Nitrogen Generator

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.
