PSA nitrogen and oxygen generators
(NGP, NGP+, OGP)

Atlas ’s NGP, NGP+ and OGP nitrogen and oxygen generators are easy to install and use.They offer the required purity with a high flow capacity, making them suitable for a range of applications.

High flow capacity
The wide product range and gas flows exceeding 3,000 Nm³/h
(NGP/NGP+) make these generators ideal for a variety of demanding applications.

Ready to use
• Only requires a supply of dry compressed air.

• Plug-and-play.
• No specialist installation or commissioning.

• Fully automated and monitored including oxygen sensor as standard.
• Service-friendly.

Desired purity
• NGP/NGP+: nitrogen concentrations from 95% to 99.999%.
• OGP: oxygen concentrations from 90% to 95%.

Exceptional reliability
• Robust design.
• Continuous availability (24 hours a day, 7 days a week).
• Potential risk of production breakdown due to gas running out is eliminated.

Cost savings
• Low operating expenses.
• No additional costs such as order processing,refills and delivery charges.
• Limited maintenance costs.

Membrane: Compact all-in-one N 2 supply
Atlas NGM/NGM + /NGMs nitrogen generators utilize proprietary membrane separation technology. The membrane separates compressed air into two streams: one is 95-99.9% pure nitrogen, and the other is oxygen enriched with carbon dioxide and other gases.

Instant supply of nitrogen between 95% and 99.9%
The generator separates air into component gases by passing inexpensive compressed air through semi-permeable membranes consisting of bundles of individual hollow fibers. Each fiber has a perfectly circular cross-section and a uniform bore through its center. Because the fibers are so small, a large amount of fibers can be packed into a limited space, providing an extremely large membrane surface area that can produce a relatively high volume product stream.
