Sectional doors

HELIX / S600 - Sectional insulated high speed door

Super fast and space-saving spiral door

Promstahl sets ambitious targets as regards thermal insulation, noise attenuation and prices. Our research and development department has designed an unprecedented high-speed sectional door, which offers exceptional thermal insulation properties - Promstahl Helix. Conventionally two doors are mounted in frequently used openings: a thermally insulated sectional door closed for the night and a high-speed door working during the day. New Promstahl Helix/S600 door is a combination of these two applications in one product. This investment will pay for itself immediately. S600 door is equipped with an identical drive system as Helix spiral door, but it is equipped with a standard guide. The door opens at 6-times higher speed than the sectional door and can be mounted in the lintel of only 600 mm. S600 door can be equipped with a drive with frequency converter, which increases the speed of the door opening from 1.1 m/s to 1.5 m/s, making the opening speed 9 times higher than that of a conventional sectional door. It is a "super-fast" door. The standard height of the door panel is 366 mm. S600 door can also be equipped with 488 mm high panels of both versions - ISO and ALU.

Speed

Spiral Helix door opens at 6 times higher speed than a similar sectional door and thus it is extremely suitable for passages of high traffic intensity. The door opens at the speed of 1.1 m/s – depending on the size. This provides significant energy savings.

Energy efficiency

When the thickness of the panel is 40 mm, U coefficient reaches 1.5 W/m2K (for ISO panel and door size of 5000 x 5000 mm). Moreover, whenever required, the door can be equipped with completely transparent ALU panels without divisions.

Space savings

With revolutionary innovations used in the spiral Helix door, such as a chain drive system or a spiral system, the door does not require a large area located deeper in the building. Helically wound segments minimize the risk of friction of the panels against each other, as they do not come into contact with each other. Helix door can be used in locations, where the the building structure prevents the installation of horizontal guides of a standard sectional door to the ceiling.

Durability

Due to the intelligent drive system that does not require use of balancing springs, Helix spiral door does not have to be maintained until 200 000 cycles are reached.
