Different surfaces must be activated with the appropriate accessories in each case to achieve a good result in the end. Depending on individual customer requirements, there are therefore different exchangeable modules that are suitable for both the piezobrush® PZ3 handheld plasma device and the compact piezobrush® PZ3-i integration solution. The device recognizes which module is currently being used and automatically adjusts the process parameters accordingly.

The PDD® technology used to generate the cold plasma of the piezobrush® product series is based on the discharge of high electric fields. Therefore, the electrical conductivity of the component to be treated, for example, is of decisive importance when selecting the modules. A total of five different modules are currently available: the Standard module, the Nearfield module, the Needle module, the Nearfield Needle module and the Multigas module.

The Module Needle is suitable for treating very small or hard-to-reach areas on non-conductive materials. It can be used to treat narrow grooves, bores or other cavities, as very fine processing is performed with the needle.
