Dosing and purging

Liquid nitrogen dosing (LIN dosing) is a unique process that helps maintain beverage quality as well as optimum shelf life. Drops of liquid nitrogen are introduced in the bottling and canning process to 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.
