Filling technology selection
Gravity, Hot-Fill and Isobaric Filling Compared
Gravity and isobaric describe filling-pressure principles; hot fill describes a thermal process. They are not three interchangeable machine modes. Start with whether the beverage contains CO2 and whether its validated process requires hot filling, then match the bottle, closure, cleaning method and output.

Which Filling Route Should You Investigate First?
These are screening examples, not validated production recipes or final model recommendations.
| Project example | Initial route to review | Catalog family / next decision |
|---|---|---|
| Still drinking water in PET | Normal-pressure filling | XGF; confirm treatment outlet, bottle and cap before capacity selection |
| Juice or tea with a validated hot-fill process | Hot-fill-compatible filling and closure sequence | RXGF; confirm recipe, thermal conditions, heat-resistant package and cooling |
| Carbonated soft drink in PET | Isobaric filling | DXGF; confirm dissolved CO2, inlet temperature, pressure and foam acceptance |
| Aseptic, dairy, high-pulp or high-viscosity product | Separate application review | Do not select an XGF, RXGF or DXGF model from beverage name alone |
Machine selection and configuration
Filling principle comparison
| Route | Preliminary fit | Package/process demand | Main risk if inputs are missing |
|---|---|---|---|
| Gravity / normal pressure | Still, low-viscosity products | Stable venting, suitable level control and hygiene path | Foam, slow fill or inconsistent level |
| Hot fill | Validated heat-processed products | Heat-resistant bottle and cap plus cooling/hold sequence | Package deformation or an incomplete thermal process |
| Isobaric | Carbonated beverages | Chilled product, pressure balance and compatible package | Foam, CO2 loss and unstable fill |

Buyer questions
Frequently asked questions
Can two filling principles appear suitable for the same beverage name?
Yes. The actual formulation, carbonation, temperature, flow behavior, package and shelf-life route can change the decision behind a broad beverage label.
Is hot filling the opposite of gravity or isobaric filling?
No. Hot filling describes the product thermal condition and process sequence. Gravity and isobaric describe the pressure principle used to transfer product into the container. A specification must identify both the filling mechanism and the validated thermal process rather than treating the terms as interchangeable machine modes.
