A carbonated drink is a saturated solution held in equilibrium by pressure and temperature. If the filler exposes it to atmosphere, CO2 leaves the liquid as foam and the fill level collapses. Isobaric filling pressurises the bottle to the bowl pressure first, fills under counter-pressure, then releases in a controlled ramp.
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.
| 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 |
The CSD & Sparkling Water by Mechanical Filler is the reference unit for this configuration.
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.
Sizing for this duty runs through the Isobaric Filling Machine for CSD and Sparkling Water, where the valve count is set out.
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 Order for sparkling water bottling line from Turks and.
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.
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.
The higher the volumes, the sharper the mouthfeel and the more pressure the package must hold. Higher carbonation also needs a colder fill and a tighter pressure ramp, so it reduces practical line speed.
Yes, with a different infeed, spacing and capping set. Glass needs mechanical spacing rather than an air conveyor, and the filler runs at 4,000-20,000 BPH on glass against 12,000-36,000 BPH on PET.
