The cavitation phenomenon consists of formation and growth of millions of microscopic bubbles under a low pressure stage produced into the ultrasonic bath due to a high power transducer 40 kHz. These bubbles break in all directions and attack every surface in contact with water, erasing dirt, impurities and pollutants when contacting with the materials or pieces into the bath. This phenomenon allows cleaning all kind of pieces without need of disassembling, due to it is taking part in all surface in contact with the liquid. The heat allows accelerate this cleaning proccess.
