Used soft drink machines cover the whole CSD chain: premix and proportioning systems, carbonators and saturators, isobaric counter-pressure fillers, PET stretch blow moulders, screw cappers, labellers and shrink wrappers.
Carbonation level, product temperature and filler pressure are specific to the product and the process, so the useful question is always how a given machine was configured and what it was running before.
Buying Guide — Used CSD Bottling Machines
On a premix or saturator, look at the dosing architecture, the carbonation system, hygienic design and CIP capability, and any performance or maintenance records available for that unit.
On an isobaric filler, check the rated pressure against your product and process, counter-pressure valve and seal condition, fill-level control, and how the machine synchronises with the blower or container feed upstream.
For PET, confirm blower and neck-finish compatibility with your preforms, and list the mould sets, closure tooling and container change parts included with the machine.
Frequently asked questions
What does a premix and saturator system do?
It blends water and syrup and carbonates the mixture before the filler. The blend ratio and carbonation level depend on the product being produced.
What should I verify on a used isobaric CSD filler?
Rated working pressure against your product and process, valve and seal condition, fill-level accuracy, CIP capability and container and closure tooling.
Can a CSD filler run still products?
Sometimes, subject to engineering review of the specific machine and its valves. Check the configuration of the individual filler rather than assuming.
