UIG designs and delivers nitrogen generation systems that provide a dependable, cost-effective supply for industries where performance and reliability can’t be compromised. Whether you need nitrogen for steelmaking, chemicals, energy production, or glass manufacturing, our plants are engineered to meet your exact flow, purity, and pressure requirements.
Partner with Nitrogen Generation Experts
Please provide your required nitrogen flow rates (average and peak), operating schedule (hours per day/week or 24/7), required delivery pressure, purity level, and units of measure.
Industrial Nitrogen Generation, Made Better
UIG nitrogen systems are engineered for precision. From separation to purification and storage, every stage is designed to deliver the purity, pressure, and reliability for your operational demands.
Nitrogen Generation
Nitrogen is produced on-site from compressed ambient air using cryogenic or noncryogenic solutions. These technologies isolate nitrogen by removing oxygen and other trace gases.

It’s gas the way you want it: Pure, transparent and predictable.
Gas You Can Work With™
The traditional approach to industrial gas is locking you into a rigid solution that prioritizes the supplier’s bottom line growth over yours. UIG is different. Discover a better way to work with industrial gas today.
Nitrogen Purification & Conditioning
Nitrogen is delivered at purity levels between 95% and 99.999% to match application needs.
Nitrogen Storage
Nitrogen can be stored in cryogenic tanks for backup purposes as well as in buffer tanks for peak usage.
Nitrogen Generation.
Purpose-Built for Industrial Needs.
Steel
Nitrogen is used to create inert atmospheres during annealing and heat treatment, preventing oxidation and maintaining product quality.
Energy
Nitrogen is essential for pipeline purging, turbine cooling, and explosion prevention for safe energy operations.
Glass
In glass production, nitrogen helps maintain furnace stability and reduces oxidation, resulting in higher-quality glass products.
Chemicals
Nitrogen is used in inerting and blanketing processes to minimize the risk of combustion and contamination during chemical manufacturing.
Mining and Minerals
Nitrogen displaces oxygen in confined spaces, enhancing underground safety and reducing the risk of fires or explosions.
Metals
In metal manufacturing, nitrogen is used in welding and heat treatment to shield materials from oxidation and ensure cleaner results.
Manufacturing & Construction
Nitrogen’s dry, non-reactive properties are crucial for laser cutting, additive manufacturing, and pressure testing applications.
Food & Beverage
By removing oxygen from packaging and production environments, nitrogen helps extend shelf life and preserve freshness.
Healthcare
Nitrogen supports cryopreservation, sterile packaging, and precise equipment calibration in critical medical applications.
