Applications

• Oilfield gas injection: gas-drive oil recovery, gas-storage / gas-well injection and other energy extraction fields;

• Gas industry: CNG filling stations, natural gas compression and high-pressure cylinder filling;

• High-pressure filling: industrial high-pressure cylinders, storage-vessel filling and central gas supply;

• Leak & pressure testing: high-pressure air-tightness inspection and pressure-endurance testing of pipelines, vessels, valves and other workpieces;

• Energy equipment: compressed-air energy storage for hydropower stations, offshore exploration, marine and other fields;

• Air supply for large-scale process and energy equipment applications.

• This equipment handles multiple compression media including air, nitrogen, helium, argon and natural gas, meeting the high-pressure gas media requirements of different industries.

Product Features

• High-pressure multi-stage compression: four/five-stage compression structure with staged boosting, reasonable pressure ratios up to 35–40 MPa, high efficiency and smooth operation;

• Large-displacement high pressure: 1–10 m³/min flow rate for large-scale high-pressure central air supply;

• Water-cooling system: independent circulating cooling water (2–20 t/h) with excellent heat dissipation and controlled discharge temperature for long-time continuous large-flow operation;

• Low noise, low vibration, low fuel consumption and high durability for stable, reliable long-time continuous operation;

• Uses high-quality SKF bearings and premium parts for durability and long service life;

• Intelligent control system: complete instrumentation and valve groups with real-time monitoring, simple operation, and comprehensive pressure, temperature and safety protection;

• The factory is ISO 9001 certified and holds a national industrial product production license; products pass multiple machining, inspection and endurance test processes with strict control from component selection to final delivery;

• 1-on-1 professional selection guidance, installation & commissioning training and regular follow-up inspections; multiple service centers nationwide provide fast after-sales support.
