The pass-door with low threshold was developed in order to enable convenient crossing and minimise the risk of tripping.

The pass-door has a standard width of 900 mm and offers extra space.



Operating and control systems




Automatic operation

Powerful electric motors provide maximum convenience. Available as an operator unit with 230 V motors, virtually maintenance-free gear and quick release for manual operation. It is possible to move the operator with an axle chain drive if little space is available at the side.

The Entrematic IDO7 operator is a combination of the Entrematic IDO7 mechanical unit and a door controller from the Entrematic C700 series.
The system is available in 3 versions, for doors weighing up to 400 kg, for doors weighing over 400 kg and as high-speed version for doors up to 250 kg.

Thanks to a built-in frequency converter, the IDO7 drive unit features a soft-start and soft-stopp as standard. The gentle acceleration and deceleration at the end positions reduces the erosion and the noise level of the door.

Manual operation

Normstahl Industrial Sectional Doors can be operated manually using a rope pull. The rope pull is connected directly to the door curtain.

A hand chain makes it easier to operate heavy doors. The gear wheel chain drive (transmission ratio 1:4), which is connected directly to the shaft, is set to 1" shafts. Suitable for doors with a max. weight of up to 250 kg.




Integrated chain hoist

Another great feature of the IDO7 is the possibility of an integrated chain hoist (ratio 1:3,5) for fast emergency opening/closing in case of power failure.


Convenient control

The Entrematic C700 door controller offers a range of control options, from simple push-button operations to opening and closing the door through to sophisticated technical automatic functions.

The controller design is based on modules. Security upgrades and other automatic functions are available. Additional functions, such as magnetic loops, photocells, radar, radio control and restricted door opening are easy to add.

The function of limited door opening is possible by simply pushing a button printing (as standard).
