PSA Nitrogen Generation System for Reliable On-Site Nitrogen Supply
Dec 08 , 2025
Factories require nitrogen for stable and safe production. Thus many companies adopt the PSA nitrogen generation system to have on-site nitrogen. This system cuts the cost of gas and enhances efficiency. It also produces nitrogen on demand with simple operation. Since plants desire independence from delivered cylinders, PSA technology rapidly develops worldwide.
Nanjing Bangwin Gas provides advanced on-site nitrogen systems to global users. Discover more at https://bangwingas.com/ .
PSA nitrogen generation system is a piece of equipment to separate nitrogen from compressed air. It features a specific adsorbent named CMS to adsorb oxygen and other gases. The PSA system offers nitrogen purity of 95% to 99.999%. Hence the system is applicable to various industries that demand high purity.
Companies choose PSA systems because the solution reduces cost and increases safety. Users also benefit from the long service life and stable output.
PSA nitrogen generation system operates in two towers. Cycle switching is quick for continuous flow of nitrogen.
Step 1: Adsorption
Compressed air feeds the tower and CMS adsorbs oxygen. Nitrogen then flows from the tower to the buffer tank.
Step 2: Equalization
Pressure between towers equalizes to minimize power consumption.
Step 3: Desorption
The system then desorbs oxygen from CMS. This results in a purging process that cleans the tower.
Step 4: Regeneration
Tower is ready for next cycle.
Cycle is short and repeated all day. Thus, nitrogen output is always stable and continuous.
PSA nitrogen generation system has the following benefits for industries:
Low operating cost
The system does not need to buy gas cylinders, it will also save transportation costs.
Stable nitrogen purity
It can provide stable and controlled purity to meet the needs of sensitive processes.
Fast start and stop
PSA system can quickly achieve set purity within a few minutes.
Safe and clean gas
Dry and oil-free nitrogen will be provided for users.
Compact structure
Small footprint and easy installation is supported by the design of the system.
Continuous supply
Nitrogen is generated by the system as long as the plant requires.
High reliability
The CMS material of the system can have a long service life and low wear loss.
As such characteristics allow to maintain stable production, PSA systems have been used for a long time in many industries.
