Nitrogen Generators

NOXERIOR offers a wide range of nitrogen generators for all kinds of applications and any flow demands.

NOXERIOR from NOVAIR Groupe is the only manufacturer worldwide to offer an expertise in all on-site nitrogen production technologies. With Modular, PSA and Membrane systems, we provide the best possible solution for each nitrogen generation requirement.

Unlike all traditional supply methods (ie cylinders of bulk nitrogen recurrent deliveries), on-site nitrogen production offers many advantages to end users : production on-demand, more safety, no logistics constraints, eco friendly solution, constant control over nitrogen purity, etc…

1. Modular PSA : the most flexible on-site nitrogen production

NITROSWING® modular PSA generators implement a unique Pressure Swing Adsorption technology. Unlike twin-tower standard systems, NITROSWING®  modular generators feature multiple modules of molecular sieve, each implementing an optimized patented PSA process.

New standards are set by this unique and patented product  combining flexibility, quality and efficiency of PSA Nitrogen Generators.

2. Twin-Tower PSA : for larger nitrogen consumption requirements

The NITROPLUS ECO LINE® twin tower generators extract the available nitrogen in the ambient air from the other gases by applying the Pressure Swing Adsorption (PSA) technology. During the PSA process compressed, cleaned ambient air is led to a molecular sieve bed, which allows the nitrogen to pass through as a product gas, but adsorbs other gases.

Built to last for years of trouble-free continuous heavy-duty operation at low operational costs, the twin tower PSA technology offers the largest production capacities.

3. Membrane nitrogen generators

Noxerior offers a choice of nitrogen generators implementing the membrane technology.  Based on a continuous process implementing a selective permeation across the membrane wall, this technology is particularly appropriate for middle purity requirements. NOXERIOR incorporates the membrane technology in specific solutions designed for EPC projects. It is also intergrated in a dedicated nitrogen generator for the marine application, combining guaranteed stable puity and ultra fast response time.

4.Special Products

Noxerior offers custom-engineered nitrogen packages for each application NITROSWING LASERPACK, on-site nitrogen supply for the laser-cutting industry is one of them.


A large scope of supply

Noxerior from Groupe Novair offers the full nitrogen production line, including feed air unit (compressed dry air and air receiver), nitrogen generator and nitrogen receiver & high pressure cylinder filling (optionally).

The company is also expert in the design of turn-key installations of either on a single skid or inside an ISO freight container.

Outstanding Features

The towers of PSA systems are intrinsically subject to considerable pressure cycles every 60 to 90 seconds.
Safety is fundamental for NOXERIOR. This is why we guarantee, product safety of all PSA Nitrogen Generators with a fatigue analysis for cyclic load of the PSA module / tower design and certify it to PED 97/23/CE (Cat. 1 – Module H) or ASME Sec. VIII, Div. 2.

Energy costs through the supply of compressed air are the largest part of the operational costs of NOXERIOR Nitrogen generator. With an optimised PSA process, we dedicate high attention to energy efficiency and produce the most efficient nitrogen generators currently available.

All NOXERIOR Nitrogen Generators are sized to the most difficult local ambient conditions at the installation site. This guarantees the supply of the nitrogen quantity requested by the customer even under extreme operating conditions.
