Expert solutions to help you succeed

Air Products offers a full range of nitrogen, argon, and helium supply options and technical services for small and large volume users. Our applications engineers can work with you to understand your purging process and recommend improvements that can help you optimize gas use and improve product quality.

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

Air Products can help optimize your nitrogen, argon, or helium supply modes based on your requirements. To help determine if liquid or on-site generation better suits your needs, we consider factors such as your usage pattern, flowrate, pressure and purity.

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.

With the commercialization of the space launch industry, opportunities to advance in space technology have grown exponentially. With this expanding market comes an increased need for industrial gas to reliably and safely propel rockets and space craft, treat metal and composite components for their extreme environment, and ensure safe, reliable operation and storage of cargo and crew. Having served the space industry since its inception, Air Products has the practical experience and technical expertise to help you venture into the unknown.

“How can I optimize my helium usage?”
Helium gas plays a vital role in the production of rocket components and supporting launch activities. Defense, nuclear, and aerospace manufacturers use helium for detecting leaks in critical equipment such as rocket engines, and for purging and propellant transfer. Many face the challenge to increase quality while reducing costs. 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. 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. Air Products has a global supply network, breadth of resources, world class service, expert technical assistance, commitment to quality, and an industry-recognized safety record. We understand your need for a secure, reliable supply, coupled with attention to detail and supported by service—throughout the world. Let us help make your business take off.
