PSA Nitrogen Generator
Under a certain pressure, utilizing, the principle of the difference in diffusion rates of oxygen and nitrogen in the air on carbon molecular sieves, oxygen molecules are rapidly adsorbed by carbon molecular sieves, and nitrogen molecules are enriched in the gas phase to achieve oxygen and nitrogen separation.
Our company adopts a two-tower adsorption process for nitrogen equipment based on the characteristics of pressure swing adsorption, with one tower adsorbing to produce nitrogen and the other tower desorbing for regeneration. Cyclic alternation continuously produces high-quality nitrogen.
The adsorption capacity of carbon molecular sieves for oxygen varies significantly with the gas pressure. By reducing the pressure, the adsorbed oxygen molecules in carbon molecular sieves can be desorbed. Regenerate the carbon molecular sieve to achieve repeated recycling of the carbon
molecular sieve.
We provide high-quality solutions for nitrogen production systems.
With our proven technical capabilities and insights into the application processes of various industries, we can provide you with customized nitrogen generation equipment design, installation, and application solutions, and provide after-sales services during the operation of the equipment to quickly solve user problems and ensure the long-term, stable, and reliable operation of the nitrogen generation equipment.

PSA Nitrogen Generator Advantages
Adsorption Tower Structure Technology
Enhance molecular sieve efficiency and equipment performance with a unique adsorption tower design that optimizes airflow, reduces dead space, and prevents damage. This increases sieve lifespan and adsorption performance while lowering energy consumption.
Molecular sieve filling
The patented microwave oscillation filling technology makes the molecular sieve filled more evenly and densely, ensuring that the molecular sieve does not produce a fluidized state during the adsorption process, and there is no need to regularly replenish expensive carbon molecular sieves.
Clamping device
It adopts advanced cylinder compression technology. Under working condition, the piston always ensures that the molecular sieve is compressed, and at the same time, the carbon molecular sieve will not be crushed, thus avoiding the molecular sieve powdering caused by high-speed airflow impact.
Adsorbent
Adsorption materials are selected from international famous brands such as Germany's Capo, Japan's Takeda, Japan's Iwatani or domestic well-known brands according to customer needs, with a normal service life of up to 10 years, ensuring the quality, purity and life of nitrogen.
Valve
The valves are made of BURKERT valves imported from Germany or domestic well-known brands according to customer needs. The response speed is 0.02 seconds, the service life is more than 3 million times, and it has the characteristics of simple structure and reliable sealing.
Intelligent controller
The Siemens brand intelligent controller - Siemens PLC programmable controller and solenoid valves from major brands such as Germany's BURKERT and Taiwan's AirTac are selected to ensure the continuous and reliable operation of the nitrogen generator.
Nitrogen Generator Plant Informations
1. Air compression
Air compressor: compresses ambient air to a high pressure state. The compressed air contains nitrogen, oxygen, carbon dioxide and other gases.
2. Air pretreatment
Cooler: cools the compressed air to remove moisture in the subsequent steps.
Dryer: removes moisture from the compressed air by freeze drying or adsorption drying.
Filter: removes solid particles and oil mist from the compressed air.
3. Separation of nitrogen
Pressure swing adsorption (PSA): separates oxygen and nitrogen by using the adsorption characteristics of molecular sieves for oxygen and nitrogen at different pressures. Nitrogen passes through the molecular sieve, while oxygen is discharged.
4. Nitrogen storage
Gas storage tank: stores the separated nitrogen in a high-pressure gas storage tank for subsequent use.
5. Nitrogen regulation
Pressure regulation: adjust the output pressure of nitrogen to meet the needs of different applications.
Flow control: control the flow of nitrogen to ensure a stable supply.
6. Nitrogen delivery
Pipeline system: transport nitrogen through pipelines to places where nitrogen is needed, such as industrial production lines, laboratories, etc.
