Anergy instruments offers cooling tower manager, the only controller of its kind, to reduce cooling tower fan`s power consumption. Water cooling in cooling tower is dependent on ambient wet-bulb temperature, cooling of water to about 5ºc above wet-bulb is energy efficient, trying to cool any further consumes more energy. The cooling tower manager is a microprocessor-based device with solid state sensing. It calculates ambient wet-bulb temperature, compares it with sump-water temperature and decides the numbers of fans to be operated in multi-cell cooling tower or the speed of the fan in case of multi speed fan. It saves energy by operating the cooling tower fans in the zone of least power consumption.
