Reliable and efficient technology
PSA reliable and proven
Based on Pressure Swing Adsorption (PSA) technology, Atlas Copco’s NGP/NGP+ nitrogen generators provide a continuous flow of
nitrogen at desired purity.
High purity nitrogen supply up to 99.999%
Atlas Copco’s 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.
Variable cycle saver
Most users don’t utilize the maximum capacity of their nitrogen generator all the time.
Our in-house developed Variable Cycle Saver (VCS) eliminates energy waste during lower demand and in colder temperatures, giving you up to 40% additional energy savings.
1. Low load
2. Full load
3. Seasonal efficiency
1. Low load: When there is less demand for nitrogen, VCS optimizes the PSA cycle to reduce the generator capacity and thus the feed air consumption to what is needed to generate the lower volume.
2. Full load: The generator is sized for reliable production at full load in hot temperatures (if applicable). In these conditions, VCS is not needed.
3. Seasonal efficiency: At full load in cold conditions, a nitrogen generator works more efficiently, increasing its capacity. Here, the VCS of the NGP⁺ will also kick in to reduce feed air and energy costs.
