A water line stands or falls on three inputs: raw water analysis, neck finish, and how well filler and capper are matched. 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.
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.
| 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 |
Valve count, utility schedule and footprint sit on the Blow-fill-cap Combibloc for Still Water page.
Above 2 L the fill time per valve grows faster than the valve count, so capacity per valve falls and the conveyor has to carry more mass. Handles, cap size and bottle rigidity also change. A 5 L line is usually specified around that format rather than shared with a 500 ml line.
Rated output, change parts and services are listed on the Gravity Filling Machine for Still Water page.
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 Beverage Production in Saudi Arabia and the GCC: Certification.
Temperature, valve wear and bottle variation, in that order. Water is less sensitive than oil, but a warm product foams more and a worn valve closes late. Weighing a sample every few hours catches the drift before it reaches the customer.
Yes, with change parts: star wheels, guide rails, grippers and a filling recipe. Budget 40-90 minutes per switch and expect the production factor to drop from about 0.85 to 0.70.
Gravity holds a fill level, so accuracy depends on bottle geometry. A volumetric filler measures a chamber volume, which keeps it accurate when the format changes. For one rigid bottle size, gravity is enough; for 3-10 L or mixed formats, volumetric is safer.
It depends on whether blowing, packing and palletizing sit in the same hall. Fix the footprint by drawing the layout at 1:100 with conveyor radii included, then check the turning radius of the largest format.
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.
