Immersion cleaning

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.

The selection of the correct equipment and cleaning liquid is difficult because it varies with each cleaning application and depends on the parts being cleaned and contaminants to be removed.

Ultrasonic cleaning can be done in simple stainless steel tanks with transducers bonded to the underside, but, in industrial machines, transducers are encased for immersion within the liquid and specific features are adopted to improve the performances and efficiency.
