Coil Cleaning - Kelvion TEC1 Installation And Maintenance Instructions Manual

19. COIL CLEANING

It is essential that the heat exchanger coil is kept clean to maintain the designed heat transfer rate. General debris such as
leaves, paper, dust and pollen can be removed using a brush, with compressed air blowing against direction of airflow (Max
pressure 3bar) or an industrial vacuum cleaner.
The fin should be brushed in the longitudinal direction of the fins with a soft brush.
Heavier greasy soiling must be removed using a high- pressure water/steam jet washer (Max pressure 3bar) against direc-
tion of airflow, at a distance of 300 to 400mm using a neutral cleaning agent if required.
The jet of the cleaner should be held vertical to the fin bank to avoid fin damage.
Any cleaning fluids should be suitable for use on both tube and fin materials, incorrect use of fluids could be corrosive
towards heat exchanger materials.
