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
A precise dose of LN2 is delivered immediately before capping or seaming. The trapped LN2 quickly vaporizes, pressurizing the container.
Key Benefits: lighter weight packaging, increased packaging rigidity, glass to plastic transition, eliminates package paneling, ease of labeling, oxygen reduction
Typical Applications: bottled water, energy shots, flax seed oil, juices (hot and ambient fill), teas, vinegar
In Operation: documented 9 gram reduction in PET bottle weight with Chart's MicroDose™ technology. Assuming the PET resin cost of $0.80/lb and a single production line running at 700 bottles/minute, this equates to an annual cost saving >$2.6 million.
A dose of liquid nitrogen is introduced to "lock in" and surface freeze the product before it's transferred to a traditional tunnel or spiral freezer.
Key Benefits: maintains product integrity, aids in packaging and labeling, enables new products to be brought to market, enhances flavor and texture
Typical Applications: dipped ice cream cones and iCream Café
In Operation: liquid nitrogen flash freezing of ice cream cones provides stability and support through the packaging process resulting in improved overall aesthetics
A large dose of liquid nitrogen is introduced into the package seconds before the seamer or capper.
Key Benefits: extended shelf life, oxygen reduction, reduced nitrogen consumption, stabilization of organic products
Typical Applications: baby formulas, coffee, nuts, trail mix, botanicals
In Operation: 46% reduction in nitrogen consumption using a Chart doser in lieu of traditional nitrogen gas purging

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.
