Cooling Tower Fan Controller & Pump Controller

 

THE COOLING TOWER ENERGY SAVER HELPS YOU SAVE ON YOUR ELECTRICITY BILLS TO THE TUNE OF UPTO 60% WITH A PAYBACK PERIOD OF JUST 30-45 DAYS

 

A sensor based controller that automatically switches the FAN motor situated on top of the Cooling Tower ON/OFF, with respect to the temperature of the water. This temperature is sensed with a 2’ ft. (minimum) 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 forced Fan Cooling (Induced Draft). The water in the cooling tower is made to flow with a lot of resistance (thru fiber packs / fills). During that flow the Fan motor sucks the heat over thereby cooling the water to maximum of 1-2 degrees below the external ambient temperature. After the water has cooled to this temperature, the Fan Motor continues to run uselessly, as further cooling of water is not possible. It is at this point the Cooling Tower Energy Saver stops the Fan motor and restarts only after the temperature of water has increased.

 

HOW THE SAVINGS ARE EFFECTED ?

 

The FAN Motor runs for the required time only. The unnecessary running of FAN Motor is thus avoided, thereby saving a lot of ENERGY / POWER & WATER. This results in recurring savings for your company, without affecting the cooling efficiency.

This savings are to the tune of up to 60% whereby you recover the cost of the energy saver in just 30 – 45 days !!!! These savings particularly increased during Night Shifts, Winter Season, when the load on Cooling Tower is less, etc. In Industrial environment our customers have clocked up to 70% of Electricity savings. Please refer the savings chart, for the POWER SAVED WITH ENERGY SAVER.
