NGM⁺ 7-70 nitrogen generator
The NGM⁺ is a compact, quiet, and reliable nitrogen generator that maximizes the robustness and simplicity of membrane technology. Thanks to its exceptionally low air and energy consumption, it also offers the lowest cost of ownership on today's market.
Reliable on-site nitrogen production with best-in-class performance
Membrane technology has traditionally provided high-quality, reliable on-site nitrogen production. Atlas Copco's new NGM⁺ 7-70 raises the bar with a significant additional benefit: lower energy costs. The high-efficiency generator comes with the lowest cost of ownership on today's market.
Technical advantages
Keep your costs low
Keep your costs low and achieve the lowest total cost of ownership in its class with the NGM⁺. It requires 20% less feed air than a conventional generator and eliminates the need for a wasteful feed air heater.
Reliable operations
NGM⁺ ensures a continuous supply of consistently pure, dry, high-quality nitrogen to keep your operations running smoothly. Soft start protects the membrane and extends its life.
Compact and quiet
Shutdown operation allows you to install the machine in your production area. No external tanks are required for constant-flow operations.
