VII. Maintenance
Kooltronic Air-Cooled Heat Exchangers are designed to require only routine cleaning
of air filters and the heat exchanger element to assure unimpeded airflow through the
heat exchanger element. It is not possible to recommend specific filter cleaning
intervals since the level and the nature of air borne particulate matter differs widely
with each installation. It is generally sufficient to remove and wash the reusable alu-
minum mesh air filter when the outer surface of these filters appear covered with a thin
layer of dust or lint. Filter recoating adhesive is recommended. Appropriate dis-
posable filters are available from Kooltronic.
If filter service is neglected or delayed, the heat exchanger will not perform at its design
capacity. The first indication of excessively clogged air filter is usually a gradual
increase of temperature within the equipment cabinet. Continued operation under
these conditions will cause damage, shorten blower motor life and void the warranty.
