Onsite gas generation tailored to your needs

How does a nitrogen generator work?

To produce your own nitrogen, all you need is a compressor and a nitrogen generator. That’s because air consists of 78% nitrogen and 21% oxygen. When you feed compressed air into a nitrogen generator, it separates the N2 from the O2. There are two main technologies to produce nitrogen:

PSA technology
Utilizing PSA technology, Pressure Swing Adsorption (PSA) effectively isolates nitrogen from compressed air by utilizing adsorbent materials. By passing the air through a vessel containing Carbon Molecular Sieves (CMS), the oxygen is captured, allowing only nitrogen of up to 99.999% purity to exit. PSA generators are well-suited for applications requiring high-flow and high-purity nitrogen.

Membrane technology
Membrane technology is a very simple, reliable and continuous N2 production method. Compressed air is pushed through hollow polymer membranes. The oxygen in the air escapes through the fiber walls and permeates into the atmosphere. This leaves quality nitrogen with a purity between 95% and 99.5% at the generator outlet.

Membrane Nitrogen Gas Generators

Pneumatech’s PMNG range of nitrogen generators utilizes proprietary membrane separation technology. Membrane generators are an excellent choice in low (90%) to medium (99,5%) purity applications such as tire inflation, fire prevention, tank blanketing and pipeline drying. Nitrogen pressures can go up to 12 bar (g) without the need for an additional booster.

Engineered for simplicity, durability and ease of use make the PMNG what we believe to be the most user friendly unit in the market. All pre-filters and controls are included inside the canopy.

PSA Nitrogen Gas Generators

The PPNG series is Pneumatech’s premium on-site nitrogen solution for low to high flows, with best-in-class performance and the most complete scope of supply.

The generator has outstanding air factors at full load thanks to the use of highly efficient Carbon Molecular Sieves (CMS) and back-flow pressurization.
The air consumption is also optimized at reduced nitrogen flow or pressure demands, thanks to the advanced energy saving algorithm, which automatically adjusts the cycle times of the generator.
The control and monitoring capabilities of the PPNG series are truly impressive.

High Pressure Nitrogen Skids

Discover the comprehensive capabilities of Pneumatech's PPNG NE nitrogen skid—an integrated solution offering a variable speed drive (VSD) compressor, high-pressure booster, top-tier PSA nitrogen generator, and complete storage and treatment features. Revolutionize your in-house production with this all-encompassing system, freeing you from gas procurement and delivery hassles.

What is a nitrogen generator?

A nitrogen generator is a machine that separates nitrogen from compressed air, which consists of 78% N2 and 21% O2. A gas generator is the easiest, most flexible, cost-efficient and sustainable way of obtaining your own nitrogen supply.

The benefits of on-site nitrogen generation

On-site generation offers convincing benefits compared to liquid or gaseous N2 deliveries.

1. Cost efficiency
Producing your own nitrogen with the purity you need allows you to significantly reduce your cost of gas

2. Sustainability
Eliminate the transport emissions that nitrogen deliveries generate. In addition, Pneumatech’s on-site generation solutions are super efficient, minimizing your energy use and your environmental footprint.

3. A reliable nitrogen supply
No need to count on external vendors. On-site generation gives you complete control over your nitrogen supply.

4. No logistics
Say goodbye to always monitoring your N2 supply, working with vendors, and tracking and handling deliveries. 

The use of nitrogen is required in countless industrial and professional applications
