Material Notes:

Description: Paratherm OR® is a sludge-resistant heat transfer fluid that combines substantial oxidation resistance with excellent thermal efficiency, high flash and fire points and extended service life. This zero-pressure fluid provides precise, uniform temperature control to 550°F in closed-loop thermal oil systems where the heat transfer fluid is more than occasionally exposed to air. The crystal-clear OR fluid is comprised of a unique high-stability base plus high-performance oxidation inhibitor/stabilizer.Information provided by Paratherm Corporation.
