Whether you’re installing a brand-new cryogenic air separation plant, relocating an existing system, or upgrading for efficiency and reliability, UIG has the end-to-end engineering and technical support to bring your project to life—on time, on budget, and on your terms.


Designed & built for you. Backed by engineers.

We’re not just gas suppliers—we’re your design, operations, and maintenance partner. Because we operate our own plants, we approach your facility like it’s our. That means smarter design decisions, more practical installations, and better long-term performance.

On-Site Oxygen, Nitrogen & Argon Supply

Our core business is the supply of oxygen, nitrogen, and argon from UIG-designed plants built adjacent to your operation. The onsite model is typically the most economical means of oxygen and nitrogen supply for customers consuming 100-200 tons per day or greater of product, subject to physical location.

State-of-the-Art Industrial Gas Systems

We design and manufacture complete cryogenic air separation systems customized to suit your unique operational needs. Our plants are designed to produce gases in both liquid and gaseous forms, offering flexibility for different industrial applications.

Relocated Plants

As an alternative to all-new plant offerings, we also partner with customers to identify used assets that may fit your process needs. We have the expertise and experience to lead the reliable, efficient refurbishment of them.

Flexible Supply Arrangements

We recognize the value of flexibility to both growing and established companies. We focus on defining your gas supply needs first, then present the ownership and leasing options available. The end result is giving you a choice and input into your gas supply.

Liquid Storage & Vaporization

We design and install cryogenic liquid storage systems for delivery of gas products to your use point. Our engineers can customize systems to fit your consumption and reliability needs while our robust, global supply chain allows UIG to deliver systems on time and on budget.

Consulting Services

While we would love to provide you with the gas supply your company needs, we understand that the nature of gas supply contracts don’t always put you in a position to act on that immediately. UIG is happy to provide consulting services to help answer any questions you have about your current or future gas supply.
