PSA Nitrogen Generator

As the name implies, the PSA nitrogen generator adopts pressure swing adsorption technology to separate the nitrogen from the air. Through depressurization, the nitrogen will be desorbed.

System Construction
The nitrogen generating machine is composed of air compressor, air pretreating equipment (refrigerated air dryer and filter), air buffer tank, nitrogen generator, and nitrogen buffer tank.

Workflow
1. Firstly, the air pretreatment is carried out to eliminate the steam, dust, and oil contamination contained in the compressed air.
2. The processed air will then enter the two adsorption towers of the PSA nitrogen generator.
3. The carbon molecular sieve adsorbs the oxygen molecule in the air. Most of the nitrogen molecule will be collected and delivered to the nitrogen buffer tank for use.

Advantages
1. The two adsorption towers for the high purity nitrogen generators work alternatively and automatically, ensuring continuous nitrogen production.
2. The operation of the switch is controlled by PLC installed for the air separation equipment.
3. Smartly designed, the solenoid valve for the PSA nitrogen generator is connected to the air source driven valve and the pneumatic valve. Through PLC, the signal is sent to control magnetism reversal, realizing automatic operation of the pneumatic valve.
