Reliable Gas Supply.
Built In, Not Brought In.
Our non-cryogenic air separation systems give you control over your oxygen and nitrogen supply. No liquid storage or frequent deliveries required.
Non-Cryogenic Technology
Our oxygen and nitrogen generators use VPSA and PSA processes to extract gas directly from ambient air. These systems separate gases without the need for cryogenic cooling, reducing energy use and equipment complexity.
Reliable Output
UIG systems are designed for consistent, clean gas generation. They’re engineered to meet your flow, purity, and pressure needs—ideal for industries where uptime and quality can’t be compromised.
Back-Up Ready
Want added reliability? UIG liquid systems provide a compact backup arrangement that triggers if gas production is interrupted.
Built for Your Operation
Every generator can be sized and configured to match your facility’s specific needs. UIG provides end-to-end engineering, installation, and support to ensure easy integration with your processes.
Generating Oxygen &
Nitrogen On-Demand
At UIG, we make generating oxygen and nitrogen onsite easy, so you can focus on running your operation, not managing your gas supply.

An inert gas used for cooling, blanketing, and pressurization.
On-Site Oxygen & Nitrogen
Purpose-Built for Your Industry
Whether supporting combustion in steel mills or providing inert atmospheres for chemical processing, our non-cryogenic generators deliver oxygen and nitrogen with the reliability industries count on.
Steel
Our onsite oxygen and nitrogen generators support steelmaking by providing continuous gas supply for combustion, cooling, and heat treatment applications, helping maintain process efficiency.
Energy
On-demand oxygen and nitrogen generation supports gasification, LNG production, and power generation with dependable gas supply and reduced logistics complexity.
Glass
Oxygen generated onsite enhances combustion control and energy efficiency in glass manufacturing, contributing to consistent product quality.
Chemicals
Non-cryogenic generators supply nitrogen and oxygen critical for chemical processing, enabling safer and more precise control of reactions and inerting processes.
Mining and Minerals
Onsite oxygen supports metal extraction and mineral processing, ensuring steady supply to critical operations while reducing reliance on external deliveries.
Metals
Our generators provide a continuous oxygen and nitrogen supply for refining, heat treatment, and other metal production processes requiring precise gas control.
Gas Supply, Your Way
UIG gives you the freedom to choose how you source your gas – whether you want a fully managed solution or complete control over your production. Our flexible approach ensures you get the reliability, efficiency, and cost structure that works best for you.
Non-Cryogenic Air Separation FAQs
What is non-cryogenic air separation?
Non-cryogenic air separation uses technologies like Vacuum Pressure Swing Adsorption (VPSA) or Pressure Swing Adsorption (PSA) to produce oxygen and nitrogen directly from ambient air without the need for ultra-low temperature cooling or liquefaction.
What purity levels of oxygen and nitrogen can be achieved with these generators?
UIG’s non-cryogenic generators typically produce oxygen with purity up to 93% and nitrogen with purity levels up to 99.999%, depending on the technology and application requirements.
What are the benefits of using onsite oxygen and nitrogen generators?
Onsite generation reduces dependency on bulk deliveries, lowers transportation and storage costs, improves supply reliability, and allows for flexible gas supply that matches your production needs.
How does onsite gas generation impact safety?
Onsite generation minimizes the risks associated with transporting and storing large volumes of cryogenic liquids, improving workplace safety and reducing handling hazards.
What is the typical footprint of a non-cryogenic oxygen or nitrogen generator?
Non-cryogenic generators are compact compared to cryogenic plants, making them suitable for facilities with limited space or where a smaller scale gas supply is needed.
Can non-cryogenic generators be scaled up as my gas demand increases?
Yes, these systems are modular and can be expanded or adjusted to meet growing or fluctuating gas demands, providing flexibility for changing operational needs.
What makes UIG different from other industrial gas suppliers?
UIG offers flexible supply options, from turnkey plants to DIY solutions, ensuring that you get a gas supply model that aligns with your business needs – not the supplier’s bottom line.
Where does UIG operate?
UIG, a wholly owned subsidiary of Nucor Corporation, designs, builds, and operates air separation plants across North America.
What services does UIG provide beyond non-cryogenic air separation?
UIG offers a full range of industrial gas services including cryogenic air separation, bulk liquid gas supply, gas consulting, pipeline gas delivery, maintenance, and support.
