Four inputs fix the shortlist: the product, the package, the daily demand and the number of formats per week. Everything else, including the brand of the PLC, is a detail that can be settled after those four are written down.
As global demand for purified and alkaline water continues to climb, plant managers in 2026 are facing a new reality: the need to balance ultra-high-speed production with increasing pressure for sustainable, energy-efficient, and "intelligent" manufacturing.
Raw water, neck finish and the filler-capper match decide more about a water line than its BPH. BPH takes the meeting; the neck finish and the capper match get the last five minutes. Change the thread by a millimetre and the rinser clamp and capping head have to change with it.
This ensures a consistent mineral profile while reducing wastewater discharge by up to $25\%$.
| 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 specification sheet for the Gravity Filling Machine for Still Water carries the utility figures quoted here.
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.
The Volumetric Filling Machine for Still Water is the reference unit for this configuration.
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.
Lower TCO (Total Cost of Ownership): With a single interface and fewer moving parts than a traditional linear line, maintenance costs are reduced by $15\text{--}20\%$, and energy consumption drops significantly due to the elimination of high-powered air blowers for conveyors.
The same question is worked through from another angle in How to Improve Water Filling Accuracy with Advanced Sensors.
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.
At speeds of 24,000 to 48,000 BPH, mechanical errors can lead to massive product loss.
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 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.
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.
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.
