Everything under control …

with unique services


Our mechanical infinitely variable speed adjustment optimizes procedures and processes.

While maintaining optimum motor efficiency, our mechanical infinitely variable V-belt drives convert power potential into precisely the speed that is currently needed.

This increases the safety and cost-effectiveness of the machines and systems. Furthermore, it reduces energy consumption, which benefits the environment.


Any kind of mechanical and plant engineering, for instance:

  • Textile machines
  • Printing machines
  • Drills and milling machines
  • Mixers and agitators
  • Pumps
  • Climate-control systems
  • Ventilation systems
  • Belt conveyor systems
  • Compressors
  • Agricultural machines

    … and much more because dedicated engineers and technicians will always discover new areas of application.
