Industrial Gases

Oxygen is commonly used in metal fabrication applications such as smelting, cutting and welding. Oxygen is also offered as a pure specialty gas under the brand ALPHAGAZ™, which is suitable for critical laboratory and analytic applications. 

The ARCAL^TM brand pure argon and gas mixtures is available in four ready-to-weld products that cover practically any welding application. Each one is designed to be easy to use, reliable and efficient, when and where you need it. 

In laboratories, ultra-high purity ALPHAGAZ^TM brand argon is engineered for gas chromatography, zeroing and other analytical and process control applications. 

Food-grade carbon dioxide is used in carbonated beverages and for food processing applications such as chilling and freezing, modified atmosphere packaging and cold transportation.

Acetylene is a fuel gas that is used together with oxygen for welding metals and cutting steel, and also for allied oxy-acetylene processes for heating, forming and treating metals.

Used in a fuel cell, hydrogen combines with oxygen from the air to produce electricity, generating water as its only by-product. Air Liquide is present across the entire hydrogen supply chain, from production to storage, distribution and the development of end-user applications – thus helping to drive the widespread use of hydrogen as a clean energy to power materials handling, consumer automobiles and mass transportation.

Hydrogen is also offered as a pure specialty gas under the brand ALPHAGAZ^TM, which is suitable for critical laboratory and analytic applications.

Aside from that, Helium is chemically inert and can be used to create an inert atmosphere for Tungsten Inert Gas (TIG) or Metal Inert Gas (MIG) welding. It is also used for purging, annealing, sputtering, leak checking and etching applications in the Electronics industry. 

Helium gas with oxygen in diving tanks prevents the narcotic effect of nitrogen in deep waters. Industries with operations offshore rely on diving gases and breathing mixtures for subsea work.

The ALPHAGAZ^TM brand of pure helium has purity of up to 99.9999%, perfect for critical laboratory and analytic applications. 

Air is essential for combustion, decay and various industrial processes - including oxidation. It is often used for powering rotary equipment and atomize, spray, sand blast, agitate and cool equipment.
