Lift Smoke Free

Smoke extraction for the lift shaft

Against this background of the topical energy discussion and the VDI 4707 in future, the new subject plays an important role for the construction of elevators. With the Lift-Smoke-Free system the opening of the smoke extraction shutter will be closed and operated demand oriented. The whole shaft is controlled by smoke detectors which control the smoke extraction opening and also circulate information about evacuation travel to the elevator control unit.
