Aerospace & Aircraft

Our liquid oxygen has prepared and launched many bipropellant vehicles since the early 1960’s. We also supply gaseous oxygen to support rocket fuel combustion.

Automotive & Transportation Equipment

Oxygen is used as a plasma cutting gas, an assist gas for laser cutting, and is sometimes added in small quantities to shielding gases.


In its purest form, oxygen is used in many important chemicals such as ethylene oxide and titanium dioxide. It is also used to increase the production capacity of oxidation processes.


Using oxygen in the place of air can increase performance and capital efficiency in many industries and can enable carbon capture processes. It is often used in boilers and process heaters, industrial fermenters and gasification processes to improve productivity.


We are a long time provider of USP grade oxygen and bulk oxygen storage equipment to medical facilities, frequently used to aid in the treatment and prevention of hypoxemia and hypoxia.

Metal Production

As an industrial gas, oxygen is used to replace or enrich air, ultimately increasing combustion efficiency in both ferrous and non-ferrous metal production.

Pharmaceutical & Biotechnology

Critical for cell growth applications, oxygen is used in fermenters and bioreactors.


Oxygen is widely used in refineries to increase the capacity of Fluid Catalytic Cracking (FCC) plants and Sulfur Recovery Units (SRU), and to improve wastewater treatment operations.

Water & Wastewater Treatment

Used as an industrial gas, oxygen can supplement or even replace air in the aeration basin to maximize treatment capacity, minimize VOC emissions, reduce odor and foam, and increase flexibility. It is also used as a feed gas to generate ozone for water disinfection.

Welding & Metal Fabrication

Oxygen is used as a plasma cutting gas, an assist gas for laser cutting, and is sometimes added in small quantities to shielding gases.

Cylinders & Liquid Containers

For smaller, more specialized applications, we offer oxygen in high-pressure gas cylinders and liquid oxygen dewars in a variety of sizes.

Bulk & Microbulk Delivery

Our bulk liquid and gas delivery systems offer a full range of purities and oxygen tank sizes, for your oxygen supply needs.


Our pipeline supply systems offer flexibility and economy for customers who consume very large volumes of oxygen gas each day.

On-Site Production

Our cryogenic air separation plants produce thousands of tons of high purity oxygen efficiently and safely every day so we can deliver an uninterrupted supply of oxygen gas to our customers. For lower purity applications, our non-cryogenic plants can produce a range of purities from 90% and higher in wide range of volume capacities.

Small On-Site Production

Our small on-site VPSA plants, which provide from 30-200 MTPD and up to 93% purity, are available for those who want the efficiency and reliability of on-site oxygen, but in smaller amounts than a larger on-site production plant.
