9.9 Water side exchanger
It is very important for the exchanger to be able to provide the maximum thermal exchange, therefore it is essential for the inner surfaces to
be clean of dirt and incrustations.
Periodically check the dierence between the temperature of the supply water and the condensation temperature: if the dierence is greater
than 8°C–10°C it is advisable to clean the exchanger.
The clearing must be eected:
•
with circulation opposite to the usual one
•
with a speed at least 1,5 times higher than the nominal one
•
with an appropriate product moderately acid (95% water + 5% phosphoric acid)
•
after the cleaning rinse with water to inhibit the action of any residual product
