Nextherm FG

NEXTHERM FG is a high-performance heat transfer fluid that meets H1 requirements and complies with FDA 21 CFR 178.3570 requirements (incidental food contact). NEXTHERM FG utilizes ultra-pure, crystal-clear base fluids that are free from impurities and aromatic compounds that are common in many competitive formulations. The advanced food-grade formulation offers exceptional fluid life with incredibly low carbon and varnish potentia and is rated for a maximum bulk fluid temperature of 320°C.
