The first and the only new generation technology which provides saving by controlling the motor. It applies to asynchronous electric motors running with 1 and 3-phase constant speed. Ecowat device decreases energy consumption by making asynchronous electrical motors, used in the constant-speed implementations, more efficient.Ecowat is not; Invertor, Dimmer, Frequency convertor or frequency invertor, Thyristor compensation aided by capacitor.
