Compressed Helium Gas & Liquid Helium


Helium is used by defense, nuclear and aerospace leaders for detecting leaks in critical equipment, including rocket engines, and for purging and propellant transfer. Our proprietary liquid helium pumping technology allows these industries to pressurize large on-site gaseous storage vessels at lower costs, with less energy and at faster rates.

Helium can also be used for purging. Since it has the lowest melting and boiling point of any gas, is inert, and has a low freezing temperature, it is used for purging by displacing very cold liquids such as liquid oxygen or liquid hydrogen safely without freezing.

Air Products has been a leading supplier of helium to the space industry since its inception delivering innovative approaches such as gas supply management systems which can reduce the cost of gas ownership and improve overall processes.

We offer a variety of technical services, gas-based solutions and a full line of industrial gases—helium, oxygen, nitrogen, hydrogen, argon and various gas blends for small and large volume users.  Talk to Air Products, our applications engineers can work with you to understand your operation and recommend improvements that can help you optimize gas use and improve product quality.
