Heat transfer oil. Heat transfer/circulation oil for use in closed and open heat transfer systems. Mineral oil that is resistant to thermal cracking and chemical oxidation, which means that the flash point will not change significantly. Good heat transfer capability and viscosity that makes it free-flowing both at start-up and during the operating phase. Thermally stable oil with a long lifespan.

Viscosity at 40°C 30.4 Cst, at 100°C 5.4 Cst, Pour point -6°C, Flash point 230°C, Specific gravity at 15°C 0.857, Micro - Conradson Residue, wt% D 4530, 0.05 (max).
