Safety curtains installed on high speed doors are designed to ensure the safety of the operator.
In addition to manufacturing their own range of rapid roll doors, DMF is an exclusive supplier of the German-engineered Efaflex high speed turbo doors.
Efaflex high speed doors are fast action doors operating at speeds up to 4m/sec.
Efaflex provides a TÜV-certified infrared light grid system, referred to as the TLG designed to avoid crashes in the lower area of the door, where nearly 90% of all crashes usually take place.
The self-monitoring safety curtains are directly installed into the lateral door tracks of the high speed door in a well-protected and inobtrusive way.
The infrared safety curtains monitor 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 an obstacle is detected, the closing movement is stopped immediately or not initiated at all, returning the door blade to the open position.
This unique door technology protects persons, doors, vehicles and materials, and is a critical addition to fast-moving doors.
