On-site Cryogenic Nitrogen Generation


Fixed or flexible—get the right welding and cutting solutions.

The best way to meet high nitrogen demand is with a solution tailored to your unique needs. That’s why we provide custom-engineered solutions for a more cost-effective and eco-friendly alternative to bulk-delivered nitrogen.

Reduce consumption and increase efficiency with an on-site nitrogen generation system from Airgas. We help develop your seamless product supply and on-site system installation with a comprehensive offering:

  • Engineering, design and construction
  • Start-up and commissioning
  • Ownership, operation and maintenance
  • Back-up supply systems

Generate Savings

Generating your own nitrogen on site can be extremely cost effective—as long as you make smart choices. We’ll help you choose a system that suits your needs and helps you realize savings in the process. We’ll determine what’s right for you based on a variety of factors:

  • Flow rate
  • Pressure
  • Flow consistency
  • Power cost
  • Purity
  • Utilization

Using only the highest-quality components, Airgas on-site systems are engineered for superior performance and high levels of automation. As your system operates unattended, you can trust our field technicians to monitor operations remotely and perform preventative maintenance.


Generate Sustainability

Located onsite, our nitrogen generation systems can help you save more than just money by helping reduce your carbon footprint by as much as 70 percent. The system generates gaseous instead of liquid nitrogen, which requires much less power and, since gas is generated onsite, there’s no bulk liquid transport—eliminating the use of diesel fuel.


System Features & Options

Airgas on-site nitrogen plants cover a full product offering of membrane, PSA and cryogenic systems. Additionally, systems can be provided as a stand-alone on-site facility, a pipeline project or in combination with a merchant air separation unit (ASU).

Features include:

  • Modular layouts
  • Durable, weather-resistant designs
  • Remote monitoring and control
  • Load tracking to nitrogen demand


Nobody understands the needs of your operation better than Airgas. Produce your own nitrogen—and your own success—with a cost-saving on-site generation system.
