Nitrogen

Meeting industry’s nitrogen supply needs.

Air Liquide supplies liquid and gaseous nitrogen to every industry. For example, chemical industries and industrial plants require large volumes of gaseous nitrogen to purge out oxygen and moisture in blanketing operations. The food and beverage industry requires varying quantities of both liquid and gaseous nitrogen for food processing and packaging applications and to help maintain safe temperatures while food products are stored and transported.

Air Liquide is a leading supplier of industrial compressed nitrogen gas, industrial liquid nitrogen, and onsite production of industrial nitrogen in a range of purities and concentrations.

Laser Cutting and Plasma Cutting

Industrial nitrogen is an inert gas used for laser and plasma cutting of different materials such as Stainless Steel and Aluminum. Industrial nitrogen keeps the surface of the metal free of oxidation maintaining the metal’s original surface colour (minimises the black residue caused by oxidation).
