LN2 Dosing Systems
Automated liquid nitrogen dosing systems for preservation, pressurization, and freezing in packaging applications. One drop at a time, reducing waste and adding value.
Preservation
Precise LN2 dosing pushes oxygen out of containers, extending shelf life by up to 26% and reducing headspace oxygen by 90-95%.
- Extended shelf life for beverages and oils
- Efficient nitrogen consumption
Pressurization
LN2 vaporizes to create internal pressure, allowing lighter packaging materials and reducing costs by over $2.6M annually per line.
- 9g reduction in PET bottle weight
- Eliminates package paneling
Freezing
Surface freezing locks in product integrity before traditional freezing, maintaining flavor and texture for premium products.
- Maintains product integrity
- Enhanced flavor and texture
