PSA Nitrogen Generator

“Empowering your business with best air quality, performance and solutions”

AirGen Technologies is a primary manufacturer of PSA Nitrogen gas generation Plants. The plant we manufactures are designed to produce nitrogen gas with purity in an impressive range from 99% to 99.999%. AirGen manufactures high-performance, cost-effective and efficient nitrogen gas generators to serve a large group of different applications. PSA Nitrogen Gas Generators facilitates in meeting the onsite gas generation requirements simultaneously eliminates the reliability on traditional methods of nitrogen supply and storage that are also expensive & hard to care.

We believe in providing an efficient solution with least operating costs and superb air purity. With this belief and continuous effort in improving our product design and performance, we have earned the valuable trust of our customers. They are getting their exact requirements of air consumption with the desired flow and purity which is all the users and the suppliers both wants to achieve.

Working of PSA Nitrogen generation plant

By adopting the advanced Pressure Swing Adsorption (PSA) technology, we at AirGen, transform ordinary air into high-purity nitrogen through.  This technology comprises of sequential steps described below.

Air intake and reparation

In this initial process, ambient air (that is mixture of oxygen, nitrogen and other gases) is drawn, compressed and then goes through a series of multiple filters and dryers. This step removes moisture, dust, and other impurities, ensuring that only clean and dry air enters the system.

Separation

This is the fundamental step of PSA nitrogen gas generation process. As the name suggests, this step separates the nitrogen and oxygen gas. Let’s understand how this happens.

The purified air flows into vessels filled with Carbon Molecular Sieve (CMS). Here, oxygen molecules are adsorbed onto the CMS pores due to their smaller size, while nitrogen molecules, being larger, pass unaffected. To provide an uninterrupted nitrogen supply, our system uses two different adsorption vessels that alternate between adsorption and regeneration phases. When one vessel is separating nitrogen, the other is releasing the previously adsorbed oxygen back into the atmosphere. Similarly, when second vessel separates the nitrogen,

first one releases oxygen. This is a continuous cycle that ensures continuous supply of nitrogen at the application place.

Nitrogen collection and supply

The nitrogen produced is stored in a Storage tank with maintained steady pressure and purity level. This stored nitrogen is continuously supplied to the end requirement in the controlled amount.

FAQ

Frequently Asked Questions

Our PSA (Pressure Swing Adsorption) systems deliver ultra-high purity nitrogen ranging from 95% up to 99.999%. Oxygen content can be as low as 1 ppm, and the dew point can reach −80 °C depending on model and configuration.

We integrate online oxygen analyzers to continuously monitor nitrogen purity. If purity drops below the set threshold, the system shuts down automatically and triggers an alert.
