About NuTherm® PF-50
NuTherm® PF-50 is a high-performance potassium formate/water heat-transfer fluid engineered specifically for open-bath systems requiring exceptional low-temperature performance and efficient thermal transfer. Designed for open-bath operation from −51°C to +110°C (−60°F to +230°F), NuTherm® PF-50 combines high thermal conductivity, high specific heat and low viscosity to provide an efficient alternative to conventional glycol, PAG and calcium chloride open-bath heat-transfer fluids.
NuTherm® PF-50 is nonflammable, biodegradable, CFC-free and formulated with a robust corrosion-inhibition package for use with a broad range of compatible metals and polymers. Its low viscosity helps reduce pumping resistance while its favorable thermophysical properties promote efficient temperature control in demanding low-temperature baths, process-cooling equipment, environmental and thermal testing systems, and other open-bath thermal-management applications.
Contact NuGenTec technical experts for assistance evaluating NuTherm® PF-50 for your open-bath heat-transfer, low-temperature process-cooling, testing, or temperature-control system.
