Reciprocating compressor-receiver unit
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.
- Refrigeration capacity: 3.0-74 kW.
- Condenser type: air, plate, shell and tube.
Standard equipment of the unit:
- Polus-Sar semi-hermetic compressor equipped with shut-off valves, crankcase heater, INT69TM electronic motor protection modules, oil pump, and electronic lubrication relays (DELTA-P).
- The discharge line consists of a vibration damper and a discharge pipe.
- The suction line consists of a suction pipe, a vibration damper, and a mechanical filter.
- Liquid pipeline: receiver, liquid pipe from the condenser to the receiver with a check valve, liquid pipe to the evaporator with a filter drier, and sight glass.
- The control and safety system consists of a high and low-pressure switch.
Unit frame. - Dust and moisture-proof control box for the unit and condenser.
- Documentation: certificate, operation manual, hydraulic and electrical wiring diagrams.
Optional Features
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.
