Nitrgen and Oxygen Gas Generators

Atlas Copco offers not just compressed air and gas, but total solutions. On-site gas generators allow you to produce your own nitrogen and oxygen, requiring only a supply of dry compressed air. On-site gases can significantly reduce your costs compared to using bottles or bulk deliveries. 

Nitrogen is an important industrial gas for applications in chemicals, marine, electronics, food and beverage and packaging. Oxygen is vital in medical applications, waste water treatment, fish farming and ozone production. Our oxygen and nitrogen generators provide you with the flexible, reliable and cost-efficient solution your production needs. 

Atlas Copco supplies, installs and services your gas generators, along with your compressed air equipment. 

Atlas Copco PSA Nitrogen Generators:

Easy & cost-efficient nitrogen supply

Atlas Copco’s NGP and NGP+ series work with Pressure Swing Adsorption (PSA) technology, a reliable way to generate a continuous flow of nitrogen at a very high purity (up to 99.9999%).  The NGP nitrogen generator Both the NGP and NGP+ PSA nitrogen generators offer the same high and adjustable purity (from 95% to 99.999%) and the same plug-and-play installation. The NGP offers a lower investment cost, while the NGP+’s top-end energy-efficiency ensures the lowest cost of ownership. 

Both nitrogen generators are cost-efficient solutions when compared to bottles or bulk deliveries. Payback time depends on your nitrogen demand and local electricity cost, but quite often users notice a payback of less than a year. 

 

Benefits of NGP/NGP+: 

  • Plug-and-play installation. Your nitrogen generator only needs a supply of dry and clean compressed air.

  • Fully automated and monitored including oxygen sensor as standard.

  • Adjustable purity from 95% to 99.999%

  • Continuous availability

  • Low maintenance and service costs

  
Additionally, the NGP+ offers:

  • Premium energy efficiency: air-to-nitrogen ratio of 1.8 to 5.5.

  • Self-protective monitoring of the feed air quality: temperature, pressure and pressure dewpoint are constantly monitored. In the unlikely event of contamination, the feed air is automatically blown off.

  • Highest quality CMS (carbon molecular sieve): the adsorbent in the NGP+ has a high density and is compact spring-loaded with top/bottom equalization. A dedicated pressure sensor protects the CMS.

  

 

 

Applications for PSA nitrogen generators

With its high purity levels, PSA technology is preferred for applications such as: 

  • Metal processing and laser cutting

  • Pharmaceuticals

  • Electronics

  • Food and beverage processing and storage

 
Pressure Swing Adsorption working principle
PSA technology allows nitrogen molecules to be isolated from other molecules in compressed air (water, oxygen, CO2, etc). The carbon molecular sieve (CMS), the adsorbent in the generator, retains all those molecules and only lets the nitrogen pass through to the outlet. While the CMS in one vessel regenerates a second, connected vessel goes through the same adsorption cycle. These two connected vessels work together to ensure a near-continuous flow of nitrogen gas.
