Duratherm LT

Engineered for a variety of heat transfer fluid processes requiring 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 (-20°F) – eliminating the need for heat tracing often required in outdoor applications.

225°C (437°F) maximum operating temperature with excellent cooling properties
Pumpable at temperatures down to -29°C (-20°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
