SST SECURE – High Speed Security Door

Spiral door, type „EFA-SST®-Classic“, with electro-mechanical door drive unit for permanent industrial application

The door system consists of:

• Self-supporting lateral steel frames;
• Steel parts generally galvanized, and
• Spiral-shaped door guidance

The load is transmitted on both sides: For achieving this, a synchronised shaft will be installed. For the exact, smooth and low-noise guidance of the hinge straps, ball-bearing precision rolling units have to be used. A sufficiently dimensioned tension spring mechanism, ensuring the weight balancing of the door leaf according to the standard DIN EN 12604 and a manual opening of the door (e.g. in the case of a power failure) is installed in the door frames.

Door leaf made of double-walled, Aluminium laths, which are fixed onto hinge straps and moved vertically (i.e. up or down), surface as anodised aluminium.

This SPIRAL BODY is designed to guide the laths of the door leaf completely without contact and thus without wear and with best possible noise reduction. The DOOR is driven by a geared motor. The door positions are registered by electro-mechanic limit switches positioned in the frame.

The MICROPROCESSOR CONTROL is installed together with the integrated frequency converter in a separate Steel switch cabinet, protection type IP 65. Connection to 230V 50 Hz power supply required on-site.

The scope of delivery includes a DOOR LINE GRID (EFA-TLG®), TÜV certified and in the direct door closing line: The safety system is integrated completely protected into the lateral frames and generates a light grid of infrared beams up to a height of 2.5 metres. Obstructions are detected without contact; the automatic closing movement is stopped immediately.
