Oxywise offers the ideal solution with a comprehensive range of cost-effective compressed air nitrogen generation systems, enabling users to produce their entire nitrogen gas demand on-site and under their control.

Compared to traditional supply methods, an on-site nitrogen generator is extremely cost-effective with a short payback time – in many cases less than twelve months.

What is a nitrogen generator and how does it work?

The air we breathe is approximately 78% nitrogen and 21% oxygen, with small amounts of other gases such as neon and hydrogen making up the remaining 1%. A nitrogen generator is able to produce a continuous uninterrupted flow of nitrogen gas from clean, dry compressed air. It uses a carbon molecular sieve (CMS) where oxygen and other trace gases are preferentially adsorbed and nitrogen is allowed to pass through.

Dual Chamber System

Extruded aluminum columns are filled with carbon molecular sieve (CMS). Connected via an upper and lower header, the high-density filled columns create a dual system. After a preset time, the control system automatically switches columns. One column is always in operation and generates nitrogen while the other is being regenerated. During regeneration, the oxygen collected in the CMS stage and the moisture collected in an optional integrated dryer stage are exhausted to the atmosphere. A small portion of the nitrogen outlet gas is expanded into the trough to accelerate the regeneration process.

Nitrogen is used for a wide range of industrial applications, including atmospheric packaging of perishable food products. It is also used to prevent fires and explosions in chemical plants. Using high quality compressed air to supply the generators ensures long and trouble-free service and guarantees optimum performance.

Oxywise has a comprehensive range of systems that include everything needed to set up an on-site nitrogen production system. CompAir air compressors and pre-treatment packages include desiccant dryers and coupling filters to ensure the highest quality air supply to the generators. The gas can be produced from your existing system with minimal additional space.

Common methods of supplying gas include high pressure cylinders, mini tanks or storage vessels. The Oxywise generator makes the workplace significantly safer for employees, eliminating the safety risks associated with traditional methods. Compared to outsourced supplies, on-site nitrogen production offers greater flexibility and has a significant impact on time and cost.
