| Filling principle | Isobaric, CO2 counter-pressure |
| Capacity range | 12,000-36,000 BPH at 0.2-2 L |
| Containers | PET bottle, glass bottle, aluminum can |
| CO2 handling | Pre-pressurisation and return pipe, no venting |
| Valves | Mechanical, semi-electric or volumetric |
| Line scope | Water treatment, syrup mixing, carbonation, filler, pack |
Mechanical valves open and close on a fixed cam profile and are the most forgiving on maintenance. Semi-electric valves use a signal to open and close, so the fill window can be set per recipe. Volumetric valves dose a chamber and hold accuracy when bottle pressure or product temperature drifts during the shift.
Semi-electric valve filling machines excel in this regard by offering precise control over the filling speed and pressure.
Size the filler on peak shift demand with a production factor of 0.65-0.85, then size the CO2 supply on average consumption, not peak. A CO2 plant built for the filler nameplate runs partly loaded for most of the year and loses more gas to vaporisation than the line saves in speed.
As the demand for sustainable practices grows in the beverage industry, bottled water plants are under increasing pressure to adopt eco-friendly technologies.
| Valve type | Setting | Best for |
|---|---|---|
| Mechanical | Fixed cam profile | Single product, long runs |
| Semi-electric | Signal-timed open and close | Recipe changes within one product family |
| Volumetric | Chamber dose | Pressure or temperature drift during the shift |
| Isobaric + volumetric | Chamber dose under counter-pressure | High CO2 with tight fill accuracy |
Valve count, utility schedule and footprint sit on the Isobaric Filling Machine for CSD and Sparkling Water page.
Syrup is proportioned and blended with treated water, then carbonated under pressure and temperature control. The ratio accuracy and the carbonation stability decide the product, and both are upstream of the filler. A filler cannot correct a drifting blend.
Site requirements, air and water consumption sit with the CSD & Sparkling Water by Mechanical Filler.
A can is filled and seamed, a PET bottle is filled and capped. Cans run faster per unit and are counted in CPH; PET allows larger formats and a lighter package. The filler principle is the same isobaric one, the closing equipment and the line rate are not.
The same question is worked through from another angle in How to Integrate Blow-Fill-Cap Machines in CSD Production.
No. Carbonation needs isobaric valves under counter-pressure; still water runs gravity or volumetric. A combiblock can carry both valve sets, but they are specified separately and are not interchangeable at the push of a button.
It holds what the mixer sets and the temperature allows. Most CSD runs between 2.5 and 4.0 volumes, with the target set per product. Retention, not the mixer set point, is what the acceptance test should measure in the filled bottle.
Usually product temperature rising in the bowl or a worn valve seal. Both change the pressure balance, so the fill cuts off earlier. Log bowl temperature and fill weight together for one shift before changing any valve.
400 cans per minute. CPH and BPH are different units and cannot be compared directly, because can and bottle formats carry different volumes and different downstream equipment.
