Dosing and purging

Liquid nitrogen dosing (LIN dosing) is a unique process that helps maintain beverage quality and optimum shelf life. Drops of liquid nitrogen introduced in the bottling and canning process help drive out atmospheric air, and reduce oxygen in the liquid.


Air Liquide supplies liquid nitrogen in bulk for dosing and purging applications, as well as related equipment and services.


Our on-site services include process analysis and optimization, installation and start-up support, inspection and maintenance.
