The designing process begins with gathering of precise data related to user’s needs, taking account of particular industry regulations. With such a basis, we prepare comprehensive design of a refrigeration system which describes the demand for electrical power and cooling capacity. Then, we create the list of electrical materials and installation elements (copper pipes, fixings, wiring, fittings, etc.) and also the list of devices (cooling units, coolers, electrical cabinets, compressor units and condensers).
