RE: Chemical cleaning of heat exchangers

The manufacturer should be able to provide a recommended cleaning flow rate for the exchanger, while a company that supplies cleaning chemicals should be able to suggest the chemicals to use (depending on the type of fouling, and gasket/exchanger material).

RE: Chemical cleaning of heat exchangers

Consider the fluidized bed heat exchanger which is a self cleaning heat exchanger. See http://rccostello.com/klaren.html
If you are down once per month for cleaning this may be a possible answer to your problem.
