Immersion suppliers differ in tank mechanics, coolant strategy, server ecosystem, heat rejection, geographic support, and whether they act as an equipment vendor or a full data-center integrator.
Scaled specialist platforms
Submer and GRC have visible commercial product lines and public deployment references. LiquidStack retains immersion technology alongside its expanding direct-to-chip distribution business.
Focused and regional specialists
Asperitas, DCX Liquid Cooling, and Midas Immersion Cooling add European and U.S. alternatives with distinct tank and integration approaches.
What to verify
Ask for approved hardware lists, fluid warranty, long-duration materials testing, service workflows, reference contacts, and measured facility-boundary energy—not only tank heat capacity.
