NEXTHERM HF is a heat transfer fluid used in numerous types of heat transfer systems. It is made with thermally and oxidatively stable synthetic base fluids that are further enhanced with proprietary additives. This formulation greatly extends the heat transfer fluid life over normal and other synthetic fluids. NEXTHERM HF provides exceptional performance in very high operating temperatures in both open and closed systems. NEXTHERM HF has a very high flash point and is rated non-toxic and non-hazardous.
