Food Grade Heat Transfer Fluid USDA, H-1 Synthetic, HTF FG-32

Food Grade Heat Transfer Fluid

Food Grade Heat Transfer Fluids are made with the finest thermally and oxidatively stable base fluids. They are further enhanced with proprietary additives that greatly extend their life over normal synthetic fluids and provide for even higher operating temperatures in both open and closed systems. They are approved by the USDA for H-1 applications (lubricants with incidental food contact). They fully comply with the requirements of FDA 178.3570. Series Heat Transfer Fluids are NON-Toxic and NON-Hazardous and do not form carbon in most applications.
