How cleaning is carried out

Ultra-Sounds are sounds emitted at a frequency above the threshold of human hearing.

C.E.I.A. Ultrasonic Cleaners wash at ultra-sound frequencies. CEIA's Ultrasonic Cleaners carry out cleaning at an ultrasonic frequency which depends on the bath-transducer structure and on the dimensions of the bath, on the quantity and temperature of the cleaning liquid and on the detergent used.

Ultrasonic waves propagated in the liquid in the bath cause high- and low-pressure states in the liquid.

In the low-pressure phase, millions of tiny bubbles are formed in the liquid. This is called cavitation, that is to say the formation of cavities.

In the following high-pressure phase, the bubbles implode, letting loose large amounts of energy. These implosions act like a small army of brushes: they work in all directions, removing the dirt from every surface, including any recesses or openings in the objects being washed, even if these objects are of complex shapes.

Ultrasonic cleaning is very effective in cleaning hard materials, but less effective on soft or porous materials. The harder the surface, the more effective the ultrasonic cleaning action. Given that metals, glass, ceramics and rigid plastics are good conductors of sound, they are consequently ideal materials for ultrasonic cleaning.
