Two-phase immersion cooling companies
Two-phase immersion removes heat by boiling a dielectric fluid at the chip and condensing it above the bath. These companies sell two-phase tanks, servers and fluids, from Delta’s 100 kW tank to Sugon’s 900 kW-class cabinet.

What needs checking before buying a two-phase system?
Ask for the named fluid, its boiling point, the vapor containment design, the condenser rating and the service process. Chemours’ Opteon 2P50 boils at 48.9°C and ships as a developmental fluid through pilot programs, including LiquidStack’s DataTank 4U test kit.
