- Virtually maintenance free liquid nitrogen dosing system for high speed lines.
- Discrete dosing for speeds up to 75.000 bottles/hour and 120.000 cans/hour, continuous flow for higher speeds
- Precision metering during steady stream without nozzle changes
- LN2-supply at max 7 bars = Suitable for typical bulk tank supply without need for dedicated phase separator
- Dosing accuracy : 1%
- Minimum dosing valve opening time of 5ms for easy adjustability of dosed quantity at all line speeds.
- Exceptional long-life servo actuator
