Inspecting the Heat Exchanger
Maintenance
6. Begin with an external inspection of the heat exchanger. Visually inspect
for:
•
Corrosion
•
Signs of a previous repair
•
Leakage
7. A marked decrease in pressure and/or reduction in performance usually
indicates cleaning is necessary. The following are suggested methods of
cleaning either side of the heat exchanger.
•
Back-flush the heat exchanger with a high pressure stream of hot water
to remove loose deposits
•
Circulate hot wash oil or light distillate to remove sludge or similar soft
deposits.
•
To remove more stubborn deposits, use a commercial cleaning
compound. Follow the manufacturers instructions for using the
cleaning compound.
Important
It is recommended that you contact a representative of the
manufacturer of the cleaning compound to determine the correct
cleaning compound for your type of scaling problem and its
compatibility with the metals and alloys used in the heat exchanger.
8. If the heat exchanger is excessively fouled and cannot be cleaned using the
commercial cleaning methods, then replacement of the heat exchanger is
recommended.
