Duratherm XLT-50

Engineered for extended operation in heat transfer applications requiring precise temperature control ranging from -45°C (-50°F) up to 122°C (250°F). The Duratherm XLT-50 heat transfer oil has a wide operating range that makes it well suited for heating and cooling applications in the food processing, pharmaceutical and chemical industries etc.

122°C (250°F) maximum operating temperature
Capable of efficiently cooling down to -45°C (-50°F)
Remains stable across a wide temperature range
Unlike glycols, no special oil monitoring is needed
Provides trouble free operation at any temperature
Safer, low odour alternative than the competition
