The device is composed of a bench made entirely of stainless steel AISI 304. The ultrasonic generator has a power consumption of 900W, maximum frequency 40KHz. The generator, which has commands transistorized automatic leveling of the ultrasonic system is composed of a series of transducers PZT / 9 of lead zirconate titanate. For heating the water of the washing tank is equipped with resistors having a power of 4600W, controlled by a thermostatic device which will automatically keep the water temperature constant. The filling and emptying of the tank ultrasonic is made by automatic controls located on the main control panel. The time ultrasonic cleaning cycle is selectable by the timer who, returning to stand by position, remove power from the transducer resulting in arrest of the ultrasonic generator. On the control panel, which is built in a box of stainless steel, are installed all the organs of control and the related light bulbs. The cupboard doors below includes inspection of piping and electrical circuits.
