How much ultrasonic power does your cleaning tank require?
The right amount of ultrasonic energy (usually expressed in watts/gallon) depends on the size of the cleaning bath and the difficulty of the cleaning requirement. Tanks in the one- to two-gallon range often provide up to 90 watts per gallon of ultrasonic power, plenty for most jobs, even cleaning out the ultra-fine passages of fuel injector nozzles.
"Achieving the same cleaning effect in larger tanks requires less energy density," Pedeflous noted. "Excellent cleaning has been demonstrated in tanks having 50 gallons capacity with only 25-30 watts per gallon. The more difficult the application, the greater energy density is required for effective cleaning."

On the other hand, too much ultrasonic power may result in cavitation erosion occurring on delicate or highly polished parts that are near the transducer-radiating surface. Cavitation is the formation and collapse of low-pressure bubbles that can pit the surface of metals. Aluminum, copper, brass and other soft metals are especially susceptible to cavitation erosion.
