Liquid nitrogen dosing system named for its size and cost.

  • Discrete dosing for speeds up to 12000 containers/hour.
  • Liquid Nitrogen supply at low pressure (max 1.5 bars) by user.
  • Dosing accuracy : 5%
  • Minimum dosing valve opening time of 25ms.


Base unit including:

  • Fully vacuum jacketed, stainless steel dosing unit. Internal reservoir with mechanical fill level control. Electrical dosing valve. Safety relief valve.
  • Heated nozzle area and gas vent
  • Integrated self generating nozzle purge system. No dedicated nitrogen gas supply required.
  • Remote Siemens S7-1200 control panel with Siemens KTP400, 4” touch screen HMI (230V/50Hz or 115V/60Hz) in stainless steel NEMA 4x rated housing.
  • 6 meter electrical cables. 15 meter cable sets are optionally available.
  • Speed compensation capabilities
  • Speed sensor (proximity).
  • Infrared sensor for bottle detection (Dosing enabled only when container is present).
  • Complete operation and service manual



  • Additional LN2 feed line : standard length is 3 meters from tank to doser. Any additional meter should be ordered in this option. Bayonet couplings will be needed in case of lengths longer than 12 meters.
  • A standard 6 meter cables set from the doser to the PLC is included. Instead, a 15 meter set can be ordered optionally.


  • Stainless steel (height adjustable) support in AISI 304 material (also available in AISI 316 on request). This support can be either on a 2×2 pod or a bottom plate basis.
