nGEN – Industrial Nitrogen Generator for On-Site PSA Nitrogen Production
Absstem’s nGEN Industrial Nitrogen Generator is a PSA-based on-site nitrogen generation system built for manufacturing plants that require continuous, high-purity nitrogen without cylinder or liquid nitrogen dependency. Unlike packaged machines, nGEN is delivered as a fully engineered, installed, and commissioned PSA nitrogen system that supplies nitrogen directly to your production lines at the required purity, pressure, and flow. It is trusted across food processing, pharmaceuticals, Semiconductor, electronics, metal fabrication, laser cutting, tyre manufacturing, oil and gas, power plants, 3D printing, and chemical industries where nitrogen quality and uptime directly impact product performance and cost.
What is an Industrial Nitrogen Generator?
An industrial nitrogen generator is a system that produces nitrogen on-site from atmospheric air using Pressure Swing Adsorption (PSA) technology. It replaces cylinders and liquid nitrogen by delivering continuous, on-demand nitrogen directly to the plant.
nGEN is Absstem’s industrial-grade PSA nitrogen generator, designed for 24×7 manufacturing environments.
How PSA Nitrogen Generator Works
Air Intake & Purification
Ambient air is filtered, dried, and compressed to remove moisture, dust, and oil.
PSA Nitrogen Separation
Carbon molecular sieves adsorb oxygen while allowing nitrogen to pass through.
Nitrogen Storage & Delivery
Nitrogen is stored in buffer tanks and supplied to your process pipelines.
Automated Control
PLC-based automation with IIoT monitoring ensures stable purity and low operating cost.
Typical Performance of PSA Nitrogen Plant

FAQs – nGEN (Industrial Nitrogen Generator)
Is nGEN a nitrogen generator or a nitrogen plant?
nGEN is a PSA nitrogen generator delivered as a complete on-site nitrogen plant. It includes air compressors, PSA nitrogen generation modules, storage tanks, controls, installation, and commissioning. At Absstem, nGEN is supplied as a fully engineered nitrogen system, not just standalone equipment.
How does a PSA nitrogen generator work?
A PSA nitrogen generator works by separating nitrogen from compressed atmospheric air using carbon molecular sieves. Oxygen and trace gases are adsorbed, while nitrogen passes through and is collected in storage tanks. The system operates automatically in cycles to deliver continuous, on-site nitrogen at the required purity, pressure, and flow for industrial processes.
Can nGEN replace nitrogen cylinders and liquid nitrogen completely?
Yes. nGEN is designed to act as the primary nitrogen source for industrial operations. It eliminates cylinder handling, refilling delays, storage risks, and dependence on external nitrogen suppliers while providing uninterrupted 24×7 nitrogen supply.
What nitrogen purity and flow can nGEN deliver?
nGEN can deliver nitrogen purity from 95% up to 99.9995%, with flow capacities up to 3000 Nm³/hr, depending on the application. The system is engineered based on actual process demand to ensure stable purity, pressure, and flow.
Which industries are best suited for nGEN industrial nitrogen generators?
nGEN industrial nitrogen generator is widely used in food processing, pharmaceuticals, electronics, semiconductor manufacturing, metal fabrication, laser cutting, chemical plants, oil & gas, power plants, and tyre manufacturing-where nitrogen quality, uptime, and cost control are critical.
How is nGEN different from compact or packaged nitrogen generators?
Unlike packaged nitrogen generators, nGEN is delivered as a fully installed and commissioned PSA nitrogen system. It is designed for continuous industrial duty, higher flow rates, scalable capacity, and long-term reliability, making it suitable for large manufacturing plants rather than intermittent or small-scale use.
