Ultrasonic cleaning
Today, cleaning by ultrasound is the most modern fine cleaning
method.
The electric high-frequency energy created by an ultrasonic
generator is transformed into mechanical energy by piezo-
electrical transducer systems and is then transmitted into the
bath.
This process creates millions of tiny vacuum bubbles which
implode due to the variations of pressure caused by the
ultrasonic activity. Highly energetic liquid jets are created which
remove dirt particles from surfaces and even from the smallest
grooves and bores.

Interesting facts on cleaning by ultrasound
Basically, the cleaning result depends on four factors:
Ultrasonic energy is probably the most important mechanical
factor in the cleaning process. This energy must be transmitted
through a liquid medium to the surfaces which are to be
cleaned.
The present unit is fitted with the innovative sweep function
device: electronic oscillation of the sound field (sweep function)
prevents the formation of zones of low performance in the
ultrasonic bath.
For saponification and removal of the dirt particles a suitable
cleaning agent is required. We have a large range of cleaning
media on offer.
In addition, the use of cleaning media is required to reduce the
surface tension of the liquid. This increases the efficiency of the
ultrasonic activity considerably.
The effect of the cleaning medium is improved by the optimised
temperature of the cleaning liquid.
The cleaning period depends on the degree and the kind of
contamination, the cleaning agent used, the set temperature
and the cleaning process.
