A Programmable Cooling Tower Controller controls the Fan Motor of a Cooling Tower, thereby saving Electrical Energy and Water. An Accurate PT 100 temperature sensor senses the temperature of the water in the tank below the cooling tower and switches the Fan Motor as per the user programmed Temperature. A user programmable dead band has been provided to prevent frequent switching ON/OFF of the Cooling Fan. The backlit LCD display shows the actual temperature of the tank water, the actual time of the day, the status of the Fan (ON or OFF) and the total  time the Cooling Fan has been ON/OFF uptill now. This Built- in Time totaliser helps the user to determine the energy saving that has been effected by employing the Cooling Tower Controller. The payback period of the unit is less than 2-3 months depending upon the Fan Motor rating and the Set Water tank temperature.
