The SECTOR PLUS is Ditec’s advanced counterbalanced high-speed roll-up door. Compared to the SMART, the SECTOR’s counterweight allows greater movement speed, reduces wear of the gearmotor due to less load, and it gives the option of an emergency opening release handle as opposed to a crank.

The compact frame allows the SECTOR to be fitted in areas with limited head room, as the height of the canopy is just 290mm.

Different safety devices can be selected depending on who will be using the door. You can choose to add photocells, an electromechanical bottom edge, a self-testing safety rib with conductive rubber, or a full sequential light grid to protect the users of the door from impacts.

Furthermore, you can change the drive unit and control panel to the “INVERTERmotion” version, which allows an opening speed of up to an incredible 2 metres per second.

As with all of Ditec’s range of high-speed doors, various curtain colours and thicknesses can be specified, as well as different finishes for the frames.

The Ditec SECTOR PLUS is the ideal choice for a roll-up door where safety and reliability are paramount.



The counterweight allows the door to open and close fast. With the INVERTERmotion, speed can be differentiated and increased up to 1.5 m/s.


The high operating speed avoids the doors remaining open longer than needed. Thus, the working environment remains stable and energy can be saved.


Aluminum or steel bars reinforce the curtain against wind loads.



The self-testing, sensible bottom edge and the photocells detect possible obstacles and reopen the door when needed.


In case of emergency, a red handle can be turned to release the counterweight and open the door.



Sector Plus doors offer the possibility of a modular curtain, which allows for full transparency. Reinforcement bars ensure that the curtain is nicely stretched. The compact columns provide an elegant appearance.


Counterweights reduce the efforts required by the motor, resulting in a longer lifetime and less maintenance costs. The Ditec original ACS break-away system avoids further damage to the aluminum bottom bar and steel columns in case of crash. It features so-called safety shoes that can easily be replaced by a non-specialised engineer. With a modular curtain, damaged sections can easily be substituted, without changing the entire curtain.


The Ditec Sector Plus is a compact door, with built-in counterweights and motor. The self-supporting frame and the absence of a side-motor allows for installation in a corridor or any other limited space.
