The revolutionary Altum high power ultrasonic system combines traditional ultrasonic cleaning with advanced beamforming techniques to localize and effectively clean a pre-defined target point. On top of this, Altum’s system is the only one in the world that can be applied externally to any existing production environment without making any changes to the production equipment.
Ultrasonic cleaning uses cavitation/air bubbles induced by high frequency pressure to agitate a liquid. As the liquid is constantly “disturbed” by sound waves and microstreams are formed, the size of the air bubbles increase and just as its threshold is exceeded, the cavitation violently collapses. This collapse of the air bubble produces shockwaves with high forces onto the inner surface of the container holding the liquid and as such onto the fouling attached to that surface, thus detaching the substrate.

The Altum approach
Ultrasound generating piezoelectric transducers are attached to the outer surface of the liquid container and focused at a specific target point/area for controlled maximum cleaning effect. These transducers produce an electrically oscillating ultrasonic wave (i.e. compression waves) in the liquid inside the container. The decrease in acoustic pressure (sound wave minima) results in the disturbance of the liquid and formation of air bubbles/cavitation with fluctuating diameters. Just as the cavitation threshold exceeds, these bubbles collapse with high amount of energy that removes the fouling from the surface.
Altum’s patent pending technology is based on tailored design and optimization of this ultrasonic cleaning operation. The technology is scalable for the cleaning demands of any real industrial structures and its advantage is optimal cleaning effect that can be applied onsite and does not require stopping the production process.
We are the only in the world that:
- Combine externally applied power ultrasound with the capability of focusing the sound in any point of the inner structure that needs cleaning.
- Clean your production equipment so that you don’t need to stop production.
- Enable you to get a drastic increase in production output, energy efficiency and decrease in chemical usage.
