nano nitrogen generators

Generating an endless supply of nitrogen gas at your facility can be achieved in two ways: pressure swing adsorption (PSA), or membrane separation.  The selection of which technology to apply will vary greatly with each application and is highly dependent on how the nitrogen is being used.  Purity Gas is a proud supplier of nano nitrogen generators, specializing CSA certified, PSA and membrane nitrogen gas generation systems.  Purity Gas offers a no charge preliminary assessment and site visit, to help determine the most appropriate system design and equipment selection for your specific application.    

Pressure Swing Adsorption (PSA)

Nitrogen Generation technology

PSA is a process in which compressed air is passed through a bed of carbon molecular sieve (CMS), which is stored in multiple chambers, side by side.  The CMS is designed to capture oxygen and trace gases, while allowing the larger nitrogen molecule to flow past the CMS and out of the nitrogen generator.  The PSA nitrogen generator is a self regenerating system and is divided into two chambers: side A and side B.  These chambers work in tandem to separate gases, regenerate the CMS and equalize pressure.  While chamber A of the generator is under pressure, actively separating nitrogen from the air, chamber B is off duty and regenerating.  The CMS in chamber B will regenerate using a small percentage of nitrogen gas siphoned from chamber A.  Once the CMS in chamber A is saturated with oxygen and trace gas, the chambers will exchange gas separation and regeneration duties.  Chamber B, which is now regenerated and ready for duty, will become the active chamber for oxygen and trace gas adsorption. Chamber A, will now cleanse itself of the oxygen and trace gas impurities, which were collected in the CMS during the gas separation process.  The PSA gas separation process will create a constant, consistent and uninterrupted flow of nitrogen gas at an extremely high purity.

The nano GEN2 PSA nitrogen generator will deliver nitrogen gas ranging from 95% to 99.999% purity, at any flow required.  Nano nitrogen generator’s sleek and modular design will allow for seamless expansion of nitrogen supply, with minimal installation and effort. The GEN2 modular and multi-bank arrangement will also create cost-effective system redundancy, without having to purchase a complete second system.  Each bank is supplied with a dedicated PLC for uncompromising system communication.  GEN2 multi-bank communication is designed with energy conservation in mind during low demand periods.  As the nitrogen needs of the facility fluctuate, GEN2 banks will come online to satisfy immediate flow requirements during high demand periods, while going off line to conserve energy and reduce wear and tear during low demand periods. The touch screen PLC displays real-time nitrogen purity, pressure, operating hours and column operation.  The PLC contains digital and analog outputs for remote monitoring and alarm capabilities.  The nano GEN2plus model features an integrated purification system, eliminating the need for an external desiccant dryer and minimizing purge loss by 20%. nano’s GEN2 PSA generators are backed by a comprehensive two-year manufacturer’s warranty and also include a two-year no charge preventative maintenance plan when purchased from Purity Gas.

The nano ECOGEN2 and VIN2 PSA nitrogen generators are compact plug and play solutions.  These products will deliver an on demand supply of nitrogen gas, ranging from 95% to 99.9% purity.  The ECOGEN2 and VIN2 for wine production simply require pre-treated compressed air to the inlet of the generator, and can be installed with minimal cost and interruption. The nano ECOGEN2 and VIN2 PSA generators are backed by a comprehensive two-year manufacturer’s warranty and also include a two-year no charge preventative maintenance plan when purchased from Purity Gas.

Membrane Separation

Nitrogen generation can be achieved using membrane technology.  Similar to pressure swing adsorption (PSA), nitrogen is isolated from the other gases using a separation process.  Membrane separation is achieved by passing compressed air through thousands of hollow fibers, which are designed to separate nitrogen from oxygen and trace gases.  While the compressed air travels down the hollow fibers, the oxygen and trace gases permeate through the fiber walls, allowing only nitrogen continue down the fiber tubes and out of the discharge port.  This separation process is called selective permeation.

The nano NMG membrane nitrogen generator is supplied as a complete, pre-piped package, including four-stage filtration and drains.  The nano NMG nitrogen generator has no moving parts and is virtually silent during operation. The NMG membrane generator will deliver enriched nitrogen gas ranging from 95% to 99.9% purity.  Due to the NMG’s compact design, this nitrogen generator is a perfect solution where floor space is limited.  The NMG series membrane generator can be installed horizontally or vertically, providing tremendous flexibility for installation.  Once a clean supply of compressed air is connected directly to the inlet of the NMG generator, nitrogen gas will start to flow.  The nano NMG membrane generator is backed by a comprehensive one-year manufacturer’s warranty and includes a one-year no charge preventative maintenance plan when purchased from Purity Gas.
