Following an extensive qualification program, compressor specialist BITZER has announced approval of the R1234yf and R1234ze(E) HFO refrigerants for its CSH and CSW screw compressors. The two alternatives to R134a have a global warming potential (GWP) of under ten, while the GWP of R134a is around 1,400. With a GWP of about 600 each, the HFO/HFC blends R513A and R450A are also approved for the CSH and CSW series. Unlike the pure HFO refrigerants, they’re nonflammable.
