Applications

• High-pressure cylinder filling: industrial and natural gas cylinders and other high-pressure filling applications;

• Natural gas / nitrogen boosting: boosting, transportation and storage of natural gas and nitrogen;

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

• Gas boosting & transportation: boosts low-pressure gas sources for transportation and central gas supply;

• Multi-media boosting: supports air, nitrogen, natural gas and other media for a wide range of applications.

Product Features

• High-pressure output: boosts low-pressure sources to 35 MPa (350 bar) with high pressure and stable performance;

• Compact: small footprint with moving handles for easy transport and on-site layout;

• Two-stage compression: staged boosting with reasonable pressure ratios, high efficiency and smooth operation;

• Low-noise operation: unit noise ≤ 65 dB for quiet running;

• Multi-gas media: supports air, nitrogen, natural gas and other media for a wide range of applications;

• Energy-efficient: boosts existing low-pressure air sources to maximize energy savings and reduce production costs;

• Low vibration 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.
