The PSA Nitrogen Generator uses Pressure Swing Adsorption (PSA) technology to separate nitrogen from compressed air and provide a stable on-site nitrogen supply. The system is equipped with two adsorption towers filled with high-performance carbon molecular sieve (CMS), which selectively adsorbs oxygen while allowing nitrogen to pass through as the product gas.
During operation, compressed air enters one tower, where oxygen molecules are captured by the CMS and nitrogen is collected at the outlet. At the same time, the second tower enters the regeneration stage, releasing the adsorbed oxygen into the atmosphere together with a small amount of nitrogen.
When the first tower reaches adsorption saturation, the system automatically switches. The regenerated tower begins nitrogen production, while the saturated tower starts regeneration. Controlled by a PLC automatic control system, the two towers work alternately in a continuous cycle, ensuring stable nitrogen purity, reliable performance, and uninterrupted nitrogen output.
To ensure stable nitrogen purity and efficient long-term operation, the PSA Nitrogen Generator should be used under the following recommended conditions:
- Inlet temperature: ≤ 40℃
- Inlet pressure: 0.5–0.8 MPa
- Nitrogen purity: 95%–99.999%
- Nitrogen dew point: ≤ -40℃
- Ambient temperature: ≤ 40℃
- Switching cycle: 45–60 seconds
- Voltage / frequency: 220V / 50Hz
- Noise level: ≤ 75 dB
For the best operating result, the generator should be supplied with clean and stable compressed air. Proper pre-treatment, including air filtration and drying, is recommended to protect the carbon molecular sieve, maintain nitrogen purity, and extend equipment service life.
