Fullwave(40KHz) for Cleaning Blind Holes

Under the same ultrasonic intensity, 40KHz ultrasonic wave can create more cavitation quantity, and do much better in penetration, than ultrasonic wave close to 20KHz. So 40KHz ultrasonic wave does well in cleaning stuffs with complex-shaped surface or blind holes. Especially, 40KHz ultrasonic wave causes much lower noise than ultrasonic waves close to 20KHz.

Semiwave(28KHz) for gross rinse of simple surfaces

SEMIWAVE mode is the semiwave mode of 40KHz ultrasonic wave, however, it can also be identified by an oscilloscope as 28KHz. Its penetration performance is not as good as 40KHz, but it does well in cleaning stuffs with simple-shaped surfaces. Especially, SEMIWAVE ultrasonic wave causes much lower noise than single-frequency 28KHz or 40KHz ultrasonic wave.

Heating Function to Remove Oil and Wax

Heating can decrease the adhesive strength of oil and wax to certain stuffs to be cleaned, make the cleaning solution much easiler to create cavitations under ultrasonic wave and strengthen cavitation so as to increase the cavitation level of cleaning solution, and then enhance the cleaning effect.

Note: the best cavitation temperature of water is 60 degrees celsius.

Degas Mode for removing ultrasonic fatigue

DEGAS mode is an intermittent cleaning mode to remove residual bubbles(no cavitation nucleus) which can increase the loss of ultrasonic transmission and decrease the blast strength of cavitations in the cleaning solution. So it is a cleaning mode for removing ultrasonic fatigue to improve cleaning effect.
