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.

Choosing the Right Frequency for Your Ultrasonic Cleaning Application

March 21, 2016

Choosing the Right Frequency for Your Ultrasonic Cleaning Application

The cleaning action of industrial ultrasonic cleaning systems depends on the high-energy collapse of tiny cavitation bubbles formed by the sound waves in the cleaning liquid. When the bubbles collapse, they release a momentary burst of energy that removes impurities and contaminants from the surfaces of the parts to be cleaned. The higher the frequency, the less time bubbles have to grow between sound wave cycles of compression and the smaller the bubbles. Small bubbles are less energetic but, for a given power input, there will be more of them. As a result, high frequency ultrasonic cleaning with lots of tiny bubbles delivers finely distributed gentle cleaning while lower frequencies with fewer and larger bubbles give a more energetic coarser-grained cleaning action. Choosing the industrial ultrasonic cleaner with the right frequency is key to obtaining effective cleaning.

Cleaning Metal and Glass Parts

The low frequency end of Kaijo’s industrial ultrasonic cleaning systems ranges from 26 kHz to 38 kHz. Cleaning systems such as the Phenix III Turn Key system operate at these frequencies. They can remove tough surface contaminants but their high cleaning energies are not suitable for soft materials or delicate parts. Typical items that can be cleaned with these systems are machined parts, glass, jewelry, wires and medical equipment.

Higher Frequencies for Precise Cleaning

The Kaijo Phenix Legend operates at midrange frequencies from 78 kHz to 160 kHz and can clean less robust parts and materials successfully. The cleaning of hard disk drives, LCDs, solar cells and panels, aluminum parts, quartz transducers and ceramic parts are typical applications. As an accessory for the Phenix Legend products, Kaijo offers a water resonance system (WRS) that conditions the cleaning water to optimize bubble formation and improve cleaning performance.

Gentle Cleaning at High Frequencies

At 450 kHz to 950 kHz, cleaning is precise without the risk of damage to delicate components. The Quava series of industrial ultrasonic cleaners can clean parts made of soft materials and with intricate surfaces that require careful handling. Typical parts cleaned at these frequencies include semiconductors, electronic components, delicate medical instruments and LEDs.

The Quava Spot ultrasonic generator works with the Spot Shower and Mega-Tube Nozzles for directed cleaning of hard disk drive surfaces, flat panel display glass and semiconductor wafers.

Flexible Cleaning Options

For industries that have multiple cleaning applications, it remains important to perform cleaning tasks using industrial ultrasonic cleaners that operate at the appropriate frequency. Rather than requiring customers to purchase several products for different frequencies, Kaijo offers cleaning systems that can operate at the various frequencies that are needed.

As well as covering the mid-range frequencies, the Phenix Legend can also operate at 38 kHz to deliver the robust cleaning action of the lower frequency bands. The Quava Multi can cover either the 26 kHz to 130 kHz or the 38 kHz to 160 kHz ranges. The new generation all-purpose Quava can operate at ten different frequencies, ranging from 26 kHz to 950 kHz. With such broad flexibility, these cleaners can handle many kinds of cleaning applications in one unit. The broad spectrum of industrial ultrasonic cleaners offered by Kaijo ensures that it is possible to get the most effective cleaning solution at the right frequency no matter what the cleaning requirements.
