Nitrogen generators with membrane technology

Benefit from our total package solution to meet your specific requirements. Thanks to Atlas Copco's global presence and worldwide service network, we are able to offer superior services. Our experts can help you to find the perfect configuration for your purpose built nitrogen system and complete it with portable air compressors and boosters.

Atlas Copco’s advanced technology allows you to easily generate nitrogen at air purity of your choice (up to 99 %), giving you the flexibility to align purity with your application needs. The integrated feed air filtration package ensures optimal performance, while the choice for lower nitrogen purity makes it possible to save on energy costs.

The NM series units are remarkable for their straightforward start-up and commissioning, making it easy to deploy a nitrogen system on site for any application.
The integrated feed air manifold connects various compressed air sources seamlessly, providing a hassle-free solution. Maintenance is a breeze, ensuring continuous operation with minimal downtime. And our global network is at your service to ensure optimal performance of your system.

You can count on Atlas Copco’s nitrogen membrane generators for a steady source of pure nitrogen. Our superior membrane technology sets us apart, resulting in low energy consumption. Using less energy per ton of nitrogen lowers your overall ownership costs to a minimum. Reliability is key for your application, and thus for our generator unit.

First, every nitrogen generator requires a compressor to supply the air from which the N₂ will be separated. A membrane nitrogen generator makes this separation happen with a membrane that consists of thousands of hollow polymer fibers. These fibers have a unique structure that allows only the oxygen and any remaining water vapors in the air to escape through its walls. This process is called permeation.
Water vapors will permeate very quickly; oxygen takes a little longer. Argon and nitrogen permeate rather slowly, meaning that they will remain in the fibers long after the water vapor and oxygen are gone.
Once outside the fibers, the O₂ and water vapor is vented out of the membrane housing and disposed of outside or in a safe area. This leaves the N₂ inside the hollow fibers, ready to be collected at the outlet. With the water vapors removed, the produced nitrogen is very dry, which is an additional benefit for many applications.

Our nitrogen membrane generators are suitable for every possible application where nitrogen is required. The more nitrogen is required for your specific application, the bigger unit you go for.
The nitrogen generators can cover multiple applications, including under-balanced drilling, pipeline purging and pigging, coiled tubing operations, reservoir pressure maintenance, and fracturing, amongst others.
It’s versatility also extends to mining applications – think extinguishing coal mine fires and inerting abandoned areas, and shipboard applications where the unit’s help to create inert atmospheres in vessels carrying crude oil, chemicals, LNG gas, and LPG gas. This wide range of applications highlights the generators’ adaptability across various industries.
