| Where it fits | Still water, RO water, mineral water |
| Filling principle | Gravity or volumetric valve |
| Capacity | 5,000-48,000 BPH at 500 ml |

A water line stands or falls on three inputs: raw water analysis, neck finish, and how well filler and capper are matched. 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.
In the realm of bottled water production, the efficient filling of large 5-15L bottles is a critical process that demands precision and reliability.
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.
Different valve types are available to cater to varying viscosity levels and container sizes.
| 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 reference unit for this configuration.
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.
Sizing for this duty runs through the Gravity Filling Machine for Still Water, where the valve count is set out.
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.
The same question is worked through from another angle in Order for two bottled water lines from New York.
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.
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.
