Accessories
Stainless steel cover
To be used to cover the ultrasonic tray. It is also useful if you start the heating cycle of the washing
liquid. As a matter of fact, in order to reach the set washing temperature both efficiently and quickly,
it is recommended to cover the tray with the cover.
Be very careful
with the condensation that is
generated
as a result of the heating steam on the inside of the cover, because when opening, some liquid and
condensation may pour into electrical parts such as the power outlet. It is therefore necessary to lift
the cover vertically, so as to allow the condensation to drip only into the ultrasonic tray.
Rectangular stainless steel net rack
The stainless steel rack is a very useful accessory as it allows to optimise the washing of objects and
to then drain them into the tray.
Glasses
Special glasses complete with adjustable black rubber support ring are available. They are used to
save detergent liquid if you want to clean a small number of items, or if you want to wash with a
detergent solution in a glass while simultaneously rinsing in the other glass. They also serve to wash
objects with particularly aggressive solutions that can't not go directly into the steel tray.
Stainless steel support glass holder
.
The stainless steel support glass holder is used to support the glasses during washing. Remember to
adjust the glass support ring so that the bottom of the glass is always in contact with the liquid in the
tray, but at the same time does not come in contact with the bottom of the steel tray.

Washing with ultrasonic
Ultrasonic: what is it?
Ultrasonic is vibrations of a material medium similar to acoustic waves, but with frequencies that are
too high to be heard by the human ear. The human hearing frequency limit varies from about 10 kHz
to about 18 kHz. The audible frequency limit decreases with age. Specifically, the LINDA ultrasonic
cleaners work at a frequency of 39 kHz, in other words a frequency far beyond that audible.
The LINDA ultrasonic tanks are made up of an ultrasonic generator and two or three piezoelectric
transducers (depending on the model) that are placed on the external bottom of a stainless steel tray
containing the washing liquid. The electronic generator produces a continuous signal at the frequency
of 39 kHz and drives the piezoelectric transducers that transform the electrical signal into a
mechanical vibration. This vibrational energy is transmitted to the tray liquid at a frequency of 39,000
oscillations per second. These pressure and depression oscillations create an enormous quantity of
microbubbles inside the liquid that, by imploding in rapid succession, create immense impact energy
between the cleaning fluid and the surface to be cleaned. This is called "cavitation" and enables an
efficient and safe cleaning system with reduction in time.
