Deep Freeze Spiral Features
(EFA-SST TK-100)- Perfect heat insulation – 100 mm thick EFA-THERM insulation laths, thermally separated aluminium profiles with low-wear seals, vertical insulation toward the case, active lintel seal between building and door leaf, heating bands available for seals in high temperature differences or humidity.
- Energy-efficient frost protection – Contact surface heaters integrated in surrounding sealing profiles and the contact strip, heat the seals to reduce frost and heating costs, U-value up to 0.62 W/m2K, suitable for temperatures from +30°C to -30°C
- Dynamic door closure and sealing – Circumferential profile seal and dynamic door leaf guide (EFA-AFM) move the leaf toward the case when closing, enabling near-hermetic closure, installation level is on the warm side to minimise cold related wear.
- High-end safety technology – Built to high safety standards with advanced systems such as the world-class laser safety technologies (EFA-SCAN) ensuring reliable protection for people and goods.
- Size, range and durability – Standard sizes up to w= 4,500 mm x h= 6,000 mm, designed for up to 200,000 operating cycles per year, robust construction suitable for deep-freeze applications and demanding environments.
