| Typical duty | Still water, RO water, mineral water |
| Filling method | Gravity or volumetric valve |
| Rated output | 5,000-48,000 BPH at 500 ml |
| Container range | 200 ml to 16 L, by configuration |
| Contact material | SUS 304 product contact, CIP-ready |
| Line scope | Treatment, blowing, filling, capping, labelling, packing |
Raw water, neck finish and the filler-capper match decide more about a water line than its BPH. Most of the meeting goes on BPH; the other two get a fraction of the time. Change the thread by a millimetre and the rinser clamp and capping head have to change with it.
Star wheels, guide rails, grippers, cap chute and filling recipe all change with the format. The parts are not the cost; the time is. Two formats on one line typically cost 40-90 minutes per switch, which is why the production factor falls from about 0.85 to 0.70 and why a second small line is sometimes cheaper than one flexible line.
| Filling principle | Best for | Watch out for |
|---|---|---|
| Gravity | Still water, one rigid bottle size | Thin-wall bottles deform under head pressure |
| Volumetric valve | 3-15 L and mixed formats | Valve wear shows as slow drift, not a sudden error |
| Isobaric | Carbonated water only | Needs counter-pressure, so slower per valve |
| Load cell | Oil and high-value liquid | Slower cycle, higher cost per valve |
The Blow-fill-cap Combibloc for Still Water is the matching unit when this becomes a line project.
Ask for the rated capacity of the slowest station, the changeover checklist, the CIP cycle time, and the water and power consumption per 1,000 bottles. Those four numbers decide the real cost per bottle. A quotation that lists only the filler capacity and a total price leaves the buyer comparing incomparable offers.
The Gravity Filling Machine for Still Water is the reference unit for this configuration.
Mineral water is defined by its source and its mineral profile, so treatment is limited to what the label claim allows. Purified water starts from any feed and is built up to a specification. The filling machine is the same; the treatment train and the legal claim are not.
The same question is worked through from another angle in How to Optimize Your Water Filling Line for Maximum.
It follows the raw water analysis, not a standard package. Surface water usually needs multi-media filtration, RO and UV or ozone. Low-hardness municipal water may need only carbon filtration and disinfection.
Plan for 380 V three-phase power, 0.6-0.8 MPa compressed air, and a chiller if blow molding runs in-house. Exact consumption belongs in the utility schedule of the quotation, not in a rule of thumb.
For a complete line with blowing, filling, labelling and packing, plan several weeks on site after arrival, plus operator training. Civil work and utility readiness are the usual delay, not the machinery.
Not on the same filler. Carbonation needs isobaric valves, a CO2 dosing and mixing unit, and a different bowl. A combiblock can carry both valve sets, but they are separate specifications, not a field conversion.
