Semi-Hermetic

Semi-hermeticBanner_EN

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 either with Discus compressors nor with the new Stream series in terms of low energy consumption.&nbsp
