For years Emerson’s semi-hermetic compressors have been the efficiency choice in refrigeration. Discus® compressors have led the industry in terms of energy efficiency for decades, delivering up to 10% more efficiency than any reed reciprocating compressor technology offered by other manufacturers. The performance of those reed reciprocating compressors meets basic market requirements but cannot compete with either Discus® compressors or the new Stream series in terms of low energy consumption.
