| Valve type | Isobaric, CO2 counter-pressure |
| Rated output | 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 |
Four points decide it: the carbonation level set at the mixer, the product temperature at the filler, the pressure profile during fill, and the time between capping and packing. A line that holds 4.0 volumes at the mixer can deliver 3.4 in the bottle if the filler bowl runs warm or the capping head leaks.
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.
| 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 |
Throughput and change-part lists are on the CSD & Sparkling Water by Mechanical Filler page rather than in this note.
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.
Rated output, change parts and services are listed 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.
The same question is worked through from another angle in How to Reduce Foam in Semi-Electric CSD Filling Machines.
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.
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.
It is used where the package needs internal pressure support or low oxygen, for example in cans and in some PET formats. It is an option, not a default, and it adds a consumable cost per 1,000 units.
