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 19 standard models with capacity in the range from 2,4 - 1100 Nm³/hour from 95% to 99.999% purity. PSA generators Oxywise are designed for 24/7 operation. Each generator is equiped with automatic stop, enabling the generator to stop automatically when there is no consumption of gas from generator (i.e. product line is shut down).

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.
