LN2 Dosing Systems

Chart Dosers, a division of Chart Inc., has a complete line of liquid nitrogen (LN2) dosing equipment to dosing systems for inerting/nitrogen flushing and pressurization applications.

Using advanced cryogenic technology, Chart engineers designed an ultra-efficient, double walled, sealed vacuum unit likened to a "high-tech thermos". Typically installed after the filler and before the capper/sealer, it dispenses a measured dose of LN2. Once the LN2 (-320F/-196C) is introduced into the container, it immediately picks up heat and turns into gaseous nitrogen, expanding 700 times in the process. When trapped inside the container, the gaseous nitrogen creates pressure and adds rigidity to the container. For headspace inerting applications, the rapidly expanding gas is allowed to escape before the product is sealed, flushing oxygen out of the container.

Chart provides value-added insight to your production operations. Our application engineers have a wealth of practical LN2 dosing knowledge from hot-fill PET bottles, aluminum tubes, and glass to plastic conversions. We also have experience with a wide variety of products from water to wine; peanuts to pie filling; and ice cream to iced tea.

All systems are easy to operate and can be integrated into new or existing lines. Find out how Chart can help you reduce operating costs, prolong shelf life, and improve product integrity.
