R Series
High speed roll-up doors are extremely econo mical door systems for interiors. The EFAFLEX high-speed doors differ from other doors through their enormously high opening and closing speeds.
High-speed roll-up doors dampen noise, maintain temperature zones at a constant level, and avoid that drafts have a chance at your company!
All high-speed roll-up doors of the R series have a space-saving design due to the door opening. EFAFLEX high-speed roll-up doors are mostly maintenance-free, and different and individual designs are available.
Power for top performance
Select the high-speed roll-up door EFA-SRT® from two different drive systems. For highly frequented passageways, EFAFLEX recommends a high-speed drive with microprocessor control and frequency converter. For less-frequented ope nings a direct drive is the most reasonably priced alternative. Weight balance is effected through tension spring action (see
drawing). This pulls the door upwards if the appropriate hand lever is moved, e.g. in the event of a power failure. A long service life is attained thanks to the order-specific calculation of spring tension.
Always in good shape
Robust plastic ropes and tension springs in the side members of the door hold the door leaf under tension when opening and closing. Wind, overpressure, and heat or cold cannot affect the door leaf. It is always in shape and can be wound up and unwound without any
problems. The extraordinary heavy-duty curtains are fully transparent or deliverable in different colours.
Work-saving
An inductive sensor is located directly at the motor. It sends the exact position of the door leaf to the control. The lifting height is automatically determined by the number of motor revolutions. Setting of the frame is not necessary.
