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.
Reducing Waste & Cost One Drop at a Time
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.
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
Pressurization in Packaging
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
Modified Atmosphere Packaging (MAP)
A large dose of liquid nitrogen is introduced into the package seconds before the seamer or capper.
In Operation: 46% reduction in nitrogen consumption using a Chart doser in lieu of traditional nitrogen gas purging
Complete Turnkey Solution
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.
Storage: complete range of LN2 liquid cylinders, MicroBulk systems and bulk tanks.
Withdrawal: a vacuum insulated valve has the benefit of extremely low heat leak for minimum gas boil-off and eliminates unsafe ice build-up.
Vacuum Insulated Pipe: the foundation for heat loss efficiency and long-term integrity.
Phase Separator: provides extremely high-quality, low pressure LN2 on demand resulting in a continuous supply of unsaturated LN2.
