A High-Intensity Industrial Ultrasound Company
Commercia-Scale High-Intensity Ultrasound
ISM is a high-intensity industrial ultrasound company. High-intensity (high amplitude) ultrasound is still mainly thought of as a laboratory technique, incapable of being efficiently implemented in commercial production. The reason for this reputation is that in order for most ultrasound-assisted processes to be efficient, it is necessary to generate ultrasonic amplitudes of at least 70 - 100 microns. Several ultrasound companies offer laboratory processors able to produce such amplitudes. However, these companies' industrial ultrasonic processors cannot generate amplitudes greater than about 25 microns, irrespective of the specified system power, which can be quite high for some companies. The difference between ultrasonic cavitation generated at the amplitudes of 30 and 100 microns is substantial, as shown in the video on the left.
One analogy of a high-power, low-amplitude approach would be trying to cook eggs in a very large pot, in which the water can only be warmed, but not boiled (analogy of low amplitude). The total power deposition into the process of warming a lot of water can be very high, but the desired effect will not be achieved. The proper procedure for designing an industrial egg boiling process would be to maximize the amount of water and eggs in the pot, but only under the condition that the boiling temperture of water can actually be reached (analogy of high amplitude).
The fact that conventional ultrasonic technology does not permit increasing ultrasonic processor sizes to the industrial scale without drastically lowering ultrasonic amplitudes is the reason why scale-up has always led to unavoidable reduction of cavitation intensities and significant losses in product quality.
ISM's ultrasonic processors are free from this limitation. With the use of our patented Barbell Horn Ultrasonic Technology (BHUT), we are able to generate extremely high ultrasonic cavitation intensities at any scale, directly implementing laboratory accomplishments in a production environment.
