 UltraDoser 350
Cost effective entry level liquid nitrogen injection system
The UltraDoser is the ideal general purpose liquid nitrogen (LN2) dosing system with speed compensated controls for line speeds up to 350 containers per minute.
Typically installed after the filler and before the capper/sealer, the UltraDoser dispenses a measured dose of LN2. Once introduced into the container, it immediately picks up heat and turns into gaseous nitrogen, expanding 700 times in the process. This expansion creates pressure and adds rigidity to the container. For headspace inerting, the rapidly expanding gas is allowed to escape before the product is sealed, flushing oxygen out of the container
