JY Ganzhou: match the process gas to the machine arrangement
Jiangxi Gas Compressor's predecessor factory dates to 1951. The company records restructuring in 2000 and completion of its industrial-park relocation and first-phase technical renovation in 2010. The works are in Ganzhou's Zhanggong development area, Shahe industrial park.
The official profile describes foundry, machining, pressure-vessel and final-assembly departments, plus a compressor research institute. The wider catalog includes reciprocating process machines, air compressors, vessels and casting.
M, H, D, L, P and Z arrangements serve different gas duties. Hydrogen may use lubricated, reduced-oil or oil-free variants; the selected oxygen table specifically concerns non-lubricated oxygen machines.

Hydrogen · actual D-family model rows
Compare inlet duty and stage count before choosing a hydrogen compressor
The hydrogen page covers raw, circulating, mixed, tail, regenerated and reducing hydrogen services. It describes lubricated, reduced-oil and oil-free choices, stainless-steel coolers and gas-specific electrical protection.
The manufacturer refers to API 618 and describes flameproof, increased-safety or pressurized motor options. Define the actual gas/area classification, offered protection documents, materials and lubrication; these are not one universal configuration.
The rows below demonstrate why inlet state belongs on the enquiry. Each model has its own flow, discharge, stage count and motor.
| Model | Flow / inlet → outlet | Arrangement | Motor |
|---|---|---|---|
| DW-5/0.8–120 | 5 m³/min 0.08 → 12 MPa | 2 rows · 4 stages | 132 kW · 380 V |
| DW-10/24–36 | 10 m³/min 2.40 → 3.60 MPa | 2 rows · 1 stage | 355 kW · supply to select |
| DW-22/0.04–16 | 22 m³/min 0.04 → 1.60 MPa | 2 rows · 3 stages | 280 kW · supply to select |
Installation size, main-machine mass and supply choices
- DW-5/0.8–120: 5,000 × 4,000 × 2,200 mm · 6.50 t.
- DW-10/24–36: 4,900 × 3,300 × 2,500 mm · 10.00 t.
- DW-22/0.04–16: 5,000 × 1,450 × 2,400 mm · 7.00 t.
The latter two supply cells list 380 V / 6 kV / 10 kV alternatives. Select the actual motor supply and starting arrangement on the offer. Main-machine size and mass do not establish every auxiliary, pipe or shipping component.
Define hydrogen concentration/impurities, gas-side materials, sealing/leakage and vent scope, cooling, controls and qualified commissioning responsibilities with the actual duty.
Hydrogen model facts and project inputs →Oxygen · selected non-lubricated M-family rows
Keep oxygen selections separate from the air and nitrogen tables
The combined catalog image has separate air, oxygen, nitrogen and filling sections. These M-family rows come from the non-lubricated oxygen section.
The manufacturer describes gas-contact stainless-steel housings and stainless-steel cooler cores. For the actual offer, define materials, oxygen cleanliness/preservation, source-pressure range and qualified installation.
4MW-135/1.7–8 explicitly lists 0.17 MPa inlet. The selected /30 rows do not independently state inlet pressure; request it rather than guessing from their names.
All three list 6,800 × 4,000 × 3,200 mm main-machine dimensions and 6 kV / 10 kV supply alternatives. Confirm the actual supply, foundation loads, maintenance clearances and total package dimensions. Source flow is m³/min, not automatically normal volume.
Oxygen model facts and acceptance requirements →Review the purchase in the order the project will be built
The published service program distinguishes design documents, foundation work, installation guidance, commissioning and training. Confirm current applicability, destination coverage and contract terms.
Before foundation construction
Request current load, arrangement, lifting and maintenance-access drawings. The policy identifies D/M machines with at least 12 T piston force for specific foundation/site support; this is not the same as machine mass.
During manufacturing
The company describes assembly/maintenance training for one or two buyer personnel, typically 3–10 days during manufacturing, under its published arrangements. Agree attendance, travel and accommodation, practical scope and test witness points.
During installation and commissioning
Define the installation contractor and manufacturer guidance, utility readiness, gas-side cleanliness/leakage checks, controls/interlocks and acceptance tests. The published large D/M installation-guidance program describes 2–5 working days; actual destination scope belongs in the contract.
After handover
Obtain current manuals, wear-parts lists, inspection schedule and warranty terms. The published policy describes one year from installation/operation or 18 months from arrival, excluding wear parts; clarify the controlling trigger and applicable exclusions in the order.
Prepare a JY gas-duty enquiry
Attach the gas analysis and operating-duty sheet, identify hydrogen or oxygen, and include site utilities and project acceptance requirements.
Prepare the JY process-compressor enquiry →Questions before ordering a JY process compressor
Are all JY hydrogen compressors oil-free?
No. The official hydrogen page describes lubricated, reduced-oil and oil-free variants. Define the selected gas-side design and allowable contamination.
Can the oxygen and nitrogen rows be combined into one performance table?
No. The original catalog image contains separate gas sections. Use the actual oxygen row and obtain its inlet state and reference conditions.
Does 12 T piston force mean a machine weighing 12 tonnes?
No. The published service threshold concerns piston force. The model tables separately list main-machine mass; foundation design needs the actual load drawings.
Do historical export photographs guarantee present availability?
They show manufacturer-reported 2021 project types. Confirm the offered model, manufacturing schedule, tests and destination support for the current order.
