| Typical duty | Still water, RO water, mineral water |
| Valve type | Gravity or volumetric valve |
| Rated output | 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 |
Raw water, neck finish and the filler-capper match decide more about a water line than its BPH. 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.
As a decision-maker in the bottled water industry, the choice of a 3-15L bottle water filling machine is paramount to production efficiency and output quality.
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.
One of the primary factors to evaluate when purchasing a water filling machine for 3-15L bottles is the production capacity it offers.
| 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.
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.
Choose a water filling machine that offers flexibility in accommodating different bottle sizes within the 3-15L range.
Site requirements, air and water consumption sit with the Gravity Filling Machine for Still Water.
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.
Investing in a high-quality water filling machine for 3-15L bottles is a strategic decision that can have a significant impact on your bottling plant's efficiency and productivity.
The same question is worked through from another angle in Latest Trends in Water Filling Machine Technology in 2025.
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.
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.
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.
