Refrigeration systems incorporate Copeland Scroll compressors. Features of the refrigeration systems include increased reliability and extended equipment life due to fewer moving parts; up to 20 percent energy savings and consistent long-term operation over reciprocating compressors; effective management of slug flow without damage to the compressor; and quieter operation. Optionally, the systems can include the Enviro-Control, which is designed to increase reliability, connectivity and food safety while reducing operating costs.
