Frequency
The output frequency of the ultrasonic cleaning system has to be correct for the
application. The most common frequency today for the majority of applications is 40 kHz.
More than 98% of ultrasonic cleaning application should be done with a 40 kHz
ultrasonic cleaning system. There are a few occasions where higher frequencies should
be used because of the sensitivity of the items to be cleaned. This system also
incorporates sweep technology. The sweep ensures a more uniform cleaning throughout
the liquid volume.
Power
Most ultrasonic cleaning applications require a minimum of about 40 watts per gallon
(peak power). If you use anything less than this, you may not achieve the desired
results.
Time
You can't just do a quick dip for most ultrasonic cleaning applications. A place to start
your cleaning time test is usually about five (5) minutes. You can add additional time
or decrease the time after a few experiments to understand how tenacious the
contamination is on your items to be cleaned.
Temperature
The temperature for ultrasonic cleaning applications will vary. Optimal ultrasonic
cleaning temperature for most applications is between 120°F and 160° F.
Tank loading
Be careful not to overload the system and or the baskets. Many times you can achieve
better cleaning by cleaning two smaller loads rather than cleaning one large load. Don't
use a basket any heavier than is required to support the items to be cleaned. Baskets
should be made from round stock (rod) whenever possible, rather than flat stock that
would reflect the ultrasonic energy.
Flow
In many applications the use of a pump and filter system will extent the useful life of the
cleaning chemistry. The pump / filter system helps flow away the contamination that is
loosened by the ultrasonic cleaning action. The overflow weir provides for the removal of
contamination that floats and this will minimize the re-depositing of contamination on the
items being cleaned.
Rinsing may be necessary to remove the detergent and or residual contamination that is
loosened by the ultrasonic cleaning action.
