Technical Facts


Flow Range

Suitable for flows from 1 to 1500 nm3/hr. Higher flows can be achieved using multiple PSA units.


Nitrogen Purity

Purity from 98% to 99.999% is possible directly with a simple PSA unit. We recommend using our DX or Copper-DX models for higher guaranteed purity levels up to 99.9999%.



Most customers will find a system offering nitrogen at 5 kg/cm2g pressure quite suitable. However, we can deliver nitrogen directly up to 10 kg/cm2g pressure without a booster compressor.


Dew Point

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

German Technology & Design

Our systems are designed using GERMAN technology from CarboTech AC GmbH.

We have been partners with the inventors of PSA technology – CarboTech since 1984 and continue to exclusively source our CMS (Carbon Molecular Sieves) from CarboTech.

Atmospheric air comprises of 78% nitrogen and the PSA process utilizes CMS to extract this Nitrogen from air.

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.
