| Typical duty | Still water, RO water, mineral water |

| 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. BPH takes the meeting; the neck finish and the capper match get the last five minutes. Rinser clamps and capping heads are cut for one neck finish; a 1 mm thread change means new change parts rather than a new machine.
Gravity filling holds a level in a rigid bottle and costs least per valve. Volumetric filling doses a fixed volume into a chamber, so it holds accuracy across 3 L, 5 L and 10 L formats without changing the head. Isobaric filling is for carbonated product only, because it keeps CO2 in solution under counter-pressure. A still water line never needs it.
This order includes rinsing-filling-capping 3-in-1 monoblock, cap loader, cap washer and 6m bottle conveyor.
| 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 |
Throughput and change-part lists are on the Blow-fill-cap Combibloc for Still Water page rather than in this note.
Work backwards from cases per day. Divide bottles per day by productive hours, then divide again by a production factor of 0.65-0.85. The factor covers changeover, CIP, label roll changes and downstream stops. Sizing at 1.0 is the most common and most expensive mistake in a water project, because the shortfall only appears once the line is running.
The Gravity Filling Machine for Still Water is the matching unit when this becomes a line project.
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.
The same question is worked through from another angle in The Fundamentals of Pump Selection for Water Filling and.
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.
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.
Commercial practice is a stated band per bottle size, typically checked by weight at the filler outlet. The band belongs in the acceptance protocol. A line without a written tolerance will argue about it at commissioning.
