Carbonation retention
CO₂ retention filling machines for carbonated drinks.
Choose a filling route that protects the carbonation level your drink needs in the finished pack.
Customer route
Choose the equipment around the drink, pack and output.
Loss of CO₂ during filling can affect taste, mouthfeel, foam, headspace and customer perception. A counter-pressure or isobaric filling route helps manage the pressure change between tank, filler and container.
- Pressure-controlled filling for carbonation retention
- Bottle and can routes for fizzy drinks
- Useful for soda, beer, water, cider and RTDs
Specification notes
Useful points before requesting a quote.
CO₂ level
State the intended carbonation level or your current process target if you know it.
Temperature
Colder product is often easier to fill with less CO₂ breakout, but chilling must fit your process.
Closure route
Fast, reliable closure helps retain carbonation once the container has been filled.

Questions to ask
Before specifying this route.
How do fillers retain CO₂?
They manage pressure during filling and reduce the sudden release of dissolved gas.
Does product temperature matter?
Yes. Product temperature has a strong effect on foam and carbonation behaviour during filling.
Can CO₂ retention be improved on existing lines?
Sometimes, but it depends on the existing filler, product handling, temperature and closure process.
