Nitrogen generators

Nitrogen generators produce nitrogen gas from compressed air and offer a cost-effective, reliable and safe alternative to traditional nitrogen gas supplies such as cylinder or liquid.

Nitrogen generators are available in 20 standard models with capacity in the range from 1 - 1800 Nm3/hour from 95% to 99.9995% purity. Oxywise PSA generators are designed for 24/7 operation. The touchscreen control has user friendly interface with automatic start/stop function based on gas consumption.

PSA Technology

A PSA Nitrogen Generator consists of two columns filled with a carbon molecular sieve (CMS). Pre-treated compressed air enters the active column and flows up through the CMS. Oxygen and other unwanted gases are adsorbed while the nitrogen passes through. The active column then becomes fully pressurized. When this pressure is released, the column becomes inactive and completely regenerates during the depressurization. In order to secure a steady flow of nitrogen each generator is built from two columns; one is active while the other is inactive. At the end of each column’s cycle, they switch roles.

    The start up procedure varies according to what type of system you have - generator only, stand alone, skid mounted or containerised. However, the start up procedure is very easy to follow and full instructions are included in the operating manual that comes with your system. If you encounter any problems, our service team are always available to provide support.
    Return of investment (ROI) is calculated as 1-2 years. Local parameters have to be considered and my shorten or prolong the stated period. If you wish to receive a ROI for your project, please contact us on
    Time of installation depends on a complexity of the supply. It can take from 2 days to a week.
    The start-up also includes a basic training of the operators on site.
    To increase your capacity you can use either a large generator or to add another oxygen generating line. Please contact us on for more details.
