DESIGN
The top roll consists of a steel tube with welded end caps. The shafts are supported on both sides by bearings. The curtain is riveted to the top roll and sealed towards the wall. Anodised aluminium side frames on both sides of the curtain guide its upward and downward movement. Hinges allow to open the side frame for service. A cover of anodised aluminium protects the front of the top roll.

DOOR CURTAIN
The door curtain is made of extremely rigid, tear-resistant fabric. Tensile strength: 185 kN/m. The coated fabric seals against moisture and drafts. Standard colours are blue, orange and grey. A counterbalance is provided by tension springs. The tension spring system also ensures that the door curtain remains firm and taut regardless of high wind loads.
Wind bars are available as an option to improve the wind resistance of the door significantly. The wind bars can be fitted in front, behind or on both sides of the curtain. Additional space requirement depending on their location.

KNOCK-OUT CAPABILITY
Self repairing knock-out capability - SRD. The door can be fitted with an optional knock-out capability for sizes up to 5.5 x 5.5 m (max. 22 m2 door area).

DRIVE UNIT
3-phase asynchronous motor with worm gear and connector is mounted directly to the top roll. Drive position left- or right-hand side.

CONTROL SYSTEM
The door is fitted with an ACS 70 type frequency converter control system as standard. An ACS 50 type control system is available as an option.
