Under the action of a signal emitted by the generator, the ultrasonic that is mounted on the stainless-steel tank creates an ultrasonic wave that propagates into the liquid. This wave creates alternate positive and negative pressure waves.

During the negative pressure phase,tiny bubbles appear in the liquid, this is the phenomenon called cavitation. During the pressure phases, the bubbles implode when they touch the surface of the immersed parts, thus releasing the energy that creates them. This mechanical energy increases the effectiveness of the chemical action of the cleaning solution.
