UNIGY: gas-compression manufacture in Luoyang, sales headquarters in Nanjing
优尼捷（洛阳）工业设备有限公司 describes its Luoyang factory as established in 2014, with production in Hongshan industrial park and sales headquarters in Nanjing.
The company markets dry oil-free gas compressors, PET/high-pressure air equipment and nitrogen boosters, alongside a separate UNI screw-air range and vacuum-related service/parts business.
Its account says the UNIGY brand originated in Singapore. This is company-reported brand history; it does not establish a Singapore factory or ownership of the Luoyang entity.
Select by the actual process
Three existing product paths, three different duty sheets
Bottle-line air
PET reciprocating air and boosting packages
The OF900/40 and PET1-3600 pages describe a base/drive, interstage and aftercooling, check and safety valves, gauges, pressure switching, drains and motor starter. Confirm the actual staged configuration and drive on the offer.
The headline range is 0.7–5.0 MPa and 0.1–20 m³/min. It is not a paired model-duty table. Mixed PET1 lower-page text names another model and a different flow envelope; do not combine those into one machine rating.
- Provide bottle-line count, blow pressure and cycle/peak demand.
- Define upstream pressure/temperature and available flow for boosting.
- Agree air treatment, receiver and purity acceptance at the point of use.
Process-gas boosting
Nitrogen: start with the available inlet
The specific OF20-150-8-DP page gives 20 m³/h, 8–10 bar inlet and 20–160 bar discharge. The outlet interval is a selection envelope, not proof of identical capacity and power at every pressure.
Provide nitrogen purity/impurities, inlet minimum/normal/maximum conditions and target discharge. A separate WB17 listing has conflicting ranges and incomplete flow units, so it is excluded from numerical comparison.

Industrial air room
UNI twin-screw air: match the demand profile
The UNI2-400VSD page lists 2–400 kW, 0.5–70 m³/min and 0.7–1.3 MPa as family limits. They are not paired operating points. Later copy also names UNI2-250KWVSD; request a current exact-model datasheet.
The described range uses a twin-screw airend and variable-frequency control. Confirm lubrication, electrical supply, usable control range and measured package input over the actual peak/low-load demand.
Keep receiver, dryer, filtration, condensate and commissioning scope explicit. Oil-free/Class 0 claims from a different gas-compressor page cannot certify this screw family.

A purity requirement needs actual test evidence
The site claims Class 0 for specified oil-free equipment. Obtain current issuer documentation, certificate number, exact model scope and test conditions for the offered machine.
Oil-free compression does not establish every purity target of a complete air system. Include upstream contamination, treatment, piping and the buyer's accepted measurement point in the specification.
Gas names do not make machines interchangeable
UNIGY's wider process catalog names nitrogen, helium, hydrogen, carbon dioxide and recovery applications. Select gas-side materials, seals, leakage/vent handling, pressure and temperature for the actual medium.
A nitrogen listing or a broad “inert gas” label is not approval to reuse one offered machine for a different process gas.
Vacuum service and parts: distinguish service marketing from authorization
The official site separately lists vacuum-pump repairs and parts for several brands. If that service is needed, identify the actual machine, serial, parts and proposed work. Obtain current written authorization where it is material to the purchase; a branded repair listing alone does not establish a third-party manufacturer's current authorization or warranty coverage.
Define the upstream supply, compressor and downstream process
Upstream · what reaches the inlet?
PET/nitrogen boosting: minimum/normal/maximum pressure and temperature, available flow, gas composition and impurities. UNI air room: site ambient/altitude, electrical supply and ventilation.
Compression · what is the actual offered duty?
Exact model/revision, actual suction and discharge, capacity reference, stages, selected drive and package input, cooling, controls/protections and gas-side material/lubrication requirements.
Downstream · what must the process receive?
Use-point pressure and peak/continuous demand, purity/dew-point/particle targets, receiver and treatment, pipe/hose losses, condensate and leak/vent handling.
Handover · what is included at acceptance?
Manufacturing address and inspection plan, witnessed test conditions/records, applicable vessel documents, lifting/foundation and maintenance drawings, wear parts, commissioning and destination support responsibilities.
Prepare an identifiable UNIGY process enquiry
Name PET air, nitrogen boosting or industrial screw air and include the actual inlet, outlet and demand conditions.
Prepare the UNIGY duty enquiry →Questions before an UNIGY quotation
Does the nitrogen booster generate nitrogen?
The OF20 entry compresses supplied nitrogen and specifies an 8–10 bar inlet. Define the upstream nitrogen supply and purity separately; the compressor listing does not describe a complete generation plant.
Can the PET model name establish an exact flow and pressure?
No. The pages provide broad ranges and contain mixed-model text. Request the actual paired duty, inlet/reference conditions, drive and package configuration.
Are all UNIGY screw machines Class 0 oil-free?
The screw-air catalog is a separate path. Confirm actual lubrication and exact-model purity evidence rather than transferring claims from oil-free reciprocating gas products.
Does the Singapore brand-history statement mean the plant is in Singapore?
The official account places production in Luoyang and sales headquarters in Nanjing. Its brand-origin statement does not establish a Singapore manufacturing site.
