High-speed spiral door EFA-SST® ISO-60.

60 millimetre thick, thermally separated EFA-THERM® insulation laths used as standard, guarantee even better thermal insulation than ever before. Specially developed details ensure excellent vertical and horizontal sealing of the EFA-SST® ISO-60: thermally separated aluminium profiles with low-wear seals provide vertical insulation towards the case. The horizontal space between the building connection and the door leaf is closed by an active lintel seal made of aluminium. For use with large temperature differences and/or high humidity, both seals can be optionally equipped with heating bands.

The EFA-SST® ISO-60 is used wherever constant cool temperatures have to be maintained, for example in the field of airline catering: to ensure consistent quality of the meals served, constant and precise cooling is necessary. Doors in particular represent a sensitive transition between two temperature zones here.
When closed, the double-walled and thermally separated insulating laths of the EFA-SST® ISO-60 with a double rubber seal provide the appropriate insulation. Due to the high fluctuation of goods, the doors used in airline catering have to complete a correspondingly large number of opening and closing procedures. It is especially here that the high speeds of the EFAFLEX high-speed doors prevent excessive temperature exchange.

As the world’s leading manufacturer of high-speed doors, it is our aspiration to also be pioneers in the field of safety: All EFAFLEX products meet the highest standards and protect both people and the goods as well as the door itself.
It is not only our industrial doors that impress with their state-of-the-art safety technology, but also the associated systems: EFA-SCAN®, for example, is the world’s first laser scanner for use on doors, which is a reliable pulse generator and safety system in one.
