolant distribution units, as published.
| Unit | Rated capacity | Duty point | Sources |
|---|---|---|---|
| Accelsius NeuCool IR80 | 80 kW | No duty point stated | 2 |
| Accelsius MR250 | 250 kW | No duty point stated | 1 |
| CoolIT CHx2000 | 2,000 kW | No duty point stated | 1 |
Capacity figures are supplier-reported unless the record names independent evidence, and a capacity without a duty point cannot be compared with one that has it.

Cooling intelligence, not recycled headlines.
LITEON buys a quarter of DCX for about 176 million dollars
A Taiwanese power-electronics manufacturer is buying roughly 25% of the Warsaw liquid-cooling maker DCX, at a stated total transaction value of about US$176 million.
SLB agrees to buy Kelvion in a 4.1 billion dollar cooling deal
SLB will pay about 3.4 billion dollars in cash and assume about 0.7 billion of debt for the German heat-exchanger maker, buying it from Apollo-managed funds and Triton. The deal is expected to close in the first half of 2027.
nVent adds 160,000 square feet of liquid-cooling capacity
The second Blaine, Minnesota site is expected to begin production in the first half of 2027 and employ more than 200 people.
Mitsubishi Electric will build data center cooling equipment in Ohio
A new company, MEHITS US, will spend about 30 million dollars converting part of an existing Mason, Ohio plant to make cooling equipment, including coolant distribution units.
Castrol, Woodman, and Eole agree to sell immersion cooling in Japan
The three companies signed a memorandum of understanding in June to package immersion cooling for Japanese AI data centers, with deliveries planned from September 2026.
The intelligence graph
One claim should update every decision it affects.
When a project changes status, its supplier, technology, equipment, and market records change with it. That makes the database useful between news cycles, not just on publication day.

Technology
Direct-to-chip liquid cooling
A metal plate sits directly on each processor, and liquid pumped through it carries the heat out of the rack.
Scaling · Commonly selected for 50–150+ kW AI racks
Technology
Two-phase direct-to-chip cooling
The liquid on the cold plate is meant to boil. Turning to vapor is what carries the processor's heat away.
Emerging · Positioned for 80–250+ kW racks
Technology
Single-phase immersion cooling
Whole servers sit in a tank of oil-like fluid that does not conduct electricity. The fluid warms up and carries the heat away without ever boiling.
Scaling · Vendor tank ratings vary widely with water temperature and configuration
