Nitrogen Gas Generator Product Line Side by Side

GDN2 Nitrogen Generators

In many applications, oxygen is the enemy. Oxygen can cause food to spoil, rubber to deteriorate and steel to rust. The best way to combat the negative effects of oxygen is to supplant it with nitrogen. After all, the air around you is 78% nitrogen.  For many years, the only option was to purchase bottled nitrogen. With the introduction of on-site nitrogen generators, users were able to cut the cord and move away from billion-dollar bottled nitrogen suppliers. This will typically lead to a huge financial savings that often results in an ROI of 18 months or less.

GDN2 Nitrogen Gas Generators

On-site nitrogen generation

The perfect fit to maximise productivity

Using high quality compressed air to supply the nitrogen generators, ensures long and trouble-free service and guarantees optimum performance. Gardner Denver compressors and pre-treatment packages including dryers and filters guarantee the highest quality air supply for nitrogen generation. Nitrogen gas can even be produced from spare capacity in your existing compressed air system with a minimum of additional floor space.

Lowest total lifetime cost

With unique design and advanced Energy Saving Technology at its core, our market leading on-site generator requires less compressed air to generate more nitrogen than other solutions. This translates into reduced energy consumption. Coupled with Substantially lower servicing costs, reduced Downtime and a longer working life, it adds up to the most cost-efficient nitrogen supply available; Significantly more affordable than traditional sources, and delivering huge savings over the lifetime of the generator.


Highest efficiency, highest output nitrogen gas generator

Using less compressed air, Gardner Denver generators produce nitrogen at the lowest unit cost. Through extensive research and design, flow modelling technology, materials and controls system, Gardner Denver can provide the highest efficiency nitrogen generator.

Carbon Molecular Sieve (CMS)

Utilising the most robust, highest efficiency CMS - is one of the main reasons behind the major performance benefits such as more gas for less compressed air, reduced energy consumption; a very long working life and a more compact unit.

"Industry compliance, food and pharmaceutical safe"

Produces pharmaceutical and food grade nitrogen gas in accordance with European statute. Manufactured from materials that are safe for gas contact with pharmaceutical and food products, in line with the USA Food & Drugs Administration Article 21 (FDA Article 21).

Unique Energy Saving Technology (EST)

Dramatically reduces compressed air consumption and energy cost, by ensuring that the inlet compressed air flow is always exactly matched to the nitrogen gas outlet flow and purity.


You can be specified your system for your current requirement, and simply enlarge with additional generators - as and when demand increases. And with 100% back up provided by a single extra generator, there are extra savings on duplicating the complete set up.

Remote monitoring

With 'MODBUS', single or multiple generators can be connected to proprietary remote management and generator control systems.
