On-site PSA Nitrogen Generator offers convenience for your industrial applications. The machine can be started as long as it is connected to the 230v/50hz power supply, eliminating the need for constant monitoring. With air as the raw material—available in abundance—PSA technology offers a 10-20% reduction in obtaining nitrogen costs, The PSA nitrogen generator is sufficient to meet your production line’s nitrogen demands.
The principle of a Pressure Swing Adsorption (PSA) Nitrogen Generator is to separate nitrogen gas from compressed air and convert it into the nitrogen capacity, purity, and pressure specifications you require. The PSA method is a cost-effective alternative to cryogenic air separation, dewar bottles, and bottled nitrogen. PSA eliminates safety and operational issues associated with high-pressure cylinders.

What is a Pressure Swing Adsorption (PSA) Generator?
A Pressure Swing Adsorption (PSA) nitrogen generator is designed to produce nitrogen gas directly on-site. Utilizing the PSA process, which uses molecular sieves to adsorb oxygen from compressed air, efficiently separates nitrogen from the air, delivering a high-purity nitrogen gas stream. The nitrogen produced is then passed through a buffer tank to stabilize the flow speed. PSA generators offer a practical, cost-effective solution to on-demand nitrogen production with minimal ongoing operational costs.

How Does an Industrial PSA Nitrogen Generator Work?
Industrial PSA nitrogen generators work by compressing ambient air and passing it through a series of adsorption towers filled with molecular sieves. The sieve selectively adsorbs oxygen and other impurities, allowing the nitrogen to pass through. The system then separates the nitrogen from the air, based on pressure variations, in a process called pressure swing adsorption. The nitrogen gas is then purified and delivered at the desired purity and pressure to your industrial applications. This efficient method ensures a reliable and cost-effective nitrogen supply without the need for external nitrogen cylinders.

What is a PSA Tower in a Nitrogen Plant?
A PSA tower, or adsorption tower, is a key component of a PSA nitrogen generator. These towers are filled with molecular sieve material, which is designed to adsorb oxygen and other gases present in the compressed air. During the PSA process, air is directed into the tower at high pressure, where the sieve material selectively adsorbs oxygen molecules, allowing the nitrogen to pass through. Once the sieve material becomes saturated with oxygen, the pressure in the tower is reduced, and the oxygen is released. This cycle is repeated to continuously produce high-purity nitrogen gas for your industrial applications.
In our design process, we can make double-tower, four-tower, and other multi-tower structures according to customer demand, which can save space and cost based on meeting the customer’s large nitrogen capacity needs.
In conclusion, PSA nitrogen generators from BODA GAS provide a reliable, cost-effective, and efficient solution for on-site nitrogen production. With over 23 years of industry experience, we are committed to delivering high-quality products that meet your specific needs.
