ultrasonic cleaning machine The 22L ultrasonic cleaner is a microprocessor-controlled device that uses ultrasonic or high frequency sound waves to clean jewelry and other delicate items. Ultrasonic cleaning is based on the cavitation effect caused by high frequency ultrasonic wave vibration signals in fluid. Microscopic bubbles that expand and rapidly collapse cause cavitation, which creates an effective cleaning action on the surface of object being cleaned. Additionally, the bubbles are small enough to penetrate even microscopic crevices, cleaning them thoroughly and consistently. High efficiency saves cleaning solvent, thermal energy, work place and labor! It is utilization of digital program in ultrasonic cleaner to control the unit, according to the quantity and condition of the items to be cleaned to choose a working cycle time. As a result, it is more convenient and efficient than hand wash, steam cleaners, high pressure water jet cleaning or other machines. High-quality stainless steel wire drawing cleaning groove can avoid corrosion water stains and keep the groove brand new.
