Dynalene HC

Potassium Formate Heat Transfer Fluid (-58°F to 425°F)

NSF Logo
Dynalene HC now available in food safe formula

Now all your favorite Dynalene HC concentrations are available in a food safe formula.

Dynalene HC/Potassium Formate is a water-based, low-temperature heat transfer fluid engineered to deliver excellent heat transfer performance in applications down to -58°F (-50°C). With a temperature range from -50°C to +218°C, Dynalene HC easily exceeds the performance of other water-based chemistries such as glycol/water mixtures and calcium chloride solutions, as well as hydrocarbon- and silicone-based fluids. This fluid comes in five concentrations and is non-toxic, non-hazardous and non-flammable. Custom formulations are available upon request.

Dynalene also offers a product line of filtration systems that helps in removing debris, rust, and other particulates from HC fluids. Particulates may form over time due to corrosion or contamination of the fluid. These particles may form deposits that can contribute to additional corrosion, loss of heat transfer capacity, and obstruction of passages in the system. Installing an in-line or slip-stream filter in the system will help prevent these deposits from building up and creating operating problems. Dynalene’s filtration systems have been specifically tested to confirm compatibility with our HC product line. Click here to view our filtration product listing.

Dynalene HC/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’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 heat transfer fluid, which in turn makes Dynalene HC a more thermally efficient solution.
