The Plug n’ Cool (EPC) sealed-unit line is a cooling solution for commercial refrigeration compressor replacements or retrofits. EPC units use R-290 refrigerant and are designed for grocery store and supermarket use. Plug n’ Cool is a sealed unit, shipped fully charged with R-290, around which OEM design engineers can build market-ready, water-cooled display systems. The fully charged units eliminate the need to install R-290 charging equipment. Retailers need only water supply and return lines to the cabinet.
