Direct Evaporative Cooling Put simply, whenever water is evaporated, heat is absorbed. This basic principle underlies the design of the MasterCool direct evaporative cooler. High Quality Construction Hot-dipped galvanized steel, welded for maximum strength is combined with our exclusive POLYBOND® finish that protects the whole system – cabinet pans, distributor covers, louvers, and all other parts contacting water. The electrostatically applied polyester epoxy powder-based coating is cured at hi

Conveniently. Automatic Comfort at Your Fingertips. Benefits Saves energy by operating cooler only when needed. Can be used with any brand or type of evaporative cooler. Provides continuous comfort. Set the thermostat and forget about it. Easy to use. No programming required. Pre-wet cycle with start delay allows pads to pre-wet before blower engages so energy efficiency is maximized with optimum cooling. Dual voltage for convenient adjustment. Electrical Specifications Input Voltage 120

What is so special about the MasterCool Pad? The MasterCool evaporative pad is constructed of special cellulose material designed to give high absorbency with strong resistance to deterioration, extending the life of the pad and saving money. The cross-fluted design continually directs water to the air-entering side, inducing a highly turbulent mixing of air and water for optimum evaporation and maximum cooling efficiency. Isn’t Evaporative Cooling just for dry desert climates? While evaporative

Models shown with three ICM’s at each inlet location. The Indirect Cooling Module Outside air is drawn into the ICM. A fan draws air through the inside of vertical fi ns (which have water running inside them). The air picks up heat and is expelled from the ICM while the fins are cooled by evaporation. Other outside air is drawn across the outside surfaces of the cooled fins, and is cooled without coming in contact with water. This cooled air, with no humidity added, then enters the direct evapor
