1.2 FUNDAMENTALS OF ULTRASONIC
CLEANING
Ultrasonic energy is activated in a liquid by means of
transducers that convert electrical energy to acoustic
(sound) energy. Transducers are similar to radio speakers
in that they convert electrical energy to acoustic energy;
however; they differ in that they operate at ultrasonic
frequencies and transmit acoustic energy to a liquid rather
than to air.
When ultrasonic energy exists in a liquid it results in
alternative rarefactions and compressions of the liquid.
During rarefaction, small vacuum cavities are formed
which collapse (implode) during compression. This is a
continual and rapid process known as cavitation.
Cavitation produces a powerful scrubbing action. This
scrubbing action is what makes ultrasonic cleaning so
powerful and effective.
Three factors affect the scrubbing action:
1. Degassing is the removal of unwanted air from the
liquid.
As the cavities form, they fill with unwanted air bubbles
that resist collapse and tend to remain suspended in
the liquid. This is usually undesirable in ultrasonic
cleaning because the bubbles act as “shock
absorbers” and reduce the scrubbing effect.
It is possible to reduce unwanted air in the cleaning
solution by modulating the sound energy to permit
adjacent bubbles to coalesce, float to the surface, and
escape. This modulation must be matched to the
particular process and effects desired.
Crest ultrasonic cleaning systems exclusively feature
“Simultaneous Multi-frequency” and two modes of
gassing modulation, thus offering maximum versatility
in degassing.

Crest Ultrasonics Corp.
Manual #9907-103-OJSTD •Page 5
1.2 FUNDAMENTALS OF ULTRASONIC
CLEANING, continued
2. Electrical frequency affects cleaning efficiency by
determining the cavity size.
Low frequencies such as 25 kHz generate large, but
relatively few, cavities with high cleaning power. High
frequencies generate a great number of small cavities
with good penetrating capability. The selection of the
correct frequency varies with each cleaning
application.
Crest engineers have eliminated the difficulties
traditionally associated with the selection of proper
frequency ranges for ultrasonic cleaning through the
patented “Simultaneous Multi-frequency” design and
uniform energy distribution.
3. Chemical characteristics of the liquid at specific
temperatures also affect the cleaning process.
Many cleaning solutions are available for use with the
Crest ultrasonic cleaning console. In selecting the
proper cleaning solution for your application, you will
take many variables into consideration, including the
composition and construction of the components to be
cleaned and the nature of the particular
contaminant(s). It is important that you read carefully
the literature provided by the chemical manufacturer.
Line operators should be aware of the importance of
achieving and maintaining proper temperature for a
particular cleaning liquid, as improper temperatures
may have adverse effects on the cleaning process.
Crest Ultrasonics recommends that all selection and
use of cleaning chemicals be closely coordinated by a
designated Process Supervisor who is trained and
knowledgeable in the chemical and operational
aspects of ultrasonic cleaning.

1.2 FUNDAMENTALS OF ULTRASONIC
CLEANING, continued
To assist you in determining the proper chemistry and
equipment requirements for your different cleaning needs,
Crest Ultrasonics operates an APPLICATIONS
LABORATORY with a CLASS 100 CLEAN ROOM. To
contact the Laboratory, please call (609) 883-4000.
Four basic components are fundamental to every
ultrasonic cleaning system:
1. Generator - Crest’s GENESIS Plug-in Generator
Module is specifically designed to power ultrasonic
cleaning. Generator modules are mounted within the
internal compartment of the console.
Please see booklet IM-5310 in the REFERENCE
section of this manual for detailed information about
the GENESIS generator module.
2. Transducers - convert electrical energy into acoustic
(sound) energy. Usually they are mounted on the
bottom and/ or sides of each tank that employs
ultrasonics.
Crest’s exclusive VIBRA-BAR transducer design is
ideally engineered to provide the reliable, constant
compression levels that are essential to the success of
ultrasonic cleaning. See booklet IM-5310 in the
“Reference” section of this manual for details regarding
and use of VIBRA-BAR transducers.
3. Tank(s) - In the cleaning console, the processes of
washing, rinsing, and drying all take place within tanks
that may be conveniently situated in the most compact
unit possible, for the ultimate in convenience and
efficiency.
4. Cleaning Liquid - Effective cleaning depends upon
the careful selection of cleaning liquids, matched with
the correct levels of temperature, electrical frequency,
and ultrasonic modulations.
Even the most lengthy and sophisticated systems utilize
these basic building blocks for ultrasonic cleaning.
