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 compressed nitrogen gas, liquid nitrogen, and onsite production of nitrogen in a range of purities and concentrations.

Laser Cutting and Plasma Cutting

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

Our solution:  LASAL branded gases include assist gases specially manufactured to high quality standards and supplied in a range of modes to maximise efficiency and reduce waste.
