FAQ
What is a PSA nitrogen generator?
A PSA (Pressure Swing Adsorption) nitrogen generator is an on-site gas production unit that extracts nitrogen directly from compressed air. Equipped with two adsorption towers filled with carbon molecular sieve, it adsorbs oxygen, carbon dioxide, and moisture from compressed air, delivering a continuous supply of high-purity nitrogen.
What is included in a nitrogen generator system?
A whole PSA nitrogen/oxygen generator system includes an air compressor, air receiver tank, multiple filters, air dryer, activated carbon filter, PSA nitrogen/oxygen generator, and buffer tank. An oxygen analyzer or purity sensor continuously monitors gas purity and automatically vents out-of-specification gas.
How does a PSA nitrogen plant work?
Based on the Pressure Swing Adsorption principle, the plant uses pressurised-adsorption and depressurised-desorption with dual-tower alternating cycles for continuous production of high-purity nitrogen. While one tower generates nitrogen, the other releases trapped gases and regenerates the sieve material.
What is the benefit of an on-site nitrogen generator?
On-site nitrogen generation provides high-purity output up to 99.999% with adjustable purity, on-demand gas supply without handling heavy gas cylinders or liquid nitrogen deliveries, and long-term cost efficiency compared with purchasing bulk gas.
How to choose the nitrogen purity of an on-site nitrogen generator?
95%-98% is suitable for fire protection, marine tank blanketing, oil field pipeline purging, and tyre inflation. 99%-99.9% suits food and beverage modified atmosphere packaging and conventional plastic molding. 99.95%-99.99% is applied in mild-steel laser cutting, electronics, cable production, and pharmaceutical blanketing. 99.999% and above is required for cutting special metals such as titanium alloy, high-end electronics, and specialized laboratories.
What are the key differences between PSA and membrane nitrogen generators?
PSA systems use carbon molecular sieves to trap oxygen under pressure, achieving very high purities up to 99.999%. Membrane systems use hollow-fiber bundles to filter gases by permeation speed, offering lower purities (95% to 99.5%) in a compact, quiet design.
