Arc evaporator

GPA started out as a plant manufacturer at the beginning of the 1990s. Our expertise in PVD coatings therefore stems from machine technology. The reliable arc evaporator technology developed by company founder Jürgen Lohmann has been used successfully worldwide ever since.

Introbild Arc-Verdampfer

PVD arc evaporator unit (cathodic arc source)

  • Robust all-rounders in industrial production
  • Flexible application options in research & development
  • Retrofit of older vacuum and coating systems
  • Supplementing existing systems with additional technology


  • Design and production Made in Germany
  • Improved economic efficiency due to cathode utilization > 70 % with higher evaporation rate
  • Quick cathode change thanks to quick-change system with clamping ring
  • High production reliability thanks to indirect water cooling
  • Cathode contact surface made of high-strength, thermally conductive copper alloy
  • For all known cathode materials (e.g. titanium, chromium, zirconium and alloys such as titanium aluminum, chromium aluminum)
