Immersion Fluid Characteristics for Data Center Cooling

As rack power densities push beyond 100 kW and AI accelerators drive unprecedented thermal loads, immersion cooling is rapidly emerging as a compelling solution for next-generation data centers. But as adoption accelerates, one decision stands above the rest: fluid selection. The coolant is not just a supporting component — it defines the operating environment for every processor, connector, and circuit board in your system.

This white paper, authored by Dr. Dennis Schuetzle, Chief Technology Officer at Infinium, examines the six major immersion fluid categories and explains why the molecular architecture of your coolant determines long-term reliability, dielectric stability, oxidation resistance, and sustainability performance.

Inside the white paper:

• A comparative analysis of mineral oils, PAOs, esters, silicones, fluorocarbons, and Fischer-Tropsch (FT) synthetic hydrocarbons across six performance dimensions
• Why FT fluids deliver superior dielectric stability, thermal conductivity, and oxidation resistance for high-density AI compute
• How fluid chemistry affects hardware longevity, maintenance cycles, and total cost of ownership
• How Infinium Edge fluids are engineered at the molecular level for the demands of next-generation immersion cooling
