Membrane Nitrogen Generator NGMs2

The NGMs2 membrane nitrogen generator produces gas from compressed air. The device replaces cylinders and cryogenic supplies with a continuous source of nitrogen. It is suitable for tyre inflation, food packaging and inerting in the oil & gas and plastics industries. The membrane design ensures a stable gas supply across a wide range of operating conditions.

• Membrane technology: one or several high-performance membranes work together, ensuring maximum nitrogen output from a minimum volume of compressed air.
• Wide purity range: from 95% to 99.9% allows precise matching to the requirements of a specific process without overpaying for excess gas quality.
• Dual pre-filtration: a 2-stage premium filtration system maintains air class 1:-:1 per ISO8573-1:2010 and protects the membrane from contamination.
• Long service life: the design is built for continuous operation of over 15 years, even with unstable compressor starts and stops.

Operating principle of membrane technology

The generator produces nitrogen directly from compressed air using membrane gas separation. Polymer membrane fibres allow oxygen and moisture to pass through faster than nitrogen, leaving a nitrogen-enriched stream at the outlet. Purity is adjustable within a range of 95% to 99.9%, corresponding to a residual oxygen content of 5% to 0.1%. This principle eliminates the need for cylinders or cryogenic gas supplies to support ongoing production.

Modular design of the membrane unit

The working unit of the NGMs2 membrane nitrogen generator consists of one or several high-performance membranes. They are connected to achieve the rated inlet air flow. This arrangement ensures maximum compressed nitrogen output with minimum compressed air consumption. The design maintains stable performance across a wide range of operating conditions, simplifying integration into various production lines.

Pre-filtration system and service life

For stable long-term operation, the generator is equipped with a 2-stage premium pre-filtration system. It ensures inlet air quality of class 1:-:1 per ISO8573-1:2010. This eliminates the risk of membrane damage due to poor compressed air quality, failed starts, or unplanned stops. Thanks to this protection, the equipment is designed for continuous operation of over 15 years.

Applications

The NGMs2 membrane nitrogen generator adapts to industry requirements thanks to adjustable gas purity from 95% to 99.9%.

• Oil & gas industry: Inerting of tanks and pipelines with nitrogen of up to 99.9% purity reduces the risk of oxidation and ignition during technological operations.
• Food packaging: Displacing oxygen with nitrogen slows down product oxidation and extends shelf life without using bottled gas.
• General inert atmosphere (blanketing)A stable nitrogen supply from the membrane unit maintains a protective atmosphere for oxygen-sensitive materials and substances.
• Plastics industry: Nitrogen used during extrusion and injection moulding prevents oxidation of the polymer melt, preserving product properties.
• Tyre inflation: Adjustable gas purity provides more stable tyre pressure due to a reduced oxygen content compared with compressed air.
• Other industrial applications: The modular number of membranes allows the generator's output to be matched to non-standard production processes requiring nitrogen on demand.
