Compact plasma integration as industry standard of the future

The piezobrush® PZ3-i cold plasma unit is designed for integration into new and existing production lines and is therefore compact, safe and efficient. It is particularly well suited for the pre-treatment of processes such as bonding, printing and laminating, thus ensuring process and product quality in equal measure. Due to its uniquely compact and robust design, the piezobrush® PZ3-i can be quickly and easily integrated into production lines as well as partially to fully automated systems. In addition, comprehensive process control is possible in automated production processes, ensuring traceability. The device is also intuitive to operate and can be maintained without tools.

Technical data piezobrush® PZ3-i

  • Electrical connection: 24 V DC
  • Power consumption: max. 18 W
  • Weight: 370 g
  • Design: Integration unit with gas connection
  • Plasma temperature: < 50 °C
  • Typical treatment speeds:
    • Finest cleaning: 1-15 mm/s
    • Bonding processes: 10-150 mm/s
    • Printing processes: 100-1500 mm/s
  • Typical treatment distance: 2 – 10 mm
  • Typical treatment width: 5 – 29 mm



With an average treatment width of 5 – 29 mm (CDA), the piezobrush® PZ3-i is very well suited for the pre-treatment of adhesive grooves or for marking printing on low-energy materials. However, with other process gases such as nitrogen, even treatment widths of up to 50 mm are possible. For many applications, however, even larger treatment widths are required. Thanks to the modular design, it is very easy to string together the individual units at any time, so that even larger treatment widths can be individually adapted to the application.


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-i plasma handheld device. The PDD technology used to generate the cold plasma in piezobrush® PZ3-i 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.


  • Ease of maintenance: module change without tools
  • Modularity: modules matched to the application and substrate material, multiple units can be connected in series
  • Communication and process safety: monitoring of whether module is in permissible operating point by plasma OK signal, extremely low temperature input on the materials (no thermal overtreatment of substrates possible), digital I/O signal, LED status display, optional: BUS communication available (module history can be read out)
  • Work safety: touch safety (no light barrier or mechanical enclosure required), generally no personal protective equipment (PPE) necessary, very low nitrogen oxides
  • Integration: power supply by low voltage (24 V), low weight enables low-cost robot units, easy to integrate, compact design (separability of module carrier and driver unit), also suitable for small installation space, easy to implement hardware interfaces
  • Environmental friendliness: energy efficiency (max. 18 W), very low consumption of process gases (10 l/min), very environmentally harmful processes such as chemical primer or flame treatment processes are replaced
  • Very good price-performance ratio: low operating costs, customer-friendly initial costs
  • Low-threshold process validation due to compatibility with handheld device: identical core components and performance class
