Details

• Space-saving design: Thanks to the heavy-duty chain drive, the EFA-SST® Efficient does not require weight compensation by means of springs, saving space and maintenance costs. The compact door case dimensions enable installation in many situations. The door leaf is highly insulated, making the system suitable for indoor and outdoor use (with canopy).
• Guaranteed longevity: The door leaf consists of individual laths connected by a hinge chain. Rollers attached to the hinge chain are guided through vertical and spiral-shaped door leaf guides, producing very low noise levels and minimal wear (virtually no wear on the door leaf itself), ensuring a long service life.
• Innovative safety: Certified according to DIN/TS 18194:2020 to Resistance Class 2 (RC 2) as part of the EFAPROTECT® Series. The automatic burglary-proof locking mechanism provides effective protection against unwanted access while maintaining operational workflows.
