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

PSA technology separates oxygen from ambient air under high pressure, removing nitrogen and other gases through an activated carbon molecular sieve.

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