The EFA-SST ISO-60 combines spiral operation with 60 mm insulated laths for thermal efficiency, indoor/outdoor use, high opening speed up to 2.5 m/s, robust sealing, and RC2 safety certification options.
- The closing door for thermos-regulated zones: Optimised insulation for cooling rooms and other humidity-heavy environments.
- Indoor and outdoor versatility: Canopy-ready installation and highly insulated door leaf
- Opening speeds and closing speeds: Up to speed of 2.5 m/s opening, and 1.0 m/s closing for fast controlled access.
- Thick 60 mm door leaf: EFA-THERM insulation for superior thermal performance
- Operating cycles and sizes up to: 250,000 cycles per year and large standard sizes up to w = 6,000 mm x h = 6,000 mm.
Designed for thermo-regulated zones, the EFA-SST ISO-60 combines spiral mechanics with 60 mm insulated laths for excellent thermal performance. It operates indoors or outdoors (canopy-ready), opening in speeds of up to 2.5 m/s, and closing in speeds of up to 1.0 m/s, with robust cycles. High-end safety features and precise seals minimise temperature exchange, ensuring reliable cooling and energy efficiency.
- The latest in high speed door technology
- Saves energy, reduces noise & quiet operation
- Space saving & sustainable
- Rapid opening, up to 4 m/s
- Advanced security & remote monitoring
ISO Spiral Features
(EFA-SST ISO-60)- Perfect heat insulation – 60 mm thick EFA-THERM insulation laths, thermally separated aluminium profiles with low-wear seals, vertical insulation towards the case, active lintel seal between building and door leaf, heating bands available for seals in high-temperature differences or humidity.
- Constant refrigeration of food & perfect sealing – Double-walled, thermally separated insulating laths with a double rubber seal to minimise temperature exchange, designed for environments with large temperature differentials and frequent openings, such as airline catering.
- High-end safety technology – Emphasis on advanced safety within the EFAPROTECT family, combines reliable door operation with protective systems to safeguard people and goods, optional high-end safety enhancements like EFA-SCAN laser safety.
- Indoor/outdoor versatility – Highly insulated door leaf suitable for both indoor use and outdoor installation when paired with a canopy, compact spiral design supports installations in constrained spaces.
