| Typical duty | Still water, RO water, mineral water |
| Filling principle | Gravity or volumetric valve |
| Output range | 5,000-48,000 BPH at 500 ml |
| Bottle sizes | 200 ml to 16 L, by configuration |
| Wetted parts | SUS 304 product contact, CIP-ready |
| Line scope | Treatment, blowing, filling, capping, labelling, packing |
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.
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.
| 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.
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.
Valve count, utility schedule and footprint sit on the Gravity Filling Machine for Still Water page.
A monoblock carries the rinser, the filler and the capper on one frame with one drive. It removes two transfers, the floor space between them and the bottle handling at each. Three separate machines are easier to replace one at a time and easier to run at different rates.
The same question is worked through from another angle in Comparison of Water Filling Machines for Business Needs in.
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.
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.
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.
