Cooling Circuit

Supplying a stable installation against low operational costs are in first instant a contradiction. The numbers of capacity steps, the number of compressors, the choice of the refrigerant and the cooling medium are the key factors to wipe out this contradiction. Using natural  refrigerant as ammonia (NH3) and carbon dioxide (CO2) make a social contribution. One of the options is the selection of the semi-hermetical cylinder or screw compressors, in which the cooling capacity is determined by the desired suction pressure and the desired temperature. The result is, a low energy consumption, a high C.O.P. of the compressors and a stable system.
