Features 67%Power Saved The highefficiency module applies a novel ultrasonic atomizing technology that is ableto focus the ultrasonic power. Thereby, it can enhance the efficiency oftransducer up to 200% (2/3 power saved) than the regular module. (N.B. Thereare many factors that influence the efficiency and fog output of transducer,such as resonance frequency, the driver/generator etc. For example, based on the self-resonance oscillator, with the same resonance frequency 2.5MHz and fogoutput 200ml/h, the required input power for regular module is about 30W, and isonly 10W for the high efficiency module. Longer Lifetime Due to the higherefficiency of transducers, the input power can be reasonably turned down forthe corresponding fog output applications. Consequently, the lifetime oftransducers are prolonged.
