HC-FG is a Potassium Formate/Water solution engineered to perform at low temperatures (-50°C to +218°C). The HC series of fluids have always been non-toxic, non-hazardous, non-flammable heat transfer fluids used in various heat transfer processes around the world, often in food plants. However, in keeping with our ever-changing customer needs, we are proud to now offer this extraordinary fluid with an NSF HT-1 rating (HC-FG) for incidental food contact. Now food/beverage plant managers around the world can count on using this excellent fluid with confidence in their plants for all their cooling/heating needs. Below you will find HC-FG in the same five concentrations as our HC, and we have maintained the same thermal properties for each concentration.
