High Security, High Speed, with Architectural Style – All in One Door.With an opening speed of up to 60 inches per second, the Spiral® door offers the speed you need for high-traffic situations. Rigid, aluminum slat construction eliminates any need for a second overnight security door.
Crisp lines give the Spiral door a stylish look that’s great for all kinds of commercial, institutional, as well as industrial applications. Because its anodized aluminum will not corrode, you can count on that look to last for many years under even the worst weather conditions.
High-SecurityRigid, aluminum slat construction and optional, integral locking system provides unparalleled security.
FastOpens at up to 60 inches per second for improved traffic flow.
Whisper QuietThe unique Spiral roll-up design features no metal-to-metal contact, therefore offering whisper-quiet operation.
High PerformanceThe variable speed AC Drive system with soft acceleration and braking smooths out routine stops and starts, virtually eliminating the clunking gear engagements you associate with typical overhead door operation.
Energy Efficient and Tight SealAluminum slats, along with a durable rubber membrane which covers their aluminum connecting hinges, provide a 100% seal against dust pollution, drafts, and inclement weather. Optional insulation simply adds to the energy savings.
System 4™ Door Controller (Standard)Incorporating state-of-the-art motion control technology, the System 4 controller combines the flexibility and performance of AC Drive technology with the ease and precision of digital control.
ACTIVATORSThe System 4 door controller is designed to operate with many different types of activators, depending on the application and operating environment.
Floor Induction Loop (Optional)Activation loops embedded into the concrete on both sides of the doorway substantially reduce operator error in opening and closing doors. With no moving or exposed parts, floor induction loops are extremely reliable.
Motion Detectors (Optional)Motion detectors operate on microwave technology. They detect pedestrian and vehicle motion in a prescribed area. The detector sends a signal to the controller to open the door.
Presence Sensors (Optional)Presence sensors detect pedestrians and vehicles in the area of the detector. Motion is not necessary. The sensor signals the controller to open the door.
Radio Controls (Optional)A radio control consists of a transmitter and a receiver. The vehicle operator activates the transmitter which sends a signal to the receiver. The receiver then signals the controller to open the door.
Push Button (Optional)The push button is generally used with pedestrian traffic and is typically mounted on the wall near the door. Pedestrians push the button as they approach the door, which signals the door to open.
Pull Cords (Optional)The pull cords are switches mounted on the ceiling. Pedestrians and vehicle operators pull the cord as they approach the door, signaling the controller to open the door. Vehicle operators generally have to slow down to pull the cord.
Multiple Activators (Optional)The System 4 door controller permits many activators to be used in multiple combinations. For example, a door can be opened by forklifts through induction floor loops and by pedestrians through a push button, each with independent closing times to allow for pedestrians passing through the door.
Door Panel OptionsOptional insulation and clear polycarbonate windows available.
Side Frame OptionsOptional stainless steel package available.
Electrical Control OptionsSystem 4 controller has programmable inputs and outputs to accommodate special control applications without additional electrical components.
AirlocksIn airlock applications, one controller with various activators permits doors to be interconnected so only one door is open at a time.
Powder CoatingOptional powder coating to RAL standard colors.
