is carried out with the addition of ultrasonic energy created by means of transducers that convert electrical energy into acoustic energy and then into cavitation of the liquid.
Imploding bubbles are the driving force of ultrasonic cleaning, with temperatures that can reach 5500°C and internal pressure generating a jet of water with a speed of 400 Km/h when meeting a surface.
The cavity size is determined by the frequency. Low frequencies generate large cavities and high frequencies generate a greater number of small cavities.
Ultrasonic energy is most commonly applied to water base detergents for the removal of tightly adhering or fine particles from solid surfaces and cleaning of parts with complex shapes.
