PRODUCT Industrial Nitrogen Generation

Industrial Nitrogen Generators

On site nitrogen generation is the most economic and one of the most reliable forms of nitrogen gas delivery available.  First and foremost, on site nitrogen generation offers you huge savings compared to traditional gas supplies with gas costing as little as 3c per cubic meter.  Generation will also deliver you the ultimate in convenience – a never ending supply of gas at the purity, pressure and flow you require, on site, on demand.

Also, simply by switching to a nitrogen gas generator, you eliminate your risk of running out of gas, cut your exposure to gas price increases and free yourself from lock in gas contracts.

On Site Gas Systems nitrogen generators are available in a wide range of purities and flow rates to match almost any application and with each system custom built to your specific requirements, we guarantee to deliver the correct flow, purity and pressure as specified by you.

Nitrogen generators are available at purities ranging from 95% through to 99.9995% with every step in between.  It is important to know that nitrogen purity with PSA (pressure swing adsorption) technology will not naturally degrade over time so you can assured of consistent gas quality for the life of the system.

On Site Gas Systems commercial division is typically focused around PSA technology however we do offer membrane technology when the application calls for it.


General nitrogen generator system capabilities:

Purity: 95% – 99.9995%

Flow: <1m3/hr – 2000m3/hr from a single system

Low pressure: up to 9 bar

High pressure: up to 350 bar

All systems come as standard with an integrated touch screen for system operation and monitoring. The touch screen provides general operating controls, alarms and maintenance messages as well as an integrated oxygen analyser for real time purity monitoring down to PPM level if required.

Controls as standard operate the nitrogen generator only however On Site Gas Systems have the capability to also control compressors to enable simplified operation as a complete system.

Systems can be programmed and configured for remote monitoring and control if required and complete integration into plant DCS.

Australia’s Leaders in Nitrogen Generators for Every Application

On Site Gas Systems have a range of products suited for use across hundreds of applications and for business of all sizes. The nitrogen generators we have for sale are custom built for each application to meet the user’s exact purity, pressure and flow requirements. Follow your industry category above to learn more about how the systems can help you and your application.

On site technology for your application

On site nitrogen generation by way of non-cryogenic air separation can be achieved using two methods – PSA generation and membrane generation.

The systems we have for sale offer both air separation technologies so you can be sure you will get best recommendation for your application.

  • Membrane
    • With almost no moving parts, membrane based models are an ultra-reliable means to produce the gas on site. These systems are particularly well suited to applications that require less than 98% purity, portability, or both.

  • PSA (pressure swing adsorption)
    • PSA systems are well suited for applications where it is expected to be in a fixed location or purity requirements are high. PSA technology can reliably generate nitrogen up to 99.9995% and are more efficient at higher purities than membranes are.

Typical industrial applications requiring on site nitrogen

  • Oil, gas and coal
  • Chemical
  • Medical
  • Tank inerting
  • Electronics manufacturing
  • Laser cutting
  • Laboratory
  • Food processing and packaging
  • Coffee
  • Wineries
  • Heat treating

And many more.

Benefits of on site generators

Having a system on site offers a reliable, on-demand stream to your process while offering significant cost savings and fast return on investment. It is the most cost effective means of gas supply available - it can be generated for as low as 3c per m3 – that can be up to a 90% cost saving compared to out-sourced supplies.
