GASPU PSA Nitrogen Generator for Industrial Nitrogen Production

The GASPU Pressure Swing Adsorption (PSA) Nitrogen Generator is a cutting-edge on-site nitrogen production system designed to deliver high-purity nitrogen efficiently using air as the primary raw material. Leveraging advanced PSA technology and premium carbon molecular sieves (CMS), this generator separates nitrogen from oxygen by exploiting the selective adsorption properties of CMS, ensuring a continuous, cost-effective supply of nitrogen for diverse industrial needs.

• Advanced PSA Technology: Utilizes two parallel adsorption towers filled with carbon molecular sieves (pore size 0.3nm-1nm) to alternate between pressurized adsorption (oxygen retention) and depressurization regeneration (oxygen release), enabling 24/7 uninterrupted nitrogen flow.
• High Purity & Flexibility: Produces nitrogen with purity ranging from 95% to 99.999% as standard; optional purification modules upgrade purity to 99.9999% for critical applications like electronics or .
• Rapid Startup & Automation: Achieves full nitrogen output in just 15-30 minutes, with a fully automated PLC control system for hands-free operation, reducing labor costs and human error.
• Energy Efficiency: Optimized air compression and regeneration cycles minimize power consumption, lowering operational costs compared to traditional cryogenic separation or cylinder deliveries.
• Compact Design: Modular structure allows easy installation in tight spaces, ideal for small-to-medium enterprises (SMEs) with limited floor area.

• Cost Savings: Eliminates reliance on nitrogen cylinders or liquid nitrogen deliveries, reducing logistics and storage costs by up to 60% over time.
• On-Demand Production: Tailors nitrogen flow rates (0.1-1000 Nm³/h) to real-time demand, preventing waste and ensuring consistent supply.
• Eco-Friendly: Uses air as a raw material (no chemicals or emissions) and low-energy processes, aligning with sustainability goals.
• Low Maintenance: Carbon molecular sieves have a lifespan of 5-8 years, and self-cleaning air filters reduce downtime for servicing.
• Wide Applicability: Suitable for industries including food packaging, electronics, metallurgy, chemicals, and .

Air is filtered, compressed, and purified (oil/water removal) before entering adsorption towers. Carbon molecular sieves adsorb oxygen, leaving nitrogen to flow out. Regeneration depressurizes the tower, releasing adsorbed oxygen to atmosphere--repeating cyclically for continuous nitrogen.

Regular tasks include replacing air filters (every 3-6 months), checking pressure gauges, and inspecting CMS after 5 years. The automated system alerts users to maintenance needs via the PLC interface.

Yes. The generator adjusts production in real time via flow sensors, ensuring stable pressure and purity even during peak usage.

Yes, optional weatherproof enclosures protect components from dust, rain, and extreme temperatures (operating range: -10°C to 45°C).

• Food & Beverage: Inert packaging to extend shelf life of snacks, beverages, and processed foods.
• Electronics: SMT assembly, semiconductor manufacturing, and LCD panel production (prevents oxidation).
• Metallurgy: Annealing, brazing, and powder metallurgy (reduces metal oxidation during heating).
• Chemicals: Inert blanketing for storage tanks, preventing combustion or polymerization of volatile compounds.
