Chart Industries

Chart Industries is at the forefront of innovation in the realm of cryogenic technology, particularly renowned for its liquid nitrogen dosing systems and tanks. Leveraging cutting-edge engineering and a deep understanding of cryogenic principles, Chart Industries has developed state-of-the-art solutions that revolutionize industries ranging from food and beverage to pharmaceuticals. With a commitment to precision, efficiency, and safety, their liquid nitrogen dosing systems offer unparalleled control over nitrogen injection, ensuring optimal product quality and shelf life. Complementing these dosing systems are Chart’s robust liquid nitrogen tanks, engineered to store and deliver cryogenic fluids reliably and efficiently, meeting the diverse needs of their global clientele.

Liquid Nitrogen Dosing

CryoDoser FleX Craft Brew

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.


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, canned peanuts, container stabilisation.

Operational savings: documented studies show a 26% increase in shelf life and 90 to 95% reduction in headspace oxygen compared to traditional gaseous nitrogen purging

Container (bottle or can) stabilisation/ pressurisation

A precise dose of LN2 is delivered immediately before capping or seaming. The trapped LN2 quickly vaporises, pressurising the container.

Key Benefits: use of light-weight packaging, increased packaging rigidity, glass to plastic transition, removal of O2 and elimination of container/package panelling, support for labelling application, oxygen reduction

Typical Applications: non carbonated products in bottle or Can (ie. water, wine,…), energy shots, flax seed oil, juices (hot and cold fill), teas, vinegar

Operational savings: documented 9 gram reduction in PET bottle weight with LN2-technology. Assuming the PET resin cost of $0.80/lb and a single production line running at 350 bottles/minute, this equates to an annual cost saving >$1.3 million.
