Refrigeration Compressors

The second generation Copeland Scroll variable speed ZPV2 compressor features intermediate discharge valves to boost efficiency, optimized scroll elements for variable speed performance, positive displacement oil pump for enhanced reliability in low speed operation and brushless permanent magnet (BPM) motor technology for maximum efficiency.
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.
