Dynalene HC-FG

Food Safe Potassium Formate Heat Transfer Fluid (-58°F to 425°F) Temperature Range for Closed System: -58°F to 425°F / -50°C to 218°C

Dynalene 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 (Dynalene 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 Dynalene HC-FG in the same five concentrations as our Dynalene HC, and we have maintained the same thermal properties for each concentration.

Dynalene HC-FG/Potassium Formate heat transfer fluid is an excellent alternative to calcium chloride and other brine solutions because it demonstrates a higher thermal efficiency and lower corrosion rate. This fluid, as compared to other glycols, calcium chloride, and other brine solutions, should lower the leak and spillage rate, and reduce maintenance and repair costs on refrigerated systems. This is due to Dynalene HC-FG’s use of “safe” chemistries resulting in a high level of corrosion inhibition. The viscosity of calcium chloride solutions is also noticeably higher than Dynalene HC-FG heat transfer fluid, which in turn makes Dynalene HC-FG a more thermally efficient solution.
