  • The most frequently installed top-opening roller-winding system in the world! With just one drive unit, the top edge is lowered and is rolled at the bottom synchronously. This eliminates the risk of collision and makes the system easy to install.
  • Thanks to a special-purpose compensating mechanism, the GKT telescopic coupling, there is no tension on the sheeting so no readjustment is required.
  • Low-cost system thanks to simply installation and a good range of accessories.
  • With the TFD system, the central roller tube delivers greater stability to wind pressure and less soiling of the sheeting. Combination of various sheeting and net fabrics. A WRZ 10 end guide is needed.
  • Drive unit can be installed at the end of the system, or in the middle. This makes greater lengths possible, with less torsion on the roller tube.
  • With HWA manual drive or EWA power drive. EWA conversion is a simple matter.
  • Drives possible with 3-phase or single-phase power supply.
  • Fully automatic activation with LSR ventilation controller and wind/rain function. With automation and single format rolling from 2.70 m, it is advisable to use the central tube system to avoid wear.
