Central Cooling Systems and Compressor Racks
A central cooling system, or rack compressor system, consists of several compressors for graduated adaptation to your capacity requirement. The compressors work in parallel on a common refrigeration circuit, so a single outdoor unit can control and cool several coolers. The system is mostly used for cold storage plants with more than three rooms, and is preferred in supermarkets and production facilities.
According to your requirements, we supply rack units with a wide selection of optional components, electrically pre-wired or with a switch cabinet, together with a control system adapted to each application.
