Chart - Liquid Nitrogen Dosing System
Chart`s liquid nitrogen dosing systems are used in the packaging of a wide range of products for preservation, pressurization and freezing. Key benefits are extended shelf life, reduced weight and enhanced product quality.
One part of liquid nitrogen (LN2) warms and expands into 700 parts of gaseous nitrogen at ambient temperature. Chart`s automated dosers dispense a precisely measured dose of LN2 into each container prior to sealing. The trapped LN2 vaporizes, creating pressure, and adding rigidity to the container – allowing for a thinner container wall.
Preservation, pressurization, freezing; learn more about the 3 key features Chart nitrogen dosing systems bring to your production line and the attendant benefits in cost, efficiency and sustainability.
An exact dose of liquid nitrogen is introduced seconds before the seamer or capper. The volumetric expansion of the vaporized nitrogen pushes oxygen out of the container.
Key Benefits: oxygen reduction, extended shelf life, efficient nitrogen consumption, stabilization of organic products
Typical Applications: automobile oil, beer, condiments, wine
In Operation: documented studies show a 26% increase in shelf life and 90 to 95% reduction in headspace oxygen compared to traditional gaseous nitrogen purging
