Description
DURATHERM G
Duratherm G is a glycol based thermal fluid rated to 260°C (500°F), a proprietary additive system that not only helps the fluid last longer and run cleaner, it makes it the ideal choice for extreme oxidation environments including demanding, open bath applications.
- 260°C (500°F) maximum operating temperature
- High flash point of 249°C (480°F)
- Ideal for use in extreme oxidation environments like open baths
- Polyalkylene glycol based thermal fluid with enhanced performance
