Nitrogen is a dry, inert gas which is used in many commercial and industrial applications to improve quality or where oxygen may be harmful to the product or processes.

With traditional methods of gas supply such as liquid or bottled nitrogen, users are liable for hidden costs such as rental, refill and delivery, order processing charges as well as an environmental levy charge.

Experience. Customer. Service… nano

"We are so impressed with the operation and performance of the GEN2 units we are looking to add additional modules next year."

A major peanut & snack foods packager in the southeastern US needed to reduce their nitrogen gas costs. They turned to nano-purification solutions and their local authorized nano distributor for assistance. nano worked alongside their distributor with the end customer to design a PSA N2 generation system which reduced nitrogen gas costs from $0.52/100 ft3 down to less than $0.10/100 ft3.
Dual GEN2-12130 units produce an impressive 7840 cfh of nitrogen gas. The modular and expandable design of the nano GEN2 allows for the customer to simply add modular units as their production increases. The integrated energy efficient ecomode function eliminates the costly compressed air requirement during periods of low or no production.

Nitrogen generators use regular compressed air to deliver a continuous supply of high purity nitrogen - offering a cost effective and reliable alternative to the use of cylinder or liquid nitrogen across a wide range of applications.

When you switch to a nano GEN2 gas generator you can expect payback typically between 6 to 24 months. This unique design and energy saving function offers a number of significant advantages over delivered gas options as well as traditional generator designs.

The compact system can be installed easily and with a minimum cost and disruption and requires only a pre-treated compressed air system to start production. An on-site generator enables users to fulfill their demand for nitrogen gas on their premises, under their complete control. As a result, companies can generate as much or as little nitrogen as needed at a fraction of the cost of having the gas delivered by an external supplier.
Dry and Pure N/A Nitrogen is used in many commercial and industrial applications to improve the quality of a product or process or as a safety measure to prevent combustion. Liquid or bottled nitrogen delivery and storage can be expensive, unreliable and a safety concern. Nitrogen generators allow users to produce nitrogen in-house simply and inexpensively using an existing compressed air system.

nano recognizes the importance of having a safe, reliable and cost-effective supply of high-purity nitrogen. We have developed the GEN2 nitrogen generator to meet the increasing demand for high quality complete packaged solutions which save energy and time while fulfilling the needs of their intended application.

Ecomode Energy Saving Control N/A This unique control feature utilizes an outlet pressure monitor to reduce energy consumption during periods of low demand to ensure a continuous uninterrupted nitrogen supply while minimizing power consumption.
PLC Controlled Operation N/A Each GEN2 nitrogen generator is operated by a reliable PLC control system with digital and analog outputs for remote monitoring and alarm capabilities. GEN2 includes an easy-to-operate touch screen graphical interface which offers valuable features including 'power on', 'hours run', 'oxygen purity', 'pressure', 'online column' and 'service required' indicators. In addition, four pressure gauges provide the operator with continuous indication of column A, column B, air inlet and nitrogen outlet pressures.
Multi-Bank Design N/A The unique multi-bank design (GEN2-1110 to GEN2-12130) enables additional generators to be added in the future as demand increases. Your GEN2 nitrogen generator can grow with your company.
Reliable High Performance Valves N/A Inlet, outlet and exhaust are managed through unique integrated nano piston valves, which are designed for reliability, long service life and ease of maintenance. The generator also incorporates adjustable equalization valves which smooth the column switch over, improve air/ N2 ratios and extend CMS life. This highly durable valve system is backed by a comprehensive two-year warranty.

Traditional nitrogen generators often require installing and operating an external desiccant dryer. The innovative nano GEN2plus nitrogen generators feature an integrated dryer cartridge which eliminates the need for a pretreatment dryer of any type. The integrated drying system reduces purge loss by approximately 20% and reduces pressure drop by 10 psi or more which provides significant energy savings over a traditional generator system.
Maximum Corrosion Protection N/A High tensile aluminum columns are first alocromed and then powder coated to provide maximum protection for corrosive environments.
Oxygen Analyzer N/A A built in oxygen analyzer continuously monitors the oxygen concentration in the nitrogen stream. Our NEW remote mounted analyzer utilizes Zirconia Sensor Technology to give a more reliable measurement, faster response time and longer life compared to traditional analyzers. Incorporated into the PLC controls, our oxygen analyzer guarantees downstream purity levels are consistently achieved and maintained.
System Performance N/A The technologically advanced nano GEN2 nitrogen generator operates on the Pressure Swing Adsorption (PSA) principle to produce a continuous uninterrupted stream of nitrogen gas from clean dry compressed air.

Pairs of dual chamber extruded aluminum columns are filled with Carbon Molecular Sieve (CMS). Joined via an upper and lower manifold, the high density filled columns produce a dual bed system.

Compressed air enters through the inlet manifold (A) to the bottom of the 'online' bed and flows up through the CMS to separate the compressed air. The clean and dry air then flows up through the CMS stage (C) where oxygen and other trace gases are preferentially adsorbed allowing the nitrogen to pass through. The nitrogen then passes through the supporting bed layer (D) and outlet manifold (E) to the buffer vessel and a nano F1 buffer vessel filter before reentering the GEN2 nitrogen generator for purity monitoring.

After a preset time the control system automatically switches the beds. One bed is always online generating nitrogen while the other is being regenerated.

During regeneration, the oxygen that has been collected in the CMS stage and the moisture that has been collected in the optional integrated dryer stage are exhausted to atmosphere. A small portion of the outlet nitrogen gas is expanded into the bed to accelerate the regeneration process.
