The most important things to consider in choosing an ultrasonic cleaning system are the size of the tank, the frequency of the system and the power it can provide. Aside from these the accessories such as a tank temperature heater and holding basket should also be considered when choosing the right system for a cleaning application.
Cleaning tank heater:
Ultrasonic cleaners work by generating tiny cavitation bubbles which clean and scrub surfaces of parts to remove contamination. However, when contaminants on surfaces are hard deposits that are difficult to clean, the cleaning action of the bubbles will take more time. In these cases using a heating, the liquid in the cleaning tank will help to soften or loosen the hardened contamination from the surfaces being cleaned. That’s where the cleaning tank heater enters the picture.
While cleaning tank heaters are a useful option for ultrasonic cleaning systems, they should be designed for the application. Untreated plain water (below 100 degrees centigrade) may be used most of the time but mild cleaning solutions can also be used. If the cleaning solution is considered, the heat settings should be controlled so that solution won’t start boiling. The ultrasonic transducer should also be designed in a way that it will be able to withstand high temperatures.
Using sweep frequencies:
Kaijo’s ultrasonic cleaning systems operate at certain frequencies and are designed to achieve the optimum cleaning results according to the size of the cavitation bubbles and their cleaning intensity. However, a system may experience some unpredictable negative effects. This results in the ultrasonic waves canceling each other and no cleaning occurs. Using sweep frequencies will reduce this effect.
Water resonance system
The water resonance system helps ensure even cleaning action throughout the tank. The water treatment of a water resonance system provides an even distribution of nuclei essential for bubble formation. This allows bubbles to form everywhere within the cleaning solution rather than mostly above the ultrasonic transducer. This provides an even cleaning action on everything placed in the cleaning tank.
