Portable Nitrogen Generator

CKG is known for standard, economically priced nitrogen generation systems that can be customized as needed. On Site Gas manufactures nitrogen container systems for highly efficient, cost-effective nitrogen gas generation.

Available to be Used for Onshore and Offshore Applications

Data Sheet:


General Details

We design and build our nitrogen generator container systems to fit a steel ISO container or similar structure for ease and security of shipment. On Site Gas designs and builds the entire nitrogen generator in a 10-, 20- or 40-foot container that can be transported on a truck. When the nitrogen container unit reaches the end-user’s facility, all that’s required is the electrical hookup to begin generating nitrogen on site

Advantage of Nitrogen Container Systems
  • Nitrogen membrane or PSA generators

  • Flows up to 90,000 SCFH and purity as high as 99.9995%

  • Can be deployed for remote or stationary applications
  • Maintenance-free operation
  • Low overhead

  • Rapid return on investment
How It Works

CGT PSA Nitrogen Generators operate on the Pressure Swing Adsorption (PSA) principle to produce a continuous stream of nitrogen gas from compressed air. Two towers are filled with carbon molecular sieve (CMS). Pretreated compressed air enters the bottom of the on-line tower and follows up through the CMS. Oxygen and other trace gasses are preferentially adsorbed by the CMS, allowing nitrogen to pass through. After a pre-set time, the on-line tower automatically switches to regenerative mode, venting contaminants from the CMS. Carbon molecular sieve differs from ordinary activated carbons in that it has a much narrower range of pore openings. This allows small molecules such as oxygen to penetrate the pores and be separated from nitrogen molecules which are too large to enter the CMS. The larger molecules of nitrogen by-pass the CMS and emerge as the product gas
