Contaminants: When you’re cleaning

Contaminants: When you’re cleaning oils, water-based coolants and light dirt from parts, a unit with side-mounted or bottom-mounted transducers should be adequate, since oil floats and minimal dirt will settle on the bottom of the tank. That said, side-mounted transducers attack the part in different directions; cleaners that only have bottom-mounted transducers may suffer in performance due to dirt and contaminants settling on the transducers themselves. This does not occur with side-mounted transducers.. Also, agitation enhances the cleaning action of an ultrasonic cleaning machine, moving the parts through the cavitation.For heavily soiled items, it’s best to choose a unit with side-mounted transducers, since the large volume of dirt, carbon and grime that falls to the bottom of the tank during cleaning could sit atop transducers in a bottom-mounted unit and distort the sound wave, thus limiting the cleaning power
