Thanks to the optimised drive units in the BOCK HC compressor series (types: HG44e HC, EX-HG44e HC, HG56e HC and EX-HG56e HC) for hydrocarbon refrigerants, the operating limits for R290 and R1270 could be significantly extended, offering more efficiency and performance in heat pump applications.
BOCKlub G68 compressor oil plays a major role in this. The used BOCKlub G68 compressor oil with high viscosity index and high thermal stability shows excellent lubrication properties at low and high evaporation and condensing temperatures. As a result, a significant increase in performance and extension of the compressors applications could be achieved.
These advanced compressor engines continue to demonstrate reliability and long service life even at increased operating limits. This allows the compressors to be used in heat recovery applications and provides a new, modern and far more efficient solution for the heat pump sector.
