The Discus range provides the best performance of all semi-hermetic compressors available on the market. It is mainly used in medium and low temperature refrigeration applications requiring energy consumption to be kept to a minimum. The specificity of the Discus is a patented Delta Reed valve plate design that reduces re-expansion volume to a minimum. It gives better energy efficiency and cooling capacity than traditional semi-hermetic compressor designed with Reed valve plate technology. The Discus range offers 2, 3, 4, 6 and 8 cylinder compressors from 4 to 60hp and is approved for R22, R134a, R404A and R407C refrigerants.
