Therminol 58 Heat Transfer Fluid

Product description

Therminol 58 is an efficient, reliable, medium-temperature synthetic fluid engineered to deliver exceptional heat transfer performance at maximum bulk temperatures up to 300°C (575°F). It delivers dependable, uniform process heat with no need for high pressures. With a superior life span, Therminol 58 provides excellent performance over the fluid life when compared to common mineral oil-based fluids as well as lower-tier synthetic heat transfer fluids.

Performance Benefits

  • Optimal pumpability—Non-sludge-producing chemistry enables pumpability at lower temperatures than the majority of other mineral oil-based heat transfer fluids.
  • Excellent compatibility—Therminol 58 is noncorrosive to metals commonly used in the construction of heat transfer systems.
  • Excellent resistance to fouling—Therminol 58 has been shown to be significantly less sensitive than mineral oils to the negative consequences (sludging, fouling) of thermal oxidation.
