The revolutionary Altum high power ultrasonic technology 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 a high amount of energy that removes the fouling from the surface.
Altum's patented and software-guided technology is based on tailored design and optimization of the ultrasonic cleaning operation. The technology is scalable for the cleaning demands of any real industrial structures, and its advantage is the optimal cleaning effect that can be applied on-site without stopping the production process.
Altum's solution is unique because it enables our customers to:
- Combine externally applied power ultrasound with the capability of focusing the sound at any point of the inner structure that needs cleaning.
- Clean the industrial equipment without the need to stop the production process.
- Get a drastic increase in production output, energy efficiency, and a decrease in chemical usage.
