The Polus-Sar compressor-receiver refrigerating machine is a product (in assembly) consisting of one reciprocating compressor and receiver, mounted on one frame. It is one of the parts of the refrigeration machine. Models have equipment operation modes protection and control devices. Our units are designed and manufactured based on semi-hermetic reciprocating compressors from «Dorin», «BITZER», «Copеland», «Danfoss», «Frescold», «Carrier», «Bock», «Gea», «Maneurop».
Compressor-receiver units are designed for refrigeration of chilled and frozen food storage chambers, as well as for other applications for refrigeration, and are supplied ready for operation. The compressors are HFC/HFO refrigerants compatible. The cooling loop of the unit has been leak-tested and filled with dry nitrogen excessive pressure of 1 - 1.5 bar. The compressor and oil separator are filled with oil. All control board automation components are tested, product defects are eliminated immediately on the spot.
The units use high-quality components from well-known European companies: BITZER, Danfoss, ALCO CONTROLS, BECOOL, Carly, CPS, Eliwel, Mastercool, Ranco, Refco, Swep, Gvn, Bernzomatic, Errecom, Henry. Control boards are assembled with Schneider Electric, Simens, ABB, CAREL, ELIWELL, Danfoss components.
LS - a liquid separator on the suction line.
F - head of compressor cylinder block blowdown fan (depending on the evaporating and condensing temperature).
LIS - liquid injection system (depending on the boiling and condensation point).
OS - the oil separation and return system consists of an oil separator on the discharge line, an oil return line with a shut-off valve, and sight glass.
СС - installation of the CC capacity control cover on the compressors.
W - a set of winter control may include KVR and NRD, condensation pressure switch, condenser fan speed controllers.
