* Compressors cooling capacity is given on the basis of one compressor operation for freezing compartments, with temperature maintenance inside them of minus 18 0С.

** One compressor in the unit is a stand-by. One compressor operates for freezing compartments; another compressor operates for high-temperature compartments. The stand-by compressor may operate for any compartment.

*** Power consumption is given on the basis of one compressor's operation for low-temperature mode. In order to provide more detailed calculation of power consumption and quantity of water supplied to the condenser, consult the manufacturer.

The refrigeration unit has frequency regulation of each compressor which permits to maintain temperature in chambers to a high accuracy, save electric power and reduce cooling water consumption.

The refrigeration unit consists of an auxiliary condenser which provides operation of the whole refrigeration unit.

JSC “ZASLON” may supply a refrigeration unit with the refrigeration capacity required by a Customer.
