How Much Evaporative Cooling Pad Do I Need?
One of the advantages of having a tunnel-ventilated poultry house is that you can use evaporative cooling pads to reduce the temperature of the incoming air. Evaporative cooling pads resemble paper air filters and are placed over the large air inlets in a tunnel-ventilated house. They are wetted using fogging nozzles or by dripping water over them. As the air drawn in to the house by the tunnel fans moves through the wetted pad, water evaporates off the pad reducing the temperature of the air.
