WATTS
PER
GALLON:
In general, smaller parts, requiring more critical cleaning, require higher watts per gallon
to achieve the desired level of cleanliness. Most industrial ultrasonic cleaning systems
use watt density from 50 - 100 watts per gallon. However, there is what is known as "the
large tank phenomenon", which indicates that tanks over 50 gallons usually require only
about 20 watts per gallon. The only explanation available is a point of diminishing
returns with regard to ultrasonic power.
LOADING:
Loading of the part(s) to be cleaned must be considered, with regard to the shape and
density. A large dense mass will not allow internal surfaces to be thoroughly cleaned
(i.e., metal castings). A rule of thumb for loading is that the load by weight should be
less than the weight of half the water volume, i.e., in 5 gallons, approximately 40 lbs. of
water, the maximum work load should be less than 20 pounds. In some cases, it is
better to ultrasonically clean two smaller loads, rather than one larger load.
The above information is not meant to give all the details to utilize ultrasonic cleaning
techniques. This information is to help the process designer gain some insight into the
variables of industrial ultrasonic cleaning.
Other suggestions on proper optimization of the ultrasonic cleaning system.
•
Read and follow all instructions in this manual.
•
Follow all instructions on the chemical that is to be used in the ultrasonic cleaning
system.
•
Test the cleaning capabilities of the system after each change in liquid (dilution of
chemical ratio, adding chemical, changing of liquid).
•
Locate the ultrasonic cleaning system in a dry, dust free area. Dust and/ or water
particles may diminish/ damage the electronics of the generator.
•
Maintain a maintenance log to ensure proper care of the equipment.
•
Turn off the equipment after each use.
