| Where it fits | Still water, RO water, mineral water |
| Filling system | Gravity or volumetric valve |
| Capacity range | 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 |
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. 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.
Regular calibration checks are necessary to account for factors such as temperature variations, viscosity of the water, and wear and tear on the equipment.
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.
Optimal speed settings need to be carefully calibrated based on the specific requirements of 5-15L bottle 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 |
Throughput and change-part lists are on the Blow-fill-cap Combibloc for Still Water page rather than in this note.
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.
Effective handling of large 5-15L water bottles by mechanical fillers requires a meticulous focus on valve design, speed, and calibration.
The unit behind this configuration is the Gravity Filling Machine for Still Water.
A water line is cleaned on a fixed cycle plus a changeover clean. The circuit covers the filler bowl, the product pipes and the filling valves. Ozone or heat is used for disinfection, and the cycle time is a planned stop rather than an incident.
The same question is worked through from another angle in The Importance of Water Quality for Bottled Water Production.
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.
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.
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.
