How do I clean my air inlet louvers?

Cooling towers can often experience mineral/scale buildup on the exterior surfaces of their air inlet louvers. Improper water treatment, insufficient bleed rates, and/or excessive cycling of the fan motors are the most typical causes. Since the louver material is constructed of lightweight PVC, it cannot withstand the rigors of heavy mechanical cleaning.  Therefore, DO NOT USE A WIRE BRUSH OR PRESSURE WASHER TO REMOVE THE MINERALS/SCALE FROM THE AIR INLET LOUVERS. This method of cleaning will damage and/or destroy the louvers.
