BOCK HC compressor HG56e HC

BOCK semi-hermetic hydrocarbon compressors (HC)

for refrigrants R290 (Propane) and R1270 (Propene)

BOCK compressors for hydrocarbons meet all the requirements of the F-Gas Regulation and can be used on a long-term basis. This means planning security for plant manufacturers, users and investors.

For the use of R290 / R1270, Bock has developed a separate compressor variant for hydrocarbons. The HG HC range evolved from the powerful semi-hermetic HG compressor sereis and was holistically optimised to meet the special requirements of flammable refrigerants.
