Fully Automatic PSA Nitrogen Generator 5-5000 Nm3/h 95-99.9995% Purity

The PSA nitrogen generator utilizes carbon molecular sieve (CMS) as an adsorbent, operating on the pressure swing adsorption principle. The system preferentially adsorbs oxygen over nitrogen, enabling efficient gas separation. PLC-controlled pneumatic valves alternate between two adsorption towers to maintain continuous nitrogen production.

The complete system includes an air compressor, refrigerant air dryer, filtration system, main nitrogen generator, and buffer tanks for both air and nitrogen. For higher pressure requirements, an optional oil-free nitrogen compressor can be integrated.

• Food industry: Nitrogen flushing for food preservation and beverage processing
• Pharmaceutical: Nitrogen protection for injection solutions and medical fluids
• Chemical industries: Applications in polyurethane, rubber, plastics, and biotech
• Electronics manufacturing: Soldering, electronic components, and battery production

• Optimized process flow minimizes compressed air consumption
• Premium molecular sieve ensures maximum energy efficiency
• Intelligent load adaptation technology for additional energy savings
• Advanced air purification extends CMS lifespan and adsorption efficiency
• Patented valve technology guarantees operational stability
• Dual buffer tank system ensures consistent gas supply
• Remote monitoring and control capabilities

The PSA process utilizes two CMS-filled vessels operating in alternating cycles:

1. Adsorption: Compressed air passes through CMS, adsorbing oxygen while nitrogen passes through
2. Desorption: Saturated CMS bed regenerates while the second vessel takes over production
3. Regeneration: Purge nitrogen from the active vessel regenerates the saturated CMS
