What is the best method to use to remove heavy scale and fouling from the plates of a heat exchanger?
The plates should be put in water with qualified cleaning chemicals, and use a soft brush, or high-pressure cleaner with care.
There are two major rules to be strictly followed while chemically cleaning any heat exchanger:
- Pay very close attention to the type of the chemical, it must be approved to be used with the material of your plates.
- Never exceed the prescribed time of chemical circulation.
If the above rules neglected, plates may be damaged. Such cases are not so rare, unfortunately.
