Automatic temperature controller

Key Attributes.

A digital microprocessor based thermostatic controller that automatically switches the Cooling Tower FAN motor ON/OFF based on the set point of the cooling water supply at the water basin. The temperature is sensed using a 60 cm long sensor fitted onto the water tank, below the cooling tower. PRINCIPLE OF OPERATION OF COOLING TOWER ENERGY SAVER: A Cooling Tower works on the principle of evaporative cooling with air to water contact forced through an Induced draft Fan. The water in the cooling tower by SyGuru Innovators Pvt. Ltd, 820 Siddharth Complex, R.C. Dutt Road, Alkapuri, Vadodara-7; Tel:0265 2325024; The air is sucked through the cooling tower fills/splitters and mist eliminator over coming the resistance in the path using a induced draft Fan so that depending on the cooling tower design it brings the cooling water temperatures down depending on the ambient conditions and L/G ratio. Once the basic designed Approach (Temperature difference between ambient airs wet bulb and the cooled water Temperature) of cooling tower has reached, further cooling of water is not possible even if we run the fan and thus under such circumstances we could switch off the fan without compromising on the cooling efficiency to save energy. Many a times during the winter session or cooler nights or even when the system heat load are not enough for the cooling tower design, the Fan may be switched off as the hot water falling through the cooling tower will naturally reach the desired temperature. The purpose of cooling tower is to cool the hot water to a desired level and once such temperatures are achieved, we can switch off the fan saving in energy and maintenance cost in the system. This is what is automated using our microprocessor based cooling tower fan controller. It also has two on time and off time logger (optional) so that the actual off time of the fan can be logged daily to know the amount of energy saved
