3.3 Function
The ultrasound bath uses cavitation triggered by low-frequency
ultrasound. Piezoelectric oscillating systems are located on the
underside of the oscillating tank. The ultrasound generates strong
pressure fluctuations in the sonication fluid. Cavitation bubbles are
formed at the pressure minima. At higher ambient pressure around
the bubbles, they collapse very quickly. This results in strong local
microcurrents on the surfaces of the objects being treated. This
removes dirt from the surface of the objects. Dirt particles are
removed and fresh sonication fluid flows in.
SONOREX ultrasound baths use SweepTec®, a technology in which
the ultrasonic frequency often fluctuates around the value of the
operating frequency. The optimal operating frequency depends on
the load, filling level, temperature and type of sonication fluid. The
