Datasheet
Product overview
Power: Selected compressor input required · Pressure: Refrigerant operating envelope required · Flow: Refrigeration duty; not air FAD
The Suzhou factory profile explicitly includes semi-hermetic single-screw refrigeration compressors, medium/low-temperature variants and heat-pump/heat-recovery designs. This existing HS URL is retained as a selection reference. The current source confirms that construction family, not an exact HS model catalogue or universal refrigerant/temperature envelope.
Select using refrigerant, evaporation and condensing conditions, superheat/subcooling basis, required cooling duty and modulation range. Obtain the actual compressor code and map, absorbed electrical input, supply and starting/control arrangements. Cooling duty in kW is not motor kW, swept volume is not air FAD, and different refrigeration applications require different operating envelopes.
The separate official PFS complete-chiller example lists 488–2241 kW cooling duty with R134a/R410A alternatives and slide-valve regulation. Those are system-family facts, not numerical ratings of every semi-hermetic compressor or proof that both refrigerants work in one offered unit.
For replacement, provide chiller/compressor nameplate and serial, refrigerant/oil, operating/fault history, electrical protection, control connections and piping/access dimensions. For an OEM package, freeze refrigerant circuit, lubrication, motor cooling, regulation and protective limits. Agree the exact performance/rating basis, conformity documents, installation, commissioning, genuine spares and warranty. No substitute complete-chiller photograph is presented as a bare HS compressor.

Specifying a Refrigeration duty
| Duty | Write on the RFQ |
|---|---|
| Refrigeration screw compressor manufacturers in China | A refrigeration screw compressor is selected for a refrigerant and operating conditions. Start with required cooling capacity, evaporating and condensing temperatures, electrical supply and the system arrangement. An air-compressor pressure rating or a motor nameplate alone cannot define this duty. |
