| Typical duty | Still water, RO water, mineral water |
| Filling system | Gravity or volumetric valve |
| Output range | 5,000-48,000 BPH at 500 ml |
| Format 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. 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.
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.
| 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 |
Sizing for this duty runs through the Blow-fill-cap Combibloc for Still Water, where the valve count is set out.
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.
The specification sheet for the Gravity Filling Machine for Still Water carries the utility figures quoted here.
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.
The same question is worked through from another angle in 5L Water Bottling Line Ready to Zimbabwe.
A small line gives up automation, not quality. Manual or semi-automatic packing, fewer accumulation buffers, and a simpler CIP usually follow. What it should not give up is the filling valve and the capping head, because those two decide whether the product is saleable.
200 bottles per minute. Divide BPH by 60. A 24,000 BPH line runs at 400 bottles per minute, which is why filler and packer have to be matched rather than bought separately.
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. 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.
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.
