Novel lubricant for high temperature heat pump applications on its way

Fuchs Schmierstoffe is developing, within the DryFiciency project, a unique synthetic lubricant for high-temperature heat pumps. This lubricant is chemically stable when combined with OpteonMZ, which is a novel, non-flammable and non-toxic new refrigerant from Chemours, that is not subject to the F-gas regulation. The lubricant is being used for two compressor technologies in DryFiciency project – an adapted screw compressor by Bitzer and a new piston compressor technology by Viking Heat Engines.  

Compressors from Viking Heat Engines and Bitzer – specially engineered to reach up to 160 °C – have been delivered to an experienced Austrian heat pump manufacturer and work is underway to build the first industrial, high-temperature heat pump systems to be installed at DryFiciency’s demo partner sites.
