Wuleng S-series screw refrigeration compressors — Wuhan New World Refrigeration (Bingshan group)

Datasheet

Product overview

Power: Select refrigerant and duty · Pressure: Refrigeration-duty selection · Flow: 3512–9059 m³/h theoretical displacement

Wuleng's S series covers large-displacement screw refrigeration compressors. Its official product page lists theoretical displacement of 3,512–9,059 m³/h across the family. This is swept volume, not refrigeration kW and not free-air delivery. Select the refrigerant and actual evaporating/condensing duty before comparing cooling output or input power.

The published family conditions are evaporation −45°C to +5°C, condensation no greater than 40°C, discharge temperature no greater than 105°C and cooling-water inlet temperature 20–32°C. Oil temperature is limited separately to 65°C for L-DRA/B refrigerating oils or 70°C for the WL oil series. These boundaries belong to the manufacturer's S-series description; ask for their applicability to the selected model, refrigerant and oil. Evaporation above +5°C calls for a separate selection rather than extending the range.

The page describes fourth-generation WL-C rotor profiles, rolling-bearing support, mechanical seals, differential-pressure oil supply with prelubrication, automatic capacity-slide adjustment and adjustable internal volume ratio. Ask how the quoted package implements those arrangements and supplies oil cooling/separation, controls and protective functions at the intended duty.

Provide process or secondary-fluid load and temperatures, refrigerant preference, superheat/subcooling and economiser needs, available cooling water and electrical supply. Request a model-specific refrigeration performance table, drawings and maintenance/lifting access, acceptance-test conditions, required vessel/destination documents and commissioning scope. The original manufacturer image illustrates the S-series package; the family range does not determine a final unit's motor power or dimensions.
