NitroGenerator-LCMS is a state-of-the-art expandable nitrogen generation system with a built-in standby system which ensures the most efficient use of electricity and the systems internal components. The system uses a compressed air source that can be existing or supplied along with the generator. The compressed air enters the generator via a 0.01-micron filter (1) that removes contaminants and bulk moisture via an integrated autodrain. When the control system assesses that more nitrogen is required the, solenoid valves (2) opens allowing air to enter the Carbon Molecular Sieves (CMS) column (3). After a set duration, the programmable logic controller (PLC) within the control system exhausts the first column and operates another valve to pressurise the second Carbon Molecular Sieve (CMS) column (4). This cycle repeats whilst the application requires nitrogen. The sieve adsorbs the oxygen and leaves the nitrogen free to flow into the reservoir (5). After this point Nitrogen is allowed to flow to the application via pressure and flow regulators (6).
