Heat exchanger cleaning by industry
Fouling follows the process. What builds up in a brewery paraflow has nothing in common with what builds up in a crude preheat train, and the two are not cleaned the same way.

Every sector has its own deposit and its own constraint on when work can happen
The deposit is the obvious difference. Seawater duty grows barnacle spat; a pasteuriser lays down denatured whey protein at one temperature and calcium phosphate at another; a crude preheat train cokes; a digester heating loop crystallises struvite. Each of those needs different chemistry, different tooling and in several cases a different trade, and a contractor who cleans one well is not automatically set up for another.
The less obvious difference, and usually the more important one, is the constraint on when the work can happen at all. A vessel sails. A refinery opens its exchangers at turnaround and at no other time. A brewery already cleans its plant every day and calls a specialist only when that has stopped working. A pharmaceutical site cannot touch qualified equipment without change control. A data centre never stops. Those constraints shape the method more than the deposit does.
Each page below is written for one sector: the units it runs, the deposits it gets, the constraint it works under, and the questions its engineers ask. None of it is the same page with the nouns changed.

Twelve sectors, each with its own equipment and its own deposits
A specialist who cleans that unit type answers the request
Unit, deposit and postcode are enough to start. Your details go to a specialist who cleans that unit type. No obligation.
