| Where it fits | Still water, RO water, mineral water |
| Filling method | Gravity or volumetric valve |
| Capacity | 5,000-48,000 BPH at 500 ml |
| Bottle range | 200 ml to 16 L, by configuration |
| 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. Change the thread by a millimetre and the rinser clamp and capping head have to change with it.
Implement practices such as 5S (Sort, Set in order, Shine, Standardize, Sustain), Just-In-Time delivery, and continuous improvement to streamline processes and enhance overall performance.
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.
| 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 |
Rated output, change parts and services are listed on the Blow-fill-cap Combibloc for Still Water page.
A lighter bottle is less rigid, so it deforms more under the filling head and grips differently in the star wheels. The filler may need a different neck handling and a lower contact pressure. Lightweighting is a bottle project that reaches into the filling line.
Valve count, utility schedule and footprint sit on the Gravity Filling Machine for Still Water page.
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.
The same question is worked through from another angle in How to Set Up a Complete Water Filling Line.
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. Because volumetric filling doses by chamber volume, accuracy holds across bottle sizes. For one rigid bottle size, gravity is enough; for 3-10 L or mixed formats, volumetric is safer.
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.
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.
