PSA: Reliable and proven
Ultra-High Purity Nitrogen from PSA Technology
For industries requiring the highest levels of nitrogen purity, Atlas Copco’s PSA (Pressure Swing Adsorption) generators provide a smart, scalable solution. These generators can achieve nitrogen purity up to 99.999%, ideal for pharmaceutical, electronics, metal fabrication, and food-grade applications.
How PSA works:
PSA systems separate nitrogen from compressed air using carbon molecular sieves. Oxygen, water vapour, and other trace gases are adsorbed by the sieve material, allowing nearly pure nitrogen to pass through for use in your processes.
Features of Atlas Copco’s PSA nitrogen generators:
-
Purity options from 95% to 99.999%
-
High flow capacity – up to 3,000 Nm³/h
-
Energy-saving design with cycle time modulation
-
Advanced Elektronikon® control and SMARTLINK remote monitoring
-
Optional nitrogen skids for high-pressure applications (ideal for laser cutting)
NGP and NGP+ Series:
-
NGP: Offers low initial investment, ideal for moderate usage.
-
NGP+: Optimised for energy efficiency, offering up to 50% lower running costs through improved air-to-nitrogen ratios (as low as 1.8).
Applications:
-
Laser cutting
-
Electronics and PCB manufacturing
-
Pharmaceuticals and chemicals
-
Food packaging under modified atmosphere
-
Metal processing and heat treatment
Designed for 24/7 reliability, PSA nitrogen generators eliminate gas delivery bottlenecks while offering significant long-term savings.

High purity nitrogen supply up to 99.999%
NGP/NGP+ nitrogen generators use Pressure Swing Adsorption technology to isolate nitrogen molecules from other molecules in compressed air. Oxygen, CO2, water vapor and other gases are adsorbed. The result is virtually pure nitrogen at the outlet of the generator. The NGP/NGP+ Series is a very cost-efficient source of nitrogen used in various industries like food and beverage, metal processing, electronics, and many others.
