Just like a car or a computer, a heat exchanger needs regular maintenance to keep running at peak performance. Fortunately, PHE’s are generally easier to maintain than other types of heat exchangers, and problems tend to be easier to diagnose.

This article is dedicated to identifying issues your plate heat exchanger (PHE) might be having, and setting you on the path to the right solution. Nearly all issues boil down to some form of plate fouling or gasket failure, but it’s important to determine whether it’s a one-time problem or an inherent flaw in your system (the PHE is specified incorrectly). The first step is to identify the symptoms of your underperforming heat exchanger.
