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.

The ‘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. However, Chart has worked out how to remove the widget, and that is a huge deal because it affords significant cost savings and efficiency.
