piezobrush® PZ3

Effective plasma handheld device for manual use

piezobrush® PZ3 mit Modulen

Piezobrush® PZ3 has been designed as a compact plasma handheld device for use in laboratories, predevelopment and assembly of small series. With a maximum power consumption of 18 W, the Piezoelectric Direct Discharge (PDD®) technology is used to generate cold active plasma at a temperature of less than 50°C. The heart of this portable plasma device is the TDK piezo plasma generator CeraPlas™ – a high-voltage discharge device for generating cold atmospheric-pressure plasma. Plasma is used to increase the surface energy of many materials with high efficiency, as well as to reduce germs and odors.

Modules

Different surfaces have to be activated with the appropriate accessories to achieve an ideal result. Currently two different modules are available for the piezobrush® PZ3 plasma handheld device. The PDD technology used to generate the cold plasma in piezobrush® PZ3 is based on the discharge of high electric fields. Therefore, the electrical conductivity of the component to be treated is of decisive importance when choosing the modules.

Module Standard

piezobrush® PZ3 Module Standard for the treatment of non-conductive surfaces

This module is designed for the surface treatment of non-conductive substrates such as plastics, ceramics or glass. For effective treatment, a module-to-substrate distance of 1 to 5 mm is recommended. If uncontrolled arcing occurs on the substrate during use, the device switches off automatically. In this case the surface is at least partially conductive and should therefore be treated with the module Nearfield.

Module Nearfield

piezobrush® PZ3 Module Nearfield for the treatment of conductive surfaces

This module is used to treat (partially) electrically conductive materials such as metals, CFRP, indium tin oxide or conductive plastics. However, this module may also be necessary for the ideal treatment of materials with conductive coatings or assemblies with conductive components. With this module, the plasma only ignites when it is close enough to a conductive surface (this may also be hidden under a thin insulating layer). At a distance of a few millimeters, a violet glow is visible in the gap between module and substrate indicating that the treatment is being performed.

The device automatically detects which module is currently in the device and automatically adjusts the parameters accordingly.

Display

For process control of plasma treatment, the piezobrush® PZ3 is equipped with various features that can be selected and modified via the display.

  • Process control
    ◊ Stopwatch: For monitoring the treatment time
    ◊ Countdown: Time setting with automatic switch-off function
    ◊ Metronome: Acoustic feedback after defined treatment time
  • Power adjustment: Reduction of plasma power in several increments

Technology – Plasma handheld with Piezo Technology

In order to provide products having convincingly compact dimensions, we developed the PDD® Technology. PDD stands for piezoelectric Direct Discharge. It is based on the direct, electric discharge at an openly operated piezoelectric transformer (PT).

piezobrush® PZ3 in transport case

By means of PDD® Technology, low input voltage is transformed. This results in high electric field strengths. The ambient process gas – typically air – is dissociated and ionized.

The advantages of direct discharge control are obvious: The excitation of gas molecules is highly efficient and safe. Furthermore, the power density of the compact device is extremely high. In practice, a processing performance level is now achieved that had previously been possible only by means of considerably larger installations. This is the ideal device for manual applications in laboratories, medical technology, in commerce and in industry.

The piezobrush® has been conceived for application by end-users. Here, relyon plasma has paid particular attention to usability and user-friendliness. The piezobrush® requires no specialist, technical knowledge and no complex infrastructure.

The CeraPlas F plasma generator, from TDK Electronics, is a direct high-voltage discharge component for plasma generation, forms the heart of the plasma handheld. The piezoelectric RF plasma generator offers a high ionization rate and an effective ozone generation rate as well as multigas ignition, low power consumption and no magnetic fields.

piezobrush® PZ3 as loan unit

Would you like to test the piezobrush® PZ3 plasma handheld? No problem – our piezobrush® PZ3 is also available on loan. We will send you the piezobrush® PZ3 for a rental fee and you can test the tool directly on your premises in your individual working environment.
