Product Description

Therminol 75 synthetic heat transfer fluid is a ultra-high temperature liquid phase heat transfer fluid having excellent thermal stability.

Performance Benefits

  • High-Temperature Stability and Performance—Therminol 75 is an exceptionally stable heat transfer fluid. It delivers a heat transfer coefficient which is equivalent or higher than other natural or synthetic liquids in the same boiling range.
  • Low Pressure—Therminol 75 is designed for typical liquid-phase heat transfer fluid systems which operate at low pressures.
  • Critical System Design— Due to the high melting range 40°-70°C (104°-158°F) of Therminol 75, proper system design is important for reliable operation.
