Oxygen and Nitrogen Separation Plant

Home   /   Products   /   Oxygen and Nitrogen Separation Plant


Gases oxygen/gaseous nitrogen (GOX/GAN) plant is used for generating oxygen and nitrogen in the gaseous form. Gaseous oxygen produced in our plants has purity up to 99.7%, which is sufficient for medical and industrial applications. We use the latest technology in the manufacturing of air separation plants. We have technical collaboration with of ING. L. & Boschi since 1985 for exclusively using their cryogenic distillation process for manufacturing plant machinery for export throughout the world. We benchmark our quality standards with the best in the world.

Atmospheric air is let into air separation unit and is compressed in the air compressors. Molecular sieves designed and developed by Boschi are used for removing impurities from process air such as carbon dioxide, moisture and hydrocarbons. The air is cooled to cryogenic temperatures. The air is then moved into high pressure distillation columns where nitrogen is separated from oxygen and other gas & distilled further to achieve desired purity.  Leak-proof stainless steel columns are used. Latest pump technology is used to fill bone dry high oxygen/nitrogen in cylinders.

We have become the trusted GOX/GAN plant manufacturer in the world because our customers understand our commitment to make & supply the best plant machinery.  We use the quality materials in our fabricating and manufacturing. Our GOX/GAN plants are fully automated requiring only one semi-skilled operator to run it. It is equipped with digital color display panel that can shutdown the plant if nitrogen or oxygen purity falls below the specified limit. Our engineers and technicians are highly skilled in smooth implementation, erection and commissioning. Our customers trust our plant machinery of delivering solid performance during its entire life cycle.

MODEL RANGE —25 m3/hr to 10,000 m3/hr

With leak proof stainless steel column and skid mounted version for high purity medical and industrial uses. Our Gas Oxygen/Nitrogen Plants are used for filling high pressure Oxygen/nitrogen gas in cylinders/bottles by oxygen/nitrogen pump.


GAS OXYGEN: – Oxygen purity 99.7% at (150-160 Bar) for Oxygen cylinder filling & GAS NITROGEN: – High purity Nitrogen 99.99% (PPM optional) or cylinder filling.


The high pressure oxygen gas at 165-200 bar coming out from cold box (air separation column) at 99.7% purity will be filled directly in the oxygen cylinders in a oxygen cylinder filling manifold.


Q) Is it cost-effective to install GOX/GAN plant?

Installing GOX/GAN plant is beneficial in the long run compared to using nitrogen cylinders.  You will start to be in profit after two years.

Q) How much purity in nitrogen & oxygen is required for industrial & medical requirements?

Most of industrial & medical applications require oxygen purity up to 99.7%. Our nitrogen can plant can generate nitrogen with purity up to 99.9999%, which meets industrial & medical specifications.

Q) How long nitrogen plants last?

Our oxygen/nitrogen generators/ plants have a long life. Life cycle of our generators is over 25 years. Stay assured of a profitable investment that will yield profits for a long time.

Q) Can I get nitrogen & oxygen generator customized to my demand?

Yes, we can customize nitrogen & oxygen generators exactly as per your requirements of purity, capacity and pressure.

Q) What if oxygen/nitrogen generator does not produce nitrogen & oxygen with required purity?

Our nitrogen generators are equipped with digital display control panel that continuously monitors purity of oxygen. If purity falls below the required level, it shuts off the generator and sets off an alarm.
