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.
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.
