"Using a horsepower range for the compressor doesn't tell you what you want to know," said Jim Mozer, marketing director for Copeland Refrigeration, part of Emerson Climate Technologies, announcing the change for the company's Discus® line of refrigeration compressors. "A new nomenclature allows us to put the compressor's capacity and application in the name, so it will make the model easier to spec and give designers more options."
Discus (disk valve) semi-hermetic reciprocating compressors make up the predominant technology used in supermarket refrigeration in the United States, Emerson officials said.
