Industrial Ultrasonic Cleaning Tanks, Immersibles, and Generators
The Ultrasonic Cleaning Process
Ultrasonic energy introduces high and low pressure phases
into a cleaning solution, which creates small vacuum bubbles
throughout the solution. Once these bubble reach a critical
size, they violently implode creating an intense scrubbing action. This process is known as ultrasonic cavitation. These
bubbles are microscopic in size and scrub the complex surfaces of a part to be cleaned.

Ultrasonic Frequencies
Cavitation can occur at any ultrasonic frequency, but each transducer is specifically tuned to operate at a set frequency. Crest
offers trandsucerized cleaning systems at 25 kHz, 40 kHz, 58
kHz, 132 kHz, 192 kHz, 470 kHz and 1000 kHz as well as custom combinations including 25/40 kHz and 58/192 kHz.

To create ultrasonics energy, piezoelectric transducers are
bonded to the tank. An ultrasonic generator takes line voltage
and coverts it to a high frequency pulse that is applied to the
transducers. The crystals in the transducers expand and contract with these electrical pulses creating acoustical energy in
the solution. It is this acoustical energy that creates the pressure changes leading to ultrasonic cavitation.

Choosing Your Frequency:
• Lower frequencies produce larger cavitation bubbles with
stronger implosions for heavy duty cleaning.
• Higher frequencies produce smaller cavitation bubbles with
milder implosions for more delicate cleaning or for submicron particulate removal.

Industrial Ultrasonic Tanks
Cleaning Process Development
Crest offers a very liberal demo tank loaner program as well as
three full-service application labs to help you develop a cleaning
process that includes the correct ultrasonic frequency, chemistry, and cleaning procedures.

Tanks are constructed of cavitation resistant, bright annealed
316L stainless steel providing the optimum environment for
precision cleaning with extended service life. Tanks are welded
inside and out to insure a long life and sturdy performance.
Transducerized tanks are a plug-and-play solution for a number of cleaning needs.

Ultrasonic Immersible Transducers
Immersibles are also constructed of cavitation resistant, bright
annealed 316L stainless steel with robotically welded seams
to insure a long life. Immersible transducers are a perfect way
to introduce ultrasonic energy into existing tanks. Also, the
units are easily replaceable for economical repairs.

Ultrasonic Generators
Both Genesis and MW ultrasonic generators have a history of
outstanding performance in wattages from 250 to 2000 watts.
They have the ability to monitor watt output to insure consistent cleaning time after time. Only Crest offers TRU-SWEEP™
sweep frequency, which eliminates inconsistent cleaning by
sweeping a +/- 1kHz around the center frequency at a set
repetitive rate.
