High Speed Roll-Up >>>
Ryterna provides the safest hight speed roll-up, self-repairable, totally sealed, flexible hight performance doors for food, pharmaceutical, industrial, freezer, cleanroom and sector`s specialized applications.
Detectors with the standard equipment:
A presence detector realised by means of an infrared photocell, installed at ± 20 mm of the axis of the curtain and detecting the presence of a pedestrian or a vehicle, immediately opens the door and keeps it open as long as the presence is detected. Position of the photocell: 300 mm from the floor.
Wireless Detector (WDD):
A wireless detection system consisting of a transmitter in the bottom bag of the door and a receiver in the control box. The system operates according to the "open loop" principle: when the sensor encounters an obstacle, the transmitter leaves the standby mode and sends a signal to the receiver that immediately opens the door. The operating mode "open loop" offers an extremely high life time to the lithium battery of the transmitter, as it only operates when the sensor
encounters an obstacle, otherwise, the transmitter remains inactive.
Material and available colors:
Door curtain in reinforced PVC (900 g/m²), very resistant and provided with lateral bearing strings (section 16 x 12,5 mm).
