Ultrasonic machine technology
A high frequency generator produces approx. 35,000 oscillations per
second which are transmitted to the cleaning fluid and cause it to resonate.
The energy density of the sonic field is so high that cavitation takes place.
Countless small vacuum bubbles are created and collapse within
microseconds as a result of pressure and suction: they implode. The pulses
thus released remove contamination even from the deepest, inaccessible
points, or lead to homogenisation, dispersion and degassing.
The compact housing and the vibratory trough consist of stainless steel.
The cleaning/contact fluid can be easily and safely drained off through the
discharge ball valve located on the housing.
In conjunction with the spray water protected design of the unit, this
provides a maximum of operational reliability.
Below the vibratory trough, there is the powerful HF generator with a
continuous peak power of 2x 240 or 2x 600 watts. The wide beam
vibration system with PZT oscillators act on the cleaning fluid evenly, thus
achieving an excellent cleaning effect.
Accessories
Lid in stainless steel for type UR 1
1 litre TICKOPUR RW 77 cleaning agent
Perforated basket in stainless steel for type UR 1
Perforated basket in stainless steel for type UR 2
Cleaning the machine
The mains plug is to be disconnected before each cleaning operation.
Thoroughly rinse the machine’s stainless steel trough from time to time
and rub it dry.
If strips of dirt remain on the stainless steel surface of the vibratory
trough after a long period of use, these can be removed with a standard
commercial steel cleaner without scouring additives.
!
Do not clean the ultrasonic machines with running water or immerse
them in a sink.
Risk of fatal electric shocks
Only use a cloth moistened with water.
Do not use steel wool, scrapers or other abrasive tools.
The vibratory trough can otherwise be damaged.
