PUSH-PULL TRANSDUCERS MODULAR BATCH CLEANING SYSTEM
Crest Ultrasonics, Trenton, N.J.
Crest Ultrasonic’s Push-Pull Transducers are en- capsulated transducers mounted on each end of titanium bars. All of the sound gets transmitted into the liquid, as the transducers are always placed in the bath. The Push Pulls can be easily removed and placed into another tank. If the liq- uid in the ultrasonic bath should accidentally drain out, the Push Pulls automatically stop. The cleaning performance is near perfect and the maintenance convenience is unmatched.
