SAYO ultrasonic high-tech Kitchen Sink uses cutting-edge American technology of sound frequency conversion that cleans fruits, vegetables, seafood etc. of harmful chemicals, pesticides, dust and other surface impurities including pathogens, bacteria etc on the surface of the product. The sink is certified by TUV-SUD, a world leader in testing and product certification. Ultrasonic transducers fitted underneath the sink convert electrical energy to mechanical energy and vibrate in a vibrational frequency of 30,000 to40,000 Hz per second, generating energy waves in water. This creates millions of microscopic air cavities loaded with vacuum energy in water that creates blast energy equivalent of several hundred degrees of heat and thousands of atmospheres It results in quick separation of pesticides residues, carbons, chemicals, wax, germs, dust articles and other harmful pathogens from the surface.
