SST-ISO-K High Speed Spiral Door

Rapid Insulation Door


With the development of fast acting insulation doors EFAFLEX is going in a completely new direction. Two door technologies have been combined in a single, innovative system solution : The SST-ISO-K is based on the multiple patented rapid spiral door. Equipped with a high insulation door panel from thermally separated slats, a K-factor of at least 0.5 W/m2K is achieved. The seals employed prevent unwanted air or temperature exchanges. The result is constant, climatic conditions. The SST-ISO-K is therefore the ideal closure door for very frequently used openings, e.g. in controlled temperature logistics, in refrigerated areas, or in conventional industrial constructions, if a demanding insulation is required. A high travel speed of up to 1.5 m/s and a practically wear free door panel qualify the SST-ISO-K as a professional single door solution. The construction is designed for at least 150,000 operations per year, the highest availability with the least maintenance expenditure is guaranteed.

Closing door for thermoregulated zones

Doors in cooled rooms must be able to withstand very high loads. Top quality and perfect workmanship are a prerequisite for all components to withstand cold and humidity. EFA-SST®-ISO-K is the ideal closing door when a sophisticated insulation is required for highly frequented openings, e.g. in cold-storage rooms.

Insulates perfectly, saves energy

The EFA-SST®-ISO-K combines two EFAFLEX door technologies to one innovative solution: the multi-patented spiral as well as highly insulating laths. In addition, cost-intensive sealing prevents the exchange of air and temperature. These components make up an excellently insulated door.

Perfection in detail

A better heat insulation then ever before is from now on guaranteed by the 60 mm thick EFA-THERM® insulation laths! The laths are thermally separated as a standard. Especially developed details provide excellent vertical and horizontal sealing of the EFA-SST®-ISO-K. The vertical insulation towards the frame is carried out by thermally separated aluminium profiles with nearly wear-free sealings. The horizontal space between wall and door leaf is closed by an active lintel sealing made of aluminium. For being used even in conditions of high temperature differences and/or high humidity, both sealings can optionally be equipped with heating tapes.

Constant temperatures

The EFA-SST®-ISO-K is used in situations where constantly low temperatures have to be maintained, e.g. in the field of airline catering. In order to ensure the constantly high quality of served meals, constant and exact cooling is necessary. Especially doors are a very sensitive point between two temperature zones.

Perfect sealing

If closed, the double-walled and thermally separated insulation lath of the EFA-SST®-ISO-K with a double rubber sealing provides the corresponding insulation. Due to the high fluctuation of goods, doors used in the field of airline catering must perform many loadings. Here, the high speeds of the EFAFLEX high-speed doors prevent an excessive temperature exchange.
