Duratherm LT

Engineered for a variety of applications requiring process heating and cooling, Duratherm LT is ideal for batch processing operations requiring a low temperature heat transfer fluid that is pumpable down to -29°C (-30°F) – eliminating the need for heat tracing often required in outdoor applications.

  • 316°C (600°F) maximum operating temperature with excellent cooling properties
  • Pumpable at temperatures down to -29°C (-30°F)
  • Capable of performing both heating and cooling cycles
  • Suitable for use in outdoor heating and cooling applications
  • Runs cleaner for a longer service life
  • Easy to dispose of along with other waste oils
