Nitrogen Shrouding

Nitrogen shrouding of food steel tanks and containers oxidation is an essential step to prevent oxidation of its contents (deoxygenation).This step is usually performed in a nitrogenisation chamber.

This is particularly the case for vitamins and powders containers in general,or even wine (or grapes) containers in the wine industry.

This inerting system makes it possible to make a primary vacuum and to process several containers simultaneously. Nitrogen pumping and pressurization cycles are automated and managed by an automated system.
