Causes of wear on Heat Exchangers

There are a lot of factors that can cause Heat Exchangers to wear down. Causes such as fouling, erosion and corrosion are the most common.

Find out below on what are the different causes of wear on Heat Exchangers.


Fouling is a build-up of unwanted materials on the surface of a Heat Exchanger. The sediment can insulate critical surfaces, reducing the rate at which heat can be transferred through them, reducing the efficiency of the process.

Certain environments can cause heat exchangers to get dirty faster than usual. For example, An environment with lots of dust can lead to a build-up of dirt.


Erosion is where the flow of the fluid passing eats up the surface of the tube from which it is running through it. This effect can be fastened by the presence of particles such as sand or silt in the fluid, which can remove material much faster. This can cause the tube wall thinning and ultimately leaks.


Corrosion is also an issue. Coolants and other mediums can corrode the metals in a heat exchanger, damaging them over time and leading to residues that clog the heat pipes.

With all of this in mind we recommend implementing a routine cleaning and inspection of your Heat Exchanger in order to prevent wear.
