DMF safety curtain for high speed doors

Rapid high speed doors are used in applications that are exposed to a high frequency of forklift or pedestrian traffic flows. Therefore, safety of the operator is extremely important.

DMF, manufactures their own rapid roll doors, and are the exclusive suppliers of the German engineered Efaflex high speed turbo doors.

The doors are a fast action type door, operating at up to 4 m/sec.

To avoid crashes in the lower area of the door, where nearly 90% of all crashes happen, Efaflex can provide a TÜV-certified infra red light grid system, referred to as the TLG. This system is unique worldwide and it is completely self-monitoring. The TLG unit is directly installed into the lateral door tracks of the high speed door, so that it is well protected and inobtrusive working by monitoring the closing plane of the door up to a height of 2.5 metres. Crossing infrared rays generate a nearly flat light grid which can detect even the smallest obstacles without contacting them. If there is something in the way, the closing movement is stopped immediately or not initiated at all, respectively, returning the door blade to the open position.

This unique door technology protects persons, doors, vehicles and material, and is critical addition to such fast moving doors.
