Motor Ampere of Cooling Tower

Take a look at the flowrate, Guvnor, and see whether it is much higher too. You might find that additional users have caused your flowrate to increase, with a correponding increase in motor amps.

Dear Friend,

You have to furnish more details such as Motor Capacity and Speed, Whether Capacitor is added, Fan duty required and actual Fan capacity for the Fan installed, Blade Angle recommended and actually kept, Draft required and developed etc.

Pl. check for the suppliers specs for actual and recommended.

Much higher ampere means higher load on motor, if there is no any electrical or other problem in motor. Higher load on motor can be due to:

- higher flow rate than rated.

- higher differential pressure than rated.

- lower ambient temp than rated.

- mechanical obstruction, rubbing at bearings or seals.

- higher electric power supply frequency(Hz).

If higher flow is the problem, adjusting to lower blade angle may help.
