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
