NITROGEN GENERATOR ATLAS NGMs2
Whether your company is specialized in chemical manufacturing, electronics, laser cutting or food and beverage, a dependable supply of industrial gas is crucial. Compared to the on-demand delivery of gas bottles or tanks, on-site production of gas offers a wealth of advantages ranging from cost savings to continuous availability. Atlas ’s advanced nitrogen and oxygen generators offer you the ultimate solution: flexible on-site production of industrial gas at the lowest possible cost.
Atlas ’s latest membrane and PSA generators extend the advantages of the current range. Total lifecycle cost consists of the initial investment cost of the on-site installation, the service cost, and the energy cost. The NGP/NGM range has the lowest investment cost. However, with increasing running time, you are better advised to switch to the NGP + /NGM + range to reduce energy costs.
With an air factor* of 1.8 (at 95%) to 5.5 (at 99.999%) and a special cycle time modulation algorithm, the running cost of the new NGP + can be reduced by 50%, compared to other N 2 generators.
Wide Range of Applications
• Food & beverage (storage & packaging). • Pharmaceutical applications.
• Plastic injection molding. • Electronics.
• Laser cutting. • Semiconductor manufacturing.
• Chemical applications. • Metal heat treatment.
• Cable & optical fiber industries. • Glass industries.
• Fire prevention. • Aquaculture.

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.
