• Dielectric heat transfer fluid dedicated to 1-phase immersion and direct cooling systems
  • Colorless, clear liquid with >99.5% purity
  • Non-flammable with no flash point, and non-toxic
  • High boiling point (170°C/338°F) supporting a wide operating range of -100°C to 160°C
  • Low pour point (-100°C/-148°F) and low kinematic viscosity (1.81 cSt @20°C) to minimize pump strain
  • High dielectric strength (>40 kV) and resistivity (1.00E+13 Ohm-cm), allowing equipment to run under power while fully submerged
  • Excellent thermal conductivity (0.111 W/m-K) and low surface tension (17 dynes/cm²) for optimized heat transfer
  • Thermally and chemically stable, with zero ozone depletion potential (ODP)
  • Recyclable through the ECOPROGRAM service for cost-efficient reuse
  • Suitable for single-phase immersion cooling, cold plate/tube direct cooling, dielectric testing, and specialized manufacturing cooling applications
