Evaporative Cooling Options for Tunnel-Ventilated Houses...an Overview
Five to ten years ago selecting an evaporative cooling system for a tunnel-ventilated poultry house was fairly simple. The decision was easy because a producer only had two real choices. He could spend about $1,000 dollars for a low pressure fogging system that produced five to eight degrees of cooling or $6,000 for a traditional evaporative cooling pad system that produced up to twenty degrees cooling. Though most producers wanted the twenty degrees cooling, they usually settled for the less costly five to eight degrees produced by a low pressure fogging system.
