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. 

nitrogen dosing craft beer

Familiar with the upsurge in craft beers and the nitro coffee phenomenon? Chart nitrogen dosing facilitates both.

Preservation

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

Full Equipment 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. 

  1. Storage: complete range of LN2 liquid cylinders, MicroBulk systems and bulk tanks.
  2. Withdrawal: a vacuum insulated valve has the benefit of extremely low heat leak for minimum gas boil-off and eliminates unsafe ice build-up.
  3. Vacuum Insulated Pipe: the foundation for heat loss efficiency and long-term integrity.
  4. Phase Separator: provides extremely high-quality, low pressure LN2 on demand resulting in a continuous supply of unsaturated LN2.
