Why does the ultrasound keep turning off during cleaning?

Those using the Disco-Antistat Ultrasonic 2.0 for the first time will immediately notice: The ultrasound doesn't run continuously but switches on and off repeatedly during the cleaning process.

Is this normal? Yes. This is exactly how it was designed.

Continuous operation is not always the best solution

Many assume that continuously operating ultrasound automatically cleans better. This seems logical at first – after all, more ultrasound should mean more cleaning power.

In practice, however, many more factors play a role.

Heat is generated during operation. If the ultrasound runs without interruption, the cleaning fluid gradually heats up. This is precisely what needs to be avoided when cleaning records.

Vinyl doesn't like high temperatures

Vinyl is a material that can be sensitive to heat. Even at temperatures around 35 °C, the risk of the material deforming increases. Therefore, the cleaning fluid should not heat up unnecessarily during the washing process.

For this reason, the Disco-Antistat Ultrasonic 2.0 deliberately operates in interval mode. The ultrasound is switched on and off regularly so that the temperature of the cleaning fluid remains controlled.

Developed for a balanced cleaning result

Numerous test series were carried out during development. The goal was not to let the ultrasound run as long as possible, but to develop a cleaning system that reliably removes dirt while protecting the vinyl.

The interval operation is therefore not a compromise, but part of the overall concept.
