3.   Product Description

3.1   Technical Specification

The nitrogen generator operates on the Pressure Swing Adsorption (PSA) principle to produce a continuous 

stream of nitrogen gas from clean dry compressed air. 

Pairs of dual chamber extruded aluminium columns, filled with Carbon Molecular Sieve (CMS), are joined via 

an upper and lower manifold to produce a two bed system. Compressed air enters the bottom of the ‘online’ 

bed and flows up through the CMS. Oxygen is preferentially adsorbed by the CMS, allowing nitrogen to pass 

through. 

After a pre-set time the control system automatically switches the bed to equalization mode where the online 

bed pressure is equalized with the second regenerated bed. Once equalized the online bed is switched to 

regenerative mode and oxygen is vented from the CMS. A small portion of the outlet nitrogen gas is expanded 

into the bed to accelerate the regeneration. At the same instant the second bed comes on-line and takes over 

the separation process. 

The CMS beds alternate between online equalization and regeneration modes to ensure continuous and 

uninterrupted nitrogen production. 

When a generator is specified with an internal dryer, each CMS column has a unique adsorption media tube  

technology dryer fitted into the bottom of each column.

The unique intergrated dryer does not require servicing and the life is aligned to the CMS material. 

The intergrated dryer reduces energy running costs by eliminating the additional external dryer purge (typically 

20%  of  the  dryer  inlet  air  consumption)  and  the  associated  pressure  loss  across  an  external  dryer.  The 

compressed air requirement is also reduced accordingly.

The oxygen concentration in the nitrogen stream is monitored continuously on models fitted with an oxygen 

analyzer. If the outlet concentration exceeds the required production level, the nitrogen outlet is closed and the 

gas is vented to atmosphere. Normal operation will resume when the purity recovers.
