Nitrogen Generators

The cost-effective, reliable and safe solution for medium to large nitrogen requirements.

CompAir offers an ideal solution with a comprehensive range of cost effective nitrogen generator systems from compressed air, that enable users to produce their total demand for nitrogen gas on their premises and under their control.

Compared to traditional methods of supply, on-site nitrogen generator is exceptionally cost-efficient with a short payback time on investment - in many cases less than twelve months.

What is a Nitrogen Generator and how does it work?

The air we breath is approximately 78 percent nitrogen and 21 percent oxygen, a small amounts of other gases, such as neon, and hydrogen make up the other 1%. A nitrogen generator is able to produce a continuous uninterrupted stream of nitrogen gas from clean dry compressed air. It uses a Carbon Molecular Sieve (CMS) bed where oxygen and other trace gases are preferentially adsorbed and the nitrogen is allowed to pass through.

Dual chamber system

Extruded aluminium columns are filled with Carbon Molecular Sieve (CMS). Joined via an upper and lower manifold, the high density filled columns produce a dual bed system. After a pre-set time the control system automatically switches the beds. One bed is always online generating nitrogen while the other is being regenerated. During regeneration, the oxygen that has been collected in the CMS stage and the moisture that has been collected in the optional integrated dryer stage are exhausted to atmosphere. A small portion of the outlet nitrogen gas is expanded into the bed to accelerate the regeneration process.
