Cleaning in ultrasonic mode

pulse
is a special feature which intensifies the ultrasonic
cleaning effect. This is particularly useful for the removal of
tenacious contaminations.
In addition, it takes less time for the unit to be ready for
operation after an exchange of the cleaning liquid or when a
new basket has been inserted (the unit is ready for operation
when the cavitation threshold is reached so that the ultrasonic
effect within the cleaning liquid is greatest). This shortens the
overall cleaning period.
There are certain operating phases with a reduced ultrasonic
cleaning effect due to physical reasons.
In particular when the cleaning liquid has been exchanged or
when a new basket with cleaning items has been inserted the
cleaning effect is temporarily reduced. An efficient ultrasonic
cleaning cannot be guaranteed during these phases.
The
pulse
mode keeps these phases to a minimum, which
leads to an optimum usability even with high throughput rates.

can be switched on or off as required during
operation.
Cleaning items with sensitive surfaces may be adversely
affected by a combination of
pulse
and 25 kHz. Please treat
sensitive items at 25 kHz plus
pulse
for short periods only.
Also, the sound-giving surface of the cleaning tank is subject to
a higher degree of cavitational erosion.

Cleaning in ultrasonic mode
dynamic
The
dynamic
function ensures more efficient ultrasonic cleaning
power. The constant switch between the sweep and pulse
functions
provides both even power distribution and
amplification.
In addition, it takes less time for the unit to be ready for
operation after an exchange of the cleaning liquid or when a
new basket has been inserted (when the cavitation threshold is
reached). This shortens the overall cleaning period.
There are certain operating phases with a reduced ultrasonic
cleaning effect due to physical reasons.
In particular when the cleaning liquid has been exchanged or
when a new basket with cleaning items has been inserted the
cleaning effect is temporarily reduced. An efficient ultrasonic
cleaning cannot be guaranteed during these phases.
The
dynamic
function switches off automatically after 10 min.
