| Filling method | 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 |

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 unit behind this configuration is the Isobaric Filling Machine for CSD and Sparkling Water.
Overfoaming is gas leaving the product too fast at the end of fill. The pressure release has to be ramped, not dumped, and the fill height has to leave the right headspace. A snift valve that opens too early turns a good fill into a wet bottle.
The same question is worked through from another angle in 12000BPH Carbonated Bottling Line to Russia.
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.
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.
