 Inerter
High volume liquid nitrogen dosing for oxygen reduction applications
The Inerter is a high volume LN2 dosing system for full container and headspace inerting applications designed to meet ultra-low O2 specifications in the food and beverage industry.
The Inerter can be installed before the filler for an empty container purge (such as beer applications) or after filling for full container purge and headspace purging (such as wine, salad dressing, juice, nuts, coffee etc.). Once the Inerter dispenses LN2 in to the container, it immediately picks up heat and turns into gaseous nitrogen, expanding 700 times in the process. The rapidly expanding gas is allowed to escape before the product is sealed, flushing oxygen out of the container.
System features

- Easily integrated into new or existing filling lines.
- Accurate, precise high volume dosing.
- Reliable performance.
- No container/no dose feature.
- Sealed vacuum insulation – no vacuum pump required.
- Slim profile dosing head.
- Self-generated GN2 purge at dosing head to minimize moisture intrusion.
- Self-regulating heaters designed for longevity.
- Distribution panel to track performance of each electrical component.
- Minimal utility requirements.
Controller features
- Easy to use touch screen controller requires minimal training.
- Multi lingual support (Siemens option only).
