About NuTherm® HC-50
NuTherm® HC-50 is a high-performance potassium formate/water heat-transfer fluid engineered for closed-loop systems requiring exceptional low-temperature protection and efficient thermal transfer. With a freezing point of −55°C (−67°F), high thermal conductivity, high specific heat, and low viscosity, NuTherm® HC-50 provides an efficient alternative to conventional glycol, PAG, and calcium chloride heat-transfer fluids.
NuTherm® HC-50 is nonflammable, biodegradable, zero-VOC, and formulated with a robust corrosion-inhibition package for use with a broad range of common metals including stainless steel, carbon steel, cast iron, copper and copper alloys, nickel alloys, titanium, and aluminum. Its favorable thermophysical properties help reduce pumping resistance while improving heat-transfer efficiency across demanding refrigeration, process-cooling, and thermal-management applications.
Contact NuGenTec technical experts for assistance evaluating NuTherm® HC-50 for your closed-loop heat-transfer, refrigeration, process-cooling, or low-temperature thermal-management system.
