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.
A widget is used to create the same effect when the can is opened as when it’s poured from a nitro tap. Nitrogen is released and it agitates the beverage.
Familiar with the upsurge in craft beers and the nitro coffee phenomenon? Chart nitrogen dosing facilitates both.
For those that want to know more, we offer learning opportunities with our informational webinars.
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
From initial design to a complete after-sales package, we work closely with our customers to ensure that the complete system is engineered and built in accordance with their requirements and always operating at peak efficiency.

of clean drinking water
With the donation of Chart dosing equipment Can’d Aid has provided >3.1 million cans of clean drinking water throughout the U.S., including Puerto Rico and Navajo Nation, in response to natural and human-made disasters. Can’d Aid volunteers distribute water providing access and opportunities to underserved youth, and protecting and restoring the environment.
