Wuleng · Wuhan New World Refrigeration Industrial
A Wuhan screw-equipment manufacturer working across cold and heat
武汉新世界制冷工业有限公司, known as Wuleng, traces its history to Wuhan Freezer Works, established in 1954. The company reports moving to the Jinyintan development area in Wuhan's Dongxihu district in February 2008.
The company introduction describes a 250,000 m² site with precision machining, compressor/unit assembly, pressure-vessel production and four performance-test stations. Its reported capacity of more than 3,000 screw products a year describes manufacturing capability; agree current lead time for the selected order.
Bingshan's 2026 interim filing identifies Wuhan New World as a wholly owned subsidiary and records its absorption of Wuhan Lanning Energy Technology. Keep this Wuhan entity distinct from the group's Dalian manufacturers.
Identify what the process needs the compressor to do
Remove a specified process heat load
S-series swept volume is a compressor geometry/rating reference. Select cooling output at the refrigerant's actual evaporating and condensing duty.
Set the refrigeration conditions →Deliver the actual gas to a receiving pressure
The gas-skid envelope needs composition, suction conditions and flow reference definitions before model selection.
Define the gas stream →Raise secondary steam to useful heating duty
A vapour compressor consumes input to raise pressure and temperature. A screw expander instead uses a pressure drop to generate output.
Build the vapour balance →S-series · Large-displacement screw refrigeration
Theoretical displacement is not refrigeration capacity
The family lists 3,512–9,059 m³/h theoretical displacement. This is not cooling kW or free-air delivery. Refrigerant and the cycle conditions determine the refrigeration duty.
| Evaporating temperature | −45°C to +5°C |
|---|---|
| Condensing temperature | No greater than 40°C |
| Discharge temperature | No greater than 105°C |
| Cooling-water inlet | 20–32°C |
| Oil temperature | L-DRA/B oils ≤65°C WL oils ≤70°C |
Confirm these conditions for the chosen model, refrigerant and oil. Evaporation above +5°C needs separate selection review; no cooling capacity or motor kW is inferred from the swept-volume range.
From process load to a selected machine
Send process/secondary-fluid load and temperatures, refrigerant choice, superheat/subcooling and economiser requirements. Request a model-specific refrigeration table with power at that duty.
The page describes automatic slide-valve and internal-volume-ratio adjustment, differential-pressure oil supply with prelubrication, mechanical sealing and rolling bearings. Agree the offered controls, oil cooling/separation and protective functions rather than assuming every package is identical.
Single- / two-stage natural-gas compression
Select a paired gas duty, then define the skid interfaces
| Volumetric flow | 227–12,000 m³/h |
|---|---|
| Inlet pressure | 0.05–2.0 MPa |
| Outlet pressure | 2.0–4.2 MPa |
| Motor power | 55–2,000 kW |
| Flow regulation | 10–100% stepless, family description |
| Optional volume ratio | 2.5–5.0 stepless adjustment |
The source does not state the volumetric reference conditions or gauge/absolute pressure basis. Ask for those definitions; m³/h is not silently relabelled Nm³/h. Each quoted model must satisfy a specific paired duty.
Gas and suction
Composition, moisture/liquid content, corrosive constituents, inlet temperature and minimum/normal/maximum suction conditions. Define the flow basis and receiving-pipeline pressure.
Delivered skid
Separation, interstage/discharge cooling, drains, materials, instrumentation/shutdowns and applicable area classification. Agree the selected machine's performance and total package input.
Installation
Modular arrangement, transport envelope, piping/electrical interfaces and utilities. Request gas-tightness/performance test conditions, startup procedures and commissioning responsibilities.
Water-vapour screw recompression
Turn secondary vapour into a defined heating stream
The described package uses a twin-screw water-vapour compressor, steam piping/valves, a spray-water cooling system and a lubrication train with oil tank, cooler, filter and pump.
- Published inlet boundary
- Above 0.1 MPa
- Published outlet boundary
- Up to 2.0 MPa
Gauge/absolute basis is not printed. No steam mass-flow or motor rating is supplied on the source page. Establish the actual model through the proposed heat and mass balance.
Available vapour
Mass flow, pressure, temperature, wetness and composition; normal/minimum load and startup conditions.
Compression & conditioning
Required discharge state, spray-water quality/flow, separation/drainage, lubricant isolation and protective functions.
Useful process heat
Heating-stream requirement and acceptance interface. Compare useful recovered heat and purchased electricity over the same process boundary.
Food, chemical, paper, salt and pharmaceutical applications are named by the manufacturer. A listed application alone does not establish hygienic or contamination-free suitability for every process; specify the required steam quality and the acceptance method.
Water-vapour recompression and process-balance requirements →Agree manufacturing, system and commissioning responsibilities
- Machine selection: exact model, medium, paired operating point, power and full operating envelope.
- Package boundary: equipment/instruments, lubrication/treatment, vessels, utility duty, drawings and maintenance/lifting space.
- Project interfaces: site piping/electrical work, process integration, control signals, transport/assembly and commissioning owner.
- Acceptance: agreed test conditions, witnessing, required model/vessel/destination documents, process quality and parts/service scope.
Company history and group ownership provide context. Obtain the actual offered equipment's performance reports and required project documents separately.
Prepare a Wuleng process enquiryClarify the quantities before comparing offers
Is 3,512–9,059 m³/h the refrigeration capacity?
It is the S-series theoretical displacement range. Cooling capacity requires the selected refrigerant and actual evaporating/condensing duty, with the cycle and package conditions stated.
Are the gas values normal cubic metres and gauge pressures?
The original page says m³/h and MPa without those definitions. Ask for volumetric reference conditions and absolute/gauge pressure basis in the selected offer; they are not interchangeable labels.
Does the steam compressor produce electricity like a screw expander?
A compressor uses input to raise vapour pressure and temperature for reuse as heat. An expander uses a pressure drop to produce mechanical output. Compare the actual process and energy balance for the intended equipment.
Can the steam outlet limit define the complete package?
It is one family boundary. Steam mass flow, suction/discharge states, composition, spray-water and lubricant/process interfaces still need a selected model, heat balance and acceptance specification.
