A liquid nitrogen doser is selected for a specific line: by product, container, filling speed and nitrogen source. Steiner Ukraine, exclusive representative of Vacuum Barrier Systems (VBS) in Ukraine, Kazakhstan, Uzbekistan, Azerbaijan, Armenia, Kyrgyzstan, Tajikistan, Moldova and Turkmenistan, supplies NITRODOSE®, EasyDose™, MiniDose, Linerter and HS Aseptic dosers made by Vacuum Barrier Corporation (USA).
The engineer needs five groups of parameters. The more precise the data, the more accurate the model and payback calculation.
| Parameter | What to specify | What it affects |
|---|---|---|
| Product | Water, juice, tea, oil, wine, beer, dairy | Goal: pressure, inerting or both |
| Container | PET, glass, can, pouch; volume; preform weight | Dose, need for 3-D Technology |
| Line speed | Containers per minute, planned growth | Model: up to 200, 450 or 2000 cpm |
| Filling | Cold, hot, aseptic | Model and options (HS Aseptic, 3-D) |
| Nitrogen source | Dewar, outdoor tank, existing pipeline | Supply configuration: SEMIFLEX, CobraFlex, separator |
Trials on the customer's line are possible individually, on request. Terms are agreed per project.
The price depends on the model, options, control platform (Siemens or Allen Bradley) and nitrogen supply configuration, so the cost is calculated in the quotation after selection. For budgeting, the payback period matters more: according to VBS, the investment in a doser typically pays back within the first year of operation. The actual period depends on output, product, container and raw material prices.
A detailed comparison is in How to choose a liquid nitrogen doser.
Steiner Ukraine supplies VBS equipment to Ukraine, Kazakhstan, Uzbekistan, Azerbaijan, Armenia, Kyrgyzstan, Tajikistan, Moldova and Turkmenistan.
Yes. The doser is mounted on the filling line and doses nitrogen before or after filling, ahead of capping. The mounting position is defined during selection.
Commissioning and installation supervision are carried out individually, on request, and quoted separately.
