Instruction Manual
Introduction
This specification describes an operator panel used to control the operation of a ultra-sonic
cleaning unit.
This cleaning unit consists of a small stainless steel tank, filled with cleaning liquid into which
items to be cleaned are immersed. The whole is caused to vibrate at 30KHz. Microscopic,
cavitation bubbles within the fluid implode and hammer out adhered "dirt" from items to be
cleaned.
The vibration process itself causes some heating of the tank fluid, but most units require the
application of additional heat for control at a given set temperature. The cleaning process is set
to run for a set time and then the unit is automatically switched off.
