Plate Heat Exchanger Heat Recovery Systems
The spray machine to be used for heat exchanger cleaning should be at low
pressure. Cleaning with high pressure machines can damage the fins and make the heat exchanger unusable.
•
Loosen wing fasteners and remove service panel.
•
The heat exchanger is cleaned of dust and other contaminants with clean water and low-pressure spray.
•
The cleaning of the rotary heat exchangers is done with Fairy branded dishwashing detergent with a cleaning liquid
to be prepared with a maximum of 75% water-25% detergent.
•
This prepared solution is filled into the low-pressure washing machine and sprayed to the heat exchanger at a
maximum angle of 30 degrees and a minimum distance of 30 cm.
•
The same process should be repeated until the detergent between the coverslips and clean water is completely
cleared.
Cleaning should be done at a maximum angle of 30 degrees. Otherwise, the
coverslips may be damaged!
Cleaning should be done from all 4 sides of the heat exchanger. After the process is over, it should not be placed in the
unit until it is completely dry!
