Electronic Tachometers

Though evaporative cooling pads and fogging nozzles are an important part of any tunnel ventilation system, it is important to keep in mind that it is in fact the fans that provide the majority of the cooling during hot weather. It is the air speed created by the tunnel fans that extracts heat from the birds, pulls trapped heat from between the birds, aids in litter drying, and last but not least, insures uniform air temperatures from end to end. Quite simply put, it is the air moving capacity o...f a house’s tunnel fans not the evaporative cooling system, that primarily determines a producer’s ability to cool his birds on a hot summer day.
