Buying a complete used bottling line is not the same as buying a single machine. The line must handle one product, container and closure from infeed to pallet, while every machine shares the same real operating speed. This guide explains the checks that reduce technical and commercial risk before a purchase.
Start with the product and package
Define the liquid, container material, nominal volumes, neck finish, closure, label type and secondary packaging. Carbonated drinks normally require pressure-rated filling; still products may use gravity, low-vacuum or volumetric filling. Hot-fill, dairy and sensitive beverages add hygiene, temperature and cleanability requirements.
Map the complete line
A complete line may include depalletizing, bottle preparation, rinsing, filling, capping, inspection, labelling, coding, packing, palletizing and conveyors. Ask for the original layout and identify every transfer point. A line advertised at a headline speed can only deliver the output of its slowest machine after normal stops and changeovers.
- Confirm the product and formats previously run.
- List included change parts, manuals, software backups and electrical drawings.
- Check power, air, water, steam and cooling requirements.
- Verify guarding, safety circuits and compliance for the destination market.
- Separate machine price from dismantling, packing, freight, installation and commissioning.
Inspect before committing
Whenever possible, inspect the line connected and running. Review filler valves, capper heads, label stations, bearings, chains, conveyors, lubrication and control cabinets. Record serial plates and software versions. If a wet production test is impossible, request a documented dry test and agree what will be proven during commissioning.
Compatibility matters more than age
A well-maintained line with available spares can be a better purchase than a newer line with the wrong formats or unsupported controls. Confirm that the original manufacturers or qualified specialists can support the installed PLC, drives, safety components and mechanical assemblies. Brand names and model designations should remain unchanged in every technical document.
Plan integration and acceptance
Before shipment, define battery limits, responsibilities and acceptance criteria: container, product, speed, duration, waste, changeover time and utilities. Photograph cable labels and conveyor references during dismantling. A realistic schedule includes foundation checks, unloading, mechanical assembly, electrical work, utilities, dry testing, wet testing and operator training.

Frequently asked questions
What should be included with a used bottling line?
The commercial offer should list every machine, conveyor, control panel, format set, manual and spare part. Items not listed should be treated as excluded.
How do I compare two lines?
Compare them against the same product, container, closure, target net output, utilities, footprint and total installed cost—not only the advertised speed or purchase price.
