SS Tray and tank - Imported, Non rustic (Ultrasonic Grade), Dynamic PEIZO Tranceuders (with high velocity focussing head)ultrasonic cleaners operate at 3040KHZ frequency. These high frequency sound waves convert the electrical energy in to ultrasonic wave in the from of vibration by means of PEIZO transducers. The accumulation of ultrasonic waves produces millions of microscopic cavitation bubbles. These cavitation bubbles drives the cleaning solution in to the components to be cleaned, removing away, all the dirt and accumulated residues on them.
