Therminol 54 Temperature Range

Performance Benefits

  • Excellent pumpability – Therminol 54 supports operations with temperatures lower than possible with many other mineral oils.
  • Non-sludge-producing chemistry – The use of Therminol 54 enables life cycle operational cost efficiencies, including optimal pump seal life, fewer system cleanings between refills, and superior fluid life.
  • Excellent resistance to fouling – Because Therminol 54 is a synthetic fluid, it resists the effects of oxidation 10 times better than mineral oils.
