Duratherm 600

Rated to 316°C (600°F) and specifically engineered to withstand the extreme oxidation environment of open (to atmosphere) systems, the Duratherm 600 thermal fluid incorporates a proprietary dual-stage anti-oxidant for long, trouble free operation in a variety of applications. It’s an environmentally friendly, non-toxic thermal fluid (heat transfer fluid) capable of providing precise temperature control.

  • 316°C (600°F) maximum operating temperature
  • A tough thermal fluid made for a variety of applications
  • Engineered for use in heat transfer applications with exposure to air
  • Superior protection against sludge and carbon formation
