How Ultrasonics Works

History Of Ultrasonics...

1914-1918 - During the First World War underwater transducers were used based on the studies of whales and dolphins for sonic range finding and ultrasonic communication systems.

1930’s - RCA (Radio Corporation of America) discovers ultrasonic’s for cleaning by accident.  While using Freon to cool internal radio components they noticed wave action surrounding a crystal.

1950’s to Present - Ultrasonics for cleaning is further developed in Russia, lower kHz are found to be better for industrial cleaning & higher range kHz are found better for jewellery, medical instruments and the semiconductor industries.


Ultrasonics 101...

Electric energy must first be converted into mechanical energy through a generator and a transducer.  The generator sends electric power to the transducer, this energy causes the transducer to vibrate at a very specific pre determined frequency.  The vibrating transducer then relays this sound into an ultrasonic solution.  When these sound waves come into contact with something submersed in the solution a cavitation bubble is created.

These bubbles have an internal spinning vortex which when bombarded by more sound waves become very unstable and starts to deform and finally implode.  This implosion creates a shockwave or jetting effect that sees a tremendous release of energy.  It is this energy that blasts away the fouling on whatever is submerged.  This energy equates to approximately 10,000 PSI at 400 km/hr and temperatures of up to 5,000 degrees.

One of the more appealing things about ultrasonic's is that all this incredible energy is happening at a microscopic level and as such causes no damage to the submersed object but does an incredible job in cleaning it.  Typical operating temperatures of our tanks are 150 degrees Fahrenheit or 65 degrees Celsius.



Quick turnaround, batch cleaning (many items can be cleaned at the same time) and pore deep cleaning.
