Nitrogen Generation

Many applications exist for on-site Oxygen and Nitrogen generation, across various industries. The benefits of generating these gases are numerous, not least the considerable cost saving and simplified logistics.


Pressure Swing Adsorption can be used to produce N2 or O2 from compressed air, which is fed to the unit that uses adsorption phenomena to remove the contaminants: N2 when the desired pure gas is O2, or O2 when the desired pure gas is N2.  Also, in both cases, H2O and CO2 are removed as well as other minor contaminants.

The PSA unit contains two columns packed with a selective adsorbent that has affinity towards the component to be removed: a carbon molecular sieve is used to produce N2 and zeolites are used to produce O2.

Each column undergoes a cyclic sequence of high and low pressure steps that guarantees the production of a continuous flow of high purity gas.

In the high pressure step, the adsorbent retains the contaminants present in the compressed air and the desired gas (N2 or O2) is obtained from the top of the columns.

The regeneration is accomplished in the low pressure step, with the release of contaminants retained by the adsorbent.

NITROGEN – A line of robust, reliable and modular Nitrogen generators based on Pressure Swing Adsorption (PSA) technology using state of the art Carbon Molecular Sieves adsorbents.

  • Reduction of Nitrogen costs up to 95%
  • Independence from external gas suppliers and from fluctuation of the Nitrogen market prices
  • Suppression of logistic operations like handling of cylinders or liquid Nitrogen supplier management
  • Modular, flexible and low maintenance units
  • Nitrogen pressure up to 9 bar (without Booster)
  • LCD display
  • Oxygen analyzer
  • 4.0 Ready
  • Purity up to 99.999%
  • VARIO PSA (optional)


Nitrogen is designed to be easily installed in any indoor facility, requiring only a compressed air line and a power connection. Our modular philosophy of Nitrogen generators allows the installation of multiple parallel units.

SYSADVANCE generators produce high purity Nitrogen from compressed air, allowing continuous availability at a very competitive cost, compared to alternative supply with cylinders or cryogenic tank.

With purities up to 99.999% of N2, Nitrogen can be connected to an external buffer allowing a backup or a delay of production/consumption according to the needs of each application.
