Product overview
Vocke V11 single-stage semi-hermetic screw refrigeration series from Zhejiang Vocke Refrigeration (Jinhua)
Vocke classifies V11 as a single-stage screw refrigeration series. Its English product range identifies the screw compressors as semi-hermetic. The original V11–V14 series image is a family illustration; specify the full V11 model and current drawing for an order.
The catalogue pairs V11K84-30 with displacement of 84/101 m³/h at 50/60 Hz, maximum current 52 A, maximum power 33 kW and weight 170 kg. V11N84-20 shares the displacement entry but has 48 A maximum current, 29 kW maximum power and 166 kg weight. The notation chart identifies K as single-stage high-temperature and N as single-stage low-temperature. Keep these model-dependent ratings separate; maximum electrical power is not cooling output or electrical consumption at every duty point.
The shared electrical entry is three-phase 380–420 V at 50 Hz or 440–480 V at 60 Hz, with a delta/double-delta notation. Confirm the exact motor winding, terminal diagram, starting arrangement and allowable supply with the offered model. The V11 connection record lists 42 mm discharge and 54 mm suction. Request the current drawing, service-valve arrangement, mounting and piping interfaces.
The series describes motor protection, PTC discharge-temperature protection, an internal discharge check valve and provision for an external economizer. Economizer connection provision is not an included complete economizer package. Specify separator/oil management, injection arrangements, capacity control, protection module and auxiliaries with the compressor quotation.
For selection, provide refrigerant, required refrigeration load, evaporating/condensing temperatures, suction superheat, liquid subcooling and frequency. Obtain the exact cooling capacity and input at that point, the operating envelope and any economizer assumptions. Displacement in m³/h cannot replace a refrigeration-capacity selection in kW. Confirm refrigerant, oil and destination requirements together with installation, commissioning and replacement-part responsibilities.

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. |
