Cryogenic packaging equipment
Liquid Nitrogen Dosing Systems for Food & Beverage Packaging
Precision LN2 dosing equipment for container pressurization, oxygen reduction, inerting, and packaging line performance. Cryotools helps you select, install, and support the right dosing system for your production process.
What LN2 dosing does
More control at the point of packaging
Liquid nitrogen expands into gas inside the container. With the correct dose and timing, it can add package rigidity, reduce oxygen in headspace, support lightweight containers, and improve consistency before sealing.
Precise dose control
Tune dose timing and volume to your product, container, and conveyor speed.
Packaging protection
Support container rigidity, reduce paneling risk, and protect product quality.
Production-ready integration
Connect dosing with the equipment and controls already running on your line.
