Nitrogen generators

We manufacture customised equipment to suit your needs.

A nitrogen generator is an industrial system used to separate nitrogen from other gases in the ambient air, using a compressed air inlet, providing a varying flow and purity depending on the various applications.

Today, PSA and membrane systems are an appealing supply mode for a wide range of volumes, purities and applications. The former are based on adsorption, while the latter are based on selective permeation.

ABSOGER produces two types of nitrogen-generating technologies, in order to fully accommodate the client’s needs: PSA (Pressure Swing Adsorption) technology and membranes.

PSA technology

The PSA technology consists of separating the oxygen from the nitrogen contained in the ambient air at low pressure using a molecular sieve of activated carbons.

  • PSA technology (Pressure Swing Adsorption): Adsorption by pressure variation.
  • Need compressed air drying and purification
  • 2-column generators with CMS activated carbon
  • Continuous generation of stable, high-purity nitrogen.
  • High purity levels (>99.9%).

Gen2ius: Technical specifications

  • Purity of the nitrogen produced: from 95% to 99,999%
  • Nitrogen flow rate: 1 to 130 Nm3/h – higher flow rates available on request
  • Nitrogen outlet pressure: 5 to 330 bar
  • Number of columns can be increased
  • Low energy consumption
  • Long-lasting activated carbons

Gen2ius Range

GA: Technical specifications

  • Purity of the nitrogen produced: from 95% to 99.9999%
  • Nitrogen flow rate: 1 to 2000 Nm3/h – higher flow rates available on request
  • Nitrogen outlet pressure: 5 to 330 bar
  • Low energy consumption
  • Long-lasting activated carbons

Solutions

In PSA systems, the compressed air must be dry and free of impurities before entering the nitrogen generator. ABSOGER has developed a high-efficiency air pre-treatment system installed with PSA nitrogen generators.

GA range: customised skid
All technical features of the skid elements and the unit's instrumentation are customised for each application and each client.
GEN2IUS Range: modular skid
GEN2IUS models adapt to the user's nitrogen needs. By adding CMS columns, the nitrogen flow rate of the GEN2IUS is increased without having to change the generator model.

Membrane Technology

  • Medium or low purity levels (<99.9%).
  • Need a dry air supply
  • Hollow fibre air filtration
  • Selective material permeability

Technical specifications

  • Purity of the nitrogen produced: from 95% to 99.5%
  • Nitrogen flow rate: 1 to 2,000 Nm3/h – higher flow rates available on request
  • Nitrogen outlet pressure: 5 to 330 bar
  • Compact weight and size
  • It is possible to change a membrane without stopping the generator
