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.
