Control devices

There are several good reasons to use speed control as an optimum type of control for fans:

     » such as energy savings,
     » noise reduction,
     » control characteristics,
     » start up performance,
     » service life, etc.

Since frequency converters are the most meaningful state-of-the-art solution for speed control, Piller has turned its attention to this system and can advice you regarding the optimum solution. So that you will get a tailor made solution for the respective usage as a one-stop system solution on economically viable terms.

Consequently, Piller can also carry out the necessary matching of the whole system, to guarantee low-vibration running over the necessary control range to ISO/DIS 14694 or >300 kW power to DIN ISO 10816 without resonance problems.

We can advice you about control concepts and supplies complete control devices for the most important types of controls for fans:

     » for throttle control, the throttle valves incl. the variable speed drive
     » for twist control,
     » the twist controller incl. the variable speed drive, whether pneumatic or electric,
     » for speed control, the right frequency converter for the respective task from the supply
        of a separate installation device to be fitted through to complete switching cabinet to the
        customer's specifications.

If you wish, we can also match the complete fan, motor and frequency converter system, to guarantee the required vibrational quality in accordance with ISO/DIS 14694 or DIN ISO 10816-3 over the required control range without the usual resonance-vibration problems.
