What is CMS (Carbon Molecular Sieve Material)?
Pressure swing absorption (PSA), technology uses columns of carbon molecular sieve, (CMS), to separate compressed air. Oxygen and other waste gasses are selectively absorbed under pressure by the CMS, allowing nitrogen to pass through the application. The CMS is regenerated by releasing the pressure in the columns and venting the waste gasses to the atmosphere.

PSA SYSTEM
*The NITROSource PSA range of nitrogen generators operate 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. Whilst one bed is online and removing oxygen from the process air the other is regenerated.
*Clean, dry particulate free compressed air enters the bottom of the online bed and flows up through the CMS. Oxygen and other trace gases are preferentially adsorbed by the CMS, allowing nitrogen to pass through.

*At the end of this adsorption phase the inlet, outlet and exhaust valves close on both beds. The upper and lower equalisation valves open, allowing the pressure to equalise between the beds. This equalisation phase is designed to reduce energy consumption and enhance the overall performance of the generator.
*Once equalised the bed entering regeneration is depressurised. The oxygen adsorbed during the adsorption phase is vented to atmosphere via an exhaust valve and silencer. A small proportion of the outlet nitrogen gas is also expanded into this bed to help the desorption of oxygen from the CMS.
*The bed entering the adsorption phase is pressurised using a controlled flow of nitrogen gas from the nitrogen buffer vessel (Back Fill) and a controlled flow of clean, dry, particulate free compressed air (Front Fill).
