Four key liquid nitrogen dosing applications

Choose the application that matches your product and download the brochure for Chart LN₂ dosing systems.

01

Preservation

A precise LN₂ dose is introduced immediately before sealing. The nitrogen vaporizes and displaces oxygen from the headspace, supporting product quality and shelf life.

Applications: beer, wine, oils, condiments and oxygen-sensitive products.
02

Pressurization

The dosed LN₂ rapidly vaporizes inside the sealed package and creates controlled internal pressure, enabling lighter and more stable PET bottles and cans.

Applications: water, juices, teas, energy drinks and hot-filled products.
03

Freezing

Liquid nitrogen rapidly surface-freezes the product before it enters a tunnel or spiral freezer, helping preserve shape, texture and appearance.

Applications: ice cream and products requiring stability during packaging.
04

Modified Atmosphere Packaging (MAP)

A larger LN₂ dose is introduced immediately before sealing to reduce oxygen and gaseous-nitrogen consumption.

Applications: coffee, nuts, botanicals, powders and food products.
