Eleven years inside a Coca-Cola plant

Water arrives from a well and has to be treated before it can touch a product. Syrup is prepared in one part of the building and metered to mixers in another. Filling lines run to a schedule. Everything that leaves the site as wastewater has to meet a discharge standard. Each of these is a separate process, with its own instruments, its own failure modes and its own regulatory paperwork.

They had also been built at different times. Instrumenting a plant like this is rarely a clean-sheet exercise — it means adding visibility to equipment that already runs, from more than one manufacturer, without stopping production to do it.

What the plant needed was not a single system. It needed live values and archived history on the handful of parameters that determine product quality and compliance, in each of those areas, arriving in a form an operator could read at a glance and an engineer could interrogate later.

The part of this the client chose to single out was not the engineering. It was the support model. A bottling plant runs to a schedule, and a control fault at three in the morning is measured in lost product, not in engineering hours — and the plant is a long drive from our workshop in Tešanj.

Remote diagnostics closes that gap. Faults are identified and, in most cases, cleared without anyone travelling — and the same connection that clears a fault is the one used to extend a system rather than replace it. That is why systems commissioned in 2012 were still being improved in 2023.

The last of those jobs is also the clearest ancestor of what Comex builds today: pulling live process values out of a plant and writing them somewhere they can be used. The Comex Control platform solves that same problem across a fleet of sites.
