Telsonic: Compact generator for industrial ultrasonic cleaning
Telsonic has launched the DCG cleaning generator with frequencies of 25 or 40 kHz, which not only generates powerful ultrasonic energy for industrial cleaning applications, but can also be easily integrated into the automation network.
Ultrasonic cleaning is ideal in many industries for effective final cleaning, but also for intermediate cleaning before further processing of a wide variety of workpieces or parts, especially as no or few additives are required. Telsonic has now launched the DCG cleaning generator with frequencies of 25 or 40 kHz, which not only generates powerful ultrasonic energy for industrial cleaning applications, but can also be easily integrated into the automation network. It provides the higher-level control system with valuable process feedback, for example on performance monitoring, pulse and degassing operation and even error messages that make servicing easier. This increases process transparency and system availability. At approx. 164 mm high, 106 mm wide and just under 400 mm long, the cleaning generator is very compact and designed for use in harsh industrial environments. It can be used both as a stand-alone device and as a built-in device in the control cabinet and is compatible with the previous model on the process side. The tube resonator can remain in the cleaning cabin when it is replaced.
An ultrasonic cleaning system consists of a generator, a converter and a resonator. The generator and the converter (with piezo-ceramic) generate the ultrasound. Depending on the size of the cleaning booth, the 340 to 1180 mm long resonator (tubular transducer) distributes the ultrasound into the cleaning medium. Here, the introduced sound generates positive and negative pressure, creating cavitation. Cavitation refers to bubbles in the liquid that implode during the pressure phases and thus generate the cleaning effect on the workpieces. Like millions of tiny brushes, they remove impurities down to the pores, even on complex part geometries. The cleaning effect depends on the temperature in the medium, the pressure prevailing in the liquid, the concentration of the additives in the bath and the setting of the ultrasonic system (frequency, amplitude, power). Process transparency through feedback from the cleaning generator is therefore important for an effective process.
