SoundClean - ultrasonic solution to prevent soiling
Preventive cleaning without chemicals – efficient, retrofittable, durable.
SoundClean is an innovative ultrasonic system that prevents deposits, soiling and fouling on metallic surfaces from the outset. The system was developed by Multi Sonic GmbH and will be distributed by Stemotech for the Austrian market in future – as a supplement for heat exchangers, pipelines and other process-critical components.

SoundClean - Ultrasonic technology for clean systems and stable processes
Contamination and deposits are among the most common causes of efficiency losses and maintenance work in industrial processes. With SoundClean, Stemotech now offers a technology that solves these problems preventively – before they even arise.
The system is based on high-frequency mechanical vibrations in the ultrasonic range. These generate turbulence and acoustic cavitation in the medium, which prevents particles from sticking to metallic surfaces. The effect: heat exchangers, pipes or silo walls remain permanently clean, cleaning cycles are eliminated and the service life of the components increases significantly.
SoundClean can be easily integrated into existing systems – via welding adapters or prepared threaded holes. The system is controlled via a robust, remotely maintainable control cabinet with touch display. The system is also suitable for outdoor areas thanks to its high IP protection.
Whether heat exchanger, process pipe or silo outlet – SoundClean protects your system, increases operational reliability and reduces maintenance costs to a minimum.
