How it works:


Air from an external source enters the generator via a 0.01-micron filter [1] that removes contaminants and bulk moisture via an integrated auto drain. When the control system assesses that more nitrogen is required, the solenoid valve [2] is opened and pressure is allowed to build in the column [4] containing Carbon Molecular Sieve (CMS) and a residue moisture catcher [3].This sieve adsorbs the oxygen and leaves the dry nitrogen free to flow through the non-return valve into the direction of the variable reservoir capacity (VRC) [7] Following on from this the Nitrogen is allowed to flow to the application via another 0.01-micron filter [8] and pressure and flow regulators [9].The trapped oxygen is meanwhile filtered out through the exhaust valves [6]

An on-site nitrogen generator provides several benefits over bottled gas:

  • Save money: You never have to pay for bottled nitrogen again.

  • Save space: A nitrogen generator requires less space than storing gas cylinders.

  • Improve workplace safety: Employees don’t have to move heavy gas cylinders, nor                                                                                        do you have to store high-pressure tanks.

  • Reduce delays: You don’t have to wait for deliveries of bottled gas.


  • Mass Spectrometry (LCMS instruments)

  • Drying Gas & Shield Gas

  • Fibre Optics

  • Blanket gas for Ovens

  • Special Coatings

  • Wave Soldering

  • Packaging
