• Dielectric heat transfer fluid engineered for 1-phase and 2-phase immersion and direct cooling systems
  • Colorless, clear liquid with >99.5% purity
  • Non-flammable with no flash point, and non-toxic with no EUH-phrase hazard classifications
  • Extremely low pour point (-135°C/-211°F) and low kinematic viscosity (0.38 cSt @20°C) for efficient pumping
  • High dielectric strength (28 kV) and resistivity (1.00E+09 Ohm-cm), allowing equipment to run under power while fully submerged
  • Excellent thermal conductivity (0.069 W/m-K) for superior heat transfer and uniform cooling
  • Thermally and chemically stable for extended service life, reducing total cost of ownership
  • Medium-low Global Warming Potential (GWP) and zero ozone depletion potential (ODP), with recyclability through the ECOPROGRAM service
  • Suitable for dielectric testing, cold plate/tube direct cooling, and specialized manufacturing cooling applications
