The difference between single frequency and multi frequency ultrasonic cleaner’s
firstly single frequency ultrasonic cleaners operate at a fix frequency for example on 40kHz, several Year’s ago there been only single frequency ultrasonic cleaner’s available. Thanks to the Research & Development Departments Multi Frequency ultrasonic cleaners has been invented.
If purchasing an ultrasonic cleaner, it is important to consider which material’s & contamination’s need to be removed. If different materials need to be cleaned a multi frequency ultrasonic can be helpful in case of cleanliness and cleaning times. If the contamination will always be the same and if for example the budget need to be considered then a single frequency ultrasonic cleaner might be able to handle the task.
How to select the right Frequency for the ultrasonic cleaning application ?
For hard Material’s /Surfaces it is recommended to use a lower Frequency. Why because as lower the frequency as stronger the ultrasonic. As higher the frequency as more gentle the ultrasonic, for example when cleaning sensitive part’s. However depending on the material’s & cycle time’s low frequency can as well damage surface’s. For example when the cleaning time will be too long.
Secondly What if we like to remove different contamination’s?
Then a investment in a multi frequency ultrasonic cleaner will be a good decision. A multi frequency ultrasonic cleaners can be used for pre-cleaning (low Frequency) to remove polishing paste and for fine cleaning (high frequency)or for sensitive part’s.
our Conclusion, multi Frequency ultrasonic cleaner are already when the tank reach a certain dimension is not more expensive then single, besides it bring a lot of benefits.
Our Multi Frequency ultrasonic cleaner’s from Elma are available in 2 Version’s. the most common Version is 25/45kHz multi frequency and the other Version is 37/130kHz for sensitive part’s.
