How Kaijo’s Water Resonance System Improves Performance of Ultrasonic Cleaning Systems

March 31, 2016

How Kaijo's Water Resonance System Improves Performance of Ultrasonic Cleaning SystemsThe effectiveness of Kaijo’s ultrasonic cleaning systems can be enhanced by utilizing the water treatment technology of the Water Resonance System (WRS). When used with Kaijo’s turnkey systems, the WRS conditions the water to improve bubble formation. As a result, cavitation is achieved throughout the tank instead of staying concentrated over the transducer. Ultrasonic cleaning systems using the WRS clean faster and more uniformly. The system also received the Acoustical Society of Japan – Engineering & Development Award for 2007.

With WRS water treatment technology, Kaijo’s standard ultrasonic cleaning systems remove impurities and contaminants more effectively. The technology is especially useful for cleaning hard disk drives as well as metal and glass parts. The system works by optimizing the production of nuclei to form evenly distributed bubbles and avoiding the formation of bubbles that can block the transmission of ultrasonic waves. When the sound waves are not blocked, they and the resulting bubbles spread throughout the cleaning container. The effective sound pressure with WRS is five times greater than with conventional models operating alone and the product lifetime is increased by a factor of three to ten times.

The Kaijo water resonance system is offered as an accessory to other Kaijo ultrasonic cleaning products such as the Phenix III, operating at 26 kHz and 38 kHz and available in 600 W and 1200 W models. The WRS units are inserted in the water circulating loop or water supply. With WRS, the cleaning action is more even, leading to less erosion. While the systems are otherwise self-contained, the shape and material of the cleaning bath and the cleaning objects may affect the resonance and the effective area of the WRS. Kaijo can help with additional details and information to ensure that the systems work as designed and perform to their optimal potential.

The Water Resonance Systems are available in two types and several models. The WRS type is a circulating design that is inserted in the water-circulating loop of the ultrasonic cleaning system. The different models can be connected to 200/230 V three phase or 100/115 V single phase, 50/60 Hz. The cleaning solution can be with hydrocarbons or with de-ionized water, and the temperature of the cleaning liquid can be 10 to 70 or 10 to 30 degrees C.

The WRS-F type system is for one-pass operation with de-ionized water and the WRS unit is inserted into the water supply. Models can handle 300, 1200 or 2400 liters per hour at 10 to 40 degrees C. A flow meter and leak detector are optional.

Using the Kaijo water resonance system with one of the company’s turnkey ultrasonic cleaning products is a good way to maximize the system’s cleaning action. The better distribution of the sound waves and the more even action of the bubbles help clean parts quickly and more completely. For specific configurations of tanks and parts to be cleaned, Kaijo can help select the best model. Overall, these state-of-the-art systems reduce water and chemical use and lower energy consumption while delivering unparalleled cleaning performance.
