The technology used to produce a continuous flow of high purity N2 is pressure swing adsorption (PSA).This technology uses a combination of molecular sieves to selectively eliminate O2 and other contaminants in the ambient air.

The CMS column(s) alternate between the purification and regeneration modes to ensure continuous N2 production. The gas generator is designed to take pre-filtered compressed air at 7 to 18 barg (102 or 261 psi g) (depending on model) from the existing air supply or via a dedicated air compressor.

This flow of filtered compressed air then passes through the CMS column which is in the purification mode. At this point, the O2, CO2, humidity and hydrocarbons are eliminated from the compressed air, producing a flow of clean and dry high purity nitrogen.

Nitrogen purity can range from 95% to 99.999% with flowrates from 1Nm3 to greater than 1000 Nm3. All our systems are modular and can be easily expanded at a later date, depending on demand.
