Spiral door EFA-SST® N Therm

class 2industrialmotorized

Overview
The EFA-SST® N Therm combines modern spiral door technology with high thermal insulation for industrial and commercial buildings. It is designed for heated halls and workshops where energy efficiency, quiet operation and consistent performance are essential. Highly insulating EFA-THERM® slats reduce heat loss and—together with high airtightness—support efficient energy savings.

Details

• Reduced energy loss during operation: EFA-THERM® slats provide high thermal resistance to maintain stable internal temperatures and reduce heating costs.
• Quiet, trouble-free cycles: Modern spiral drive and guidance ensure smooth opening and closing to minimise downtime and disturbances in daily operations.
• Faster access times: Opening and closing speeds are at least twice those of conventional sectional doors, reducing unwanted air exchange and waiting times.
