Thanks to a modern frequency inverter control system, these doors present a "soft" start on opening, and a "soft" stop on closing. The consequence of this system is that even if the door is continually in operation, there is virtually no wearing and as a result, minimum maintenance is required.
Opening speeds of 900mm or 1000mm per second without frequency inverter result in improved traffic flow. The top air seal of these roll-fast doors reduces the gap between the building wall and Roll-Fast Door preventing energy loss.
With the Economy Roll-Fast Door, downtime is significantly reduced and repairs, when needed, are quick and easy.
The Roll-Fast Door is powered by a motor specifically designed for these doors. Many types of opening and closing controls are available to match your exact requirements.
Economy Roll-Fast Doors are normally produced for internal Opening sizes up to 4000 mm H x 3000 mm W. Larger internal applications are also available upon request.
