The functionality of ultrasonic cleaning units

But what exactly is ultrasonic sound?

Oscillations with frequencies above 18 kHz (18.000 oscillations per second) are known as ultrasonic sound waves. Those lead to the development of millions of little vacuum blebs in liquids, which create pressure surges while they implode. This process is known as cavitation. The lower the frequency during this process (for example: 20 kHz), the bigger the pressure blebs. Therefore our units work with a cleaning-intensive high frequency of 35 kHz. This is the best frequency for an intensive, gentle and also fast cleaning. For the creation of ultrasonic the HF-generator converts the net frequency into the units frequency and passes it to the oscillation-systems to create mechanical vibrations in the liquid.

But how exactly does ultrasonic cleaning work?

Four major components contribute to ultrasonic cleaning:
Ultrasonic: creation of vacuum blebs for dirt removal
Temperature: most contaminations can be removed much better under higher temperatures of the cleaning liquid
Chemicals: the cleaning liquids advance cavitation and remove dirt-particles
Time: the combination of chemicals and ultrasonic waves reduces the cleaning time in contrast to other cleaning methods by about 90%. It depends on the level of contamination, whether the cleaning time amounts to seconds or minutes

All four of the above components need to come into operation equally. An imbalance of those components leads to less effective cleaning.

Ultrasonic cleaning is the cleaning process, which complies with today's standards of quality, efficiency and environmental sustainability. Ultrasonic waves clean in very short time spans and beat manual methods by far. Simultaneously the cleaning is much more gentle, because mechanical damages like scratches are avoided by the process itself.
