High-speed industrial doors

Ideal means for sealing of small and large door apertures and averting air exchange in the most varied premises, where active movement of transportation means and personnel occurs. Door opening and closing occurs automatically. Thanks to rapid operation (door opening and closing speed is between 0,75 to 1,2 m/sec), loss of heated or cooled air is brought to minimum. Doors are exclusively functional. They excellently protect from moisture, drafts, noise and dust. They can be installed both inside and outside of the premises. The doors excellently fit in the shop premises, where intensive movement of forklift trucks occurs. They are ideal for warehouse and commercial premises. They are fit for food enterprises, where separation of premises is needed under technological requirements. Permissible sizes of the automatic doors are: width up to 12 m, height up to 6 m.

Structurally high-speed automatic doors consist of frontal flexible leaf, special skeleton frame, drive unit and control of drive unit.

Frontal flexible leaf is made of wear-resistant polyester with the polyvinyl chloride (PVC) coating 0,8mm thick. The leafs have transparent flexible windows, as well as special longitudinal elastic elements, retained by the skeleton frame of the door.

The skeleton frame the flexible leaf is moving in, is made of 2mm thick galvanized steel.

Electric motor, which transfers rotational moment to the longitudinal axis, is the basis of the drive unit. Flexible leaf either winds to the axis or is gathered upward with the help of special flexible belts.

The control unit of drive realizes the following functions:

automatic operation of doors at door aperture opening;
tracking of interferences in the zone of door aperture with the help of photo cells;
time delay in the open state;
automatic operation of doors during closing.
