Methodology
Named systems, explicit rating conditions and a source for every populated specification.
Research checked . 38 companies, 79 distinct source URLs.
What qualifies for the directory?
A company qualifies with a named immersion tank, immersion server or dielectric-fluid offer and at least three sourced data fields beyond its name, website and summary. Each record identifies its supply role. Rack-mounted dielectric cooling appears in the server and integration category, with the architecture explained on the company page.
The list includes Submer, GRC, LiquidStack and Asperitas. Product documentation qualifies a company; the evidence field then names its strongest pilot, validation or production deployment.
Where do the facts come from?
Sources are vendor product pages, data sheets, partner validation releases, a company prospectus and trade press, plus the Hong Kong Electrical and Mechanical Services Department’s LiquidStack trial listing. Each company page shows the source URLs and access dates. JSON maps each populated field to the source that supports it.
Research used AI assistance, and every value was checked against the source it links.
How are power figures compared?
The example-system column holds one named tank or system rating, and the rating basis gives its model, water conditions and assembly. GRC’s 368 kW figure is its ICEraQ CDU on 13°C water; DUG’s 30 kW tank is rated on a 0.9 L/s loop at 29.5°C.
Server TDP, GPU slot counts, CDU nameplate capacity and container power are excluded from the system-kW column. Fluid-property values retain the supplier’s temperature and test method. An empty cell means the supplier has not published that value for the named offer.
What does hardware evidence establish?
The hardware field names the server, GPU layout or validation platform from the source. A named validation, such as Supermicro’s Intel certification in Shell fluid, covers the exact server, fluid and tank it describes.
How are dates and corrections handled?
The access date records when a source was reviewed. The verified date records the last full review of a row. Stock, lead times and pricing come from the supplier with your quote.
Send a correction and public source to hello@immersioncoolingcompanies.com. A correction updates the affected facts and review date. Featured placement is labelled and leaves specifications, inclusion and the default alphabetical order unchanged.

Field definitions
- Supply role
- The procurement layer supplied: tank systems, servers and integration, or dielectric fluids.
- Cooling phase
- Documented immersion phase for the named offer. Both means the company sells single- and two-phase systems.
- Named offer
- The named immersion product, system or fluid grade.
- Example system (kW)
- One published tank or system rating in kW for the named model. The rating basis gives its model, size and water conditions. Server TDP and CDU ratings stay out of this column.
- Rating / selection basis
- The model and conditions behind the kW figure, or the key fluid properties for fluid suppliers.
- Fluid
- Named dielectric fluid, fluid family or approved fluid list.
- Hardware evidence
- Named server, GPU layout, form factor or validation platform.
- Deployment / documentation
- A named deployment, joint validation or technical document.
