Standardised function blocks simplify the system start-up. Based on the experience of application engineers, the modules have been specially developed for the control, regulation and protection of axial and radial compressors and turbines. By adjusting just a few parameters, the complete Operation of compressors and turbines is possible.

  • Simplified engineering and system start-up
  • Less programming work, lower costs

The application manager will discuss with you in advance which functions are suitable for your equipment and where customised programming makes sense.
