Water that is described as "hard" is high in dissolved minerals, particularly
calcium and magnesium, which are acquired through contact with rocks and
sediments in the environment. Calcium and magnesium also tend to adhere on pipes
and internal components, and in an evaporative cooler, this can result in
impeded airflow and damage to your unit.
As such, use Port-A-Cool's MK-47-CS Mineral Knockout in your evaporative
cooler to treat hard water conditions that can damage or shorten the life of
your unit's internal components. By regularly adding the MK-47-CS mineral
treatment to the reservoir of your Port-A-Cool, you can prevent hard water
buildup, protect fan components, and even extend the life of your investment!
Note: The MK-47-CS contains six bottles of Port-A-Cool Mineral Knockout.
