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.
The Technology
Nitrogen Generator consist of two columns filled with carbon molecular sieve (CMS). Pre-treated compressed air enters the active column and follows up through the CMS. Oxygen and the other gases are being adsorbed while the nitrogen passes through. The active column is pressurized. When pressure is released, column becomes inactive and completely regenerate. In order to secure steady flow nitrogen generator is built from two columns; one is active while the other is inactive. At the end of cycle they switch roles.
