Springless sectional doors achieve high cycle rates while keeping maintenance costs low. Since there are no torsion springs to maintain or replace, they are a popular solution for areas where doors need to be opened and closed very frequently.
Do you require a safe operator solution for your springless sectional door? If so, find out more about our MDF series now! Our direct-mount operators offer a TÜV-certified, integrated, and maintenance-free safety catch. What this means for you: You do not need to take any additional mechanical safety precautions when installing your sectional door operator!
Operators from the MDF series are available in various sizes, as well as in a HD version for springless sectional doors with particularly high cycle rates:
To select the optimal operator solution, the diameter of the winding shaft in mm and the weight of the door curtain in kg are required. We would be happy to advise you!

How is our MDF Operator Controlled?
Use our CS 320 comfortable control unit for controlling roller shutters. It is available with or without a frequency converter, depending on your requirements.To the Industrial Door Control Units
Custom versions, such as additional voltages and frequencies, different output speeds, higher protection classes (e.g. ATEX version for facilities where gas and dust are processed) and hollow shaft diameters, are possible. Feel free to contact us!
Operating manuals for our operator systems and products on safety instructions, installation, commissioning, operation, and maintenance can be found in our search for installation manuals.
