Ultrasonic units can prioduce annoying sounds.
Wear personal ear protection devices when working close to an
ultrasonic unit which is operated without cover. This is
particularly recommendable for 25 kHz operation without cover.
Do not reach inside the cleaning liquid or touch sound-carrying
parts (tank, basket, cleaning items, etc.) during operation.
The manufacturer cannot be held liable for damages on
persons, equipment or cleaning items caused by improper use
and non-observance of the Operating Instructions.
The operator is responsible for the instruction of the operating
personnel.

3 Functioning
Today, cleaning by ultrasound is the latest fine cleaning
method.
The electric high-frequency energy created by an ultrasonic
generator is transformed into mechanical energy by
piezoelectrical 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.
These jets remove dirt particles fom surfaces and even from the
smallest grooves and bores.
Basically, the cleaning result is determined by four factors:
Ultrasonic energy is probably the most efficient mechanic factor
in the cleaning process. This energy must be transmitted
through a liquid medium to the surfaces which are to be
cleaned.
Transsonic TI-H units are fitted with the innovative sweep
technology: through electronic oscillation of the sound field
(sweeping) the zones of low performance in the ultrasonic bath
are reduced.
For saponification and removal of the dirt particles a suitable
cleaning chemical is required. Elma has a large range of
cleaning media on offer.
Cleaning chemicals are also necessary 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 optimum
temperature of the cleaning liquid.
The cleaning period depends on the degree and the kind of
contamination, on the cleaning chemical, on the temperature
and on the stage of the cleaning process.
