Water Quality Guidelines For Evaporative Cooling Products
In evaporative cooling products, cooling is accomplished by evaporating a small portion of the recirculating water as it flows through the unit. As this water evaporates, the dissolved solids originally present in the water remain behind and, if not controlled, their concentration will increase rapidly. This can lead to corrosion, scale, or biological fouling which may negatively affect heat transfer as well as the longevity of the unit and other system components.
