NC-GEN: nitrogen supply for lower flow requirements

For processes with lower nitrogen demand, it is worth considering whether cylinder deliveries are the most suitable supply option or whether on-site generation would be a better fit. The choice depends mainly on the required flow, purity and pressure, as well as the space available for installation.

OMEGA AIR NC-GEN compact generators use Pressure Swing Adsorption (PSA) technology. The carbon molecular sieve selectively adsorbs oxygen and other air components, while nitrogen passes through as the product gas. Two adsorber vessels operate alternately to provide continuous production.

NC-GEN is suitable for smaller production lines, laboratories and selected industrial processes where high gas purity and a compact installation are important. Potential uses include laser cutting and food packaging, provided the generator capacity matches the process requirements.


Specification NC-GEN

Technology: PSA

Capacity: 0.43–6.5 Nm³/h

Nitrogen purity: Up to 99.999%

Operating pressure: Up to 8.5 bar

Capacity depends on the required purity and operating conditions.
