Process Principle

Pressure Swing Adsorption (PSA) nitrogen generators use carbon molecular sieves as the adsorbent. Based on the principle of pressure reduction and desorption, oxygen is adsorbed from air to separate nitrogen automatically.

Product Quality

♦ Excellent material selection, reasonable configuration, high machining accuracy.

♦ Strict process inspection and ex-factory testing.

♦ Stable and reliable long-term operation, extremely low failure rate.

Technical Advantages

♦ Adopts multiple advanced technologies with superior process and excellent performance.
♦ Rich experience in design and manufacturing, strong R&D and innovation capability.
♦ All equipment from high-efficiency oil-water separator to nitrogen buffer tank outlet is independently designed and manufactured by the company, providing greater advantages over peers in equipment design, commissioning, service and spare parts replacement.

Energy Saving & Environmental Protection

Low energy consumption, high efficiency, low noise, and no environmental pollution.

After-sales Service

Convenient and fast maintenance, complete sales and after-sales service system.
