DMF International has released the RL3000B rapid autoroll door, designed to protect against temperature, draught, dust and insects. It is a version of the existing RL3000 with simplified features.
The simplified control system requires three-phase and can be operated in a manual or auto mode, with adjustable hold-open-time. It can accept all regular forms of activation. It operates at 0.8m/sec in both the opening and closing cycles, and a safety PE sensor is standard. The flexible bottom rail allows it to be struck without causing damage and removes the danger of injury to personnel. The flexible bottom rail can also have an the autoreverse feature, retracting the door to the open position after a very gentle impact. The doors are custom manufactured to the required size and can accommodate sizes from small pedestrian openings up to large 5m x 5m openings.
