Electric, high-speed drive.

  • Short opening and closing times reduce heat losses and substantially increase transit speed.
  • The system is available with pushbutton control and variable speed control and is suitable for remote operation.
  • This system can be used with door leaf areas of up to 25 m².

Electric, fully automatic operation (Impulse).

  • Drives with impulse operation are suitable for sectional doors which are operated very frequently.
  • During opening and closing, the door automatically moves to the appropriate end position.
  • When in the fully open position, the entire door opening is available.
  • An obstacle detection system (safety edge) is incorporated in the bottom seal of the door.
  • When the photocell beam of the safety edge system is broken by contact between the seal and an obstacle, the sectional door will stop and reverse.
  • This system is suitable for a door leaf area of up to 50 m².

Electric, semi-automatic operation (Dead man).

  • This is a good choice for sectional doors which are not operated very frequently.
  • The upward movement of the door is initiated by pressing and releasing a button.
  • The sectional door opens and stops when it reaches the upper end position.
  • The button for the downward movement has to be pushed and held down (dead man operation).
  • This type of operation is suitable for sectional doors of up to 50 m² door leaf area.
