PSA Nitrogen

German Technology from CarboTech AC GmbH. Technology. Delivered by MVS. PSA Nitrogen Generators are the most economical and reliable way of producing high purity Nitrogen gas at your own premises and take control of your gas supply for your process.

Technical Facts


Flow Range

PSA Nitrogen Generators are suitable for flows from 1 nm3/hr to 1500 nm3/hr. Higher flows can be reached by using multiple PSA units.


Oxygen Purity

Purity from 98% to 99.999% is possible directly with a simple PSA unit. For higher purity – ppm-level oxygen content, we recommend using our DX or Copper-DX models which guarantee the highest purity levels up to 99.9999%.



Our PSA Nitrogen Generators can deliver nitrogen directly as high as 10 kg/cm2g pressure without an additional booster, making is suitable for most applications. Though most customers will find a system offering nitrogen at 5 kg/cm2g pressure quite suitable. Pressure selection is important from an energy efficiency viewpoint.


Dew Point

Our Nitrogen Generators deliver very dry gas, with dew point as low as (-) 80°C. We also offer measuring instruments for online detection of gas dryness.

How it works?

GERMAN technology – Precision and reliability.

We are the technology licensees of CarboTech AC GmbH since 1984. CarboTech is the world’s most reputed and renowned supplier of PSA technology.

PSA, short for Pressure Swing Adsorption, is a mature technology perfected in the 1970s by CarboTech and millions of PSA units are operating worldwide. Atmospheric air comprises of 78% nitrogen and the PSA process utilizes Carbon molecular sieves to extract this Nitrogen from air. High purity nitrogen is delivered, while the oxygen adsorbed by the molecular sieves is vented back into air through the exhaust line.

PSA process consists of 2 vessels filled with Carbon Molecular Sieves (CMS) and Activated Alumina. Clean compressed air is passed through one vessel and nitrogen comes out as product gas. The exhaust gas (Oxygen) is discharged back into atmosphere. Upon saturation of the molecular sieve bed, the process switches Nitrogen generation to the other bed by automatic valves, while allowing the saturated bed to undergo regeneration by depressurization and purging to atmospheric pressure. Thus 2-vessels keep cycling alternately in Nitrogen production and regeneration ensuring Nitrogen gas is continuously available to your process.




For producing nitrogen with purities up to 99.999%. Very simple unit.



For purities with oxygen levels of 1-3 ppm (max). Hydrogen can be modulated as per customer needs and can be in concentration of 0.5% or higher. Suitable for heat treatment applications.


Copper DX (CU-DX)

For ultra-high purity, with oxygen level at 1 ppm (max). Hydrogen is also NIL. Suitable for processes that cannot absolutely tolerate any oxygen in their application. This model is selected for very specific applications.


Our PSA Nitrogen Gas Generators are widely used across many industries including:

  • Tyre filling (Automotive, Aircrafts, Dumpers, Mine Trucks)
  • Fuel Tank Inerting (Petrochemical Complexes, Chemical Factories, Aircrafts)
  • Autoclaves and Furnaces
  • Blanketing for many industries (adhesives, pesticides, agro, pharmaceuticals)
  • Metal processes (heat treatment, annealing, sintering)
  • Fire prevention (cement, coal mines, mines)
  • Oil & Gas and Petrochemicals (Pigging, Blanketing, Headspace filling, Pipeline drying)
  • Laboratories (LCMS, Turbo Vap, GC, GCMS)
  • Offshore Platforms & FPSOs
  • Oil cargo ships and oil tankers
  • Flex printing
