When in use, select a suitable cooling medium, turn on the ultrasonic transmitter, and make the ultrasonic waves generated by the transducer pass through the horn to produce ultrasonic cavitation to play a role. The more preferred cooling medium is air cooling, liquid cooling or a combination of both.

The frequency of the ultrasonic transducer is 15-135KHz.

The power adjustable range of the ultrasonic transducer is 5-100%. The total power can be selected within the range of 75-1500w depending on the actual needs.
