IATT are proud providers of a range of pressure swing adsorption, or PSA, nitrogen generators, in fact, it’s one of our speciality products in terms of install, supply, and servicing. It’s an incredibly intelligent piece of equipment, as the technology of PSA Nitrogen Generators produces nitrogen with a high purity of up to 99,9999% with 1.0 ppm residual oxygen. Not only this, but they also cover flow rates from a few Nm3/hr to over 10,000 Nm3/hr.
In many ways they are similar to Membrane systemsbecause PSA nitrogen generators too are designed as free standing modular systems. This makes for easy integration into new or existing plant installations which makes them not only incredibly effective as a product, but versatile and suitable for a wide range of applications for industrial and commercial operations and sites.
IATT supply, install, and service all products listed on our website, including PSA nitrogen generators, using our dedicated team of factory trained engineers strategically located throughout the UK.
Our engineers are in perfect position to assist you and your business when it comes to all of the various technologies, products, and services we provide at IATT. From supplying to installation as well as general maintenance and regular servicing, we can guarantee not only a smooth operation when it comes to our products and services, but an incredibly high level of customer service throughout the process.

The technology of PSA Nitrogen Generators produces nitrogen with a high purity of up to 99,9999% with 1.0 ppm residual oxygen covering flow rates from a few Nm3/hr to over 10,000 Nm3/hr. Like Membrane systems, these PSA Nitrogen Generators are also designed as free standing modular systems for easy integration into new or existing plant installations. This gives you that added versatility and choice around the system and positioning of said system to best benefit your operations.
PSA technology is advanced and based on the adsorption principle, which is as follows: nitrogen and oxygen molecules from the intake atmospheric air are separated by a carbon molecular sieve (CMS). The larger nitrogen molecules penetrate the system as they are not adsorbed by the activated carbon of the CMS. The nitrogen is then passed to the downstream nitrogen buffer tank system tank where the high purity nitrogen is ready to use.
IATT PSA Nitrogen Generators can be equipped as standard with touch control panels, modular expansion options and low maintenance valve technology. This means they are not only incredibly effective, but also easy to use and efficient, saving you time and money and boosting your operations substantially.
PSA Nitrogen Generation is carried out using the adsorptive properties of adsorptive media such as a Carbon Molecular Sieve (CMS) or Zeolite. Oxygen and other trace gasses are preferentially adsorbed onto the adsorptive media at varying portions, depending on the system pressure, while the nitrogen passes through due to its molecular structure being too large to penetrate the fine porosity of the adsorptive media.
The system uses two pressurised twin towers to contain the adsorptive media where the clean dry compressed air enters at the bottom of one of the towers. Oxygen and trace gases are adsorbed and nitrogen passes through the adsorbent media bed into a buffer tank prior to the outlet, further filtration and then onwards via the pipework distribution system to the process. After a predetermined time, dependant on the purity of nitrogen, the tower switches to regenerative mode and flows the pressurised compressed air into the second tower (hence the term Pressure Swing) where the process starts again. The first tower then depressurises and the adsorbed oxygen and other trace gases are released and exhausted to atmosphere.
In a gas application such as nitrogen generation, adsorption is the accumulation of molecules of oxygen and other trace gases to form a thin film on the surface of a specifically selected solid such as carbon or Zeolite by intermolecular forces – the adsorption process is reversible which facilitates the constant use of the system to generate nitrogen on a commercially viable scale.
A number of PSA (Pressure Swing Adsorption) twin tower units can be piped or manifolded together into a larger unit to enable high flow capabilities.
