<<< Retour           High Style, High Speed, High Security. All in One Door. With an opening speed of up to five feet per second, the Spiral door offers the speed you need for high-traffic situations. And with its rigid, aluminum-slat construction, it eliminates any need for a second, overnight security door. Not to mention that its crisp lines give it a stylish look that’s great for all kinds of commercial and institutional, as well as industrial applications. Plus, because anodized aluminum will not corrode, you can count on that look to last for many years under even the worst weather conditions. High Performance – With no metal-to-metal contact, the Spiral door’s advanced spiral technology offers quiet operation. It can open and close automatically by your choice of floor loop, photo eyes or motion detector, improving traffic flow and efficiency. And its variable speed AC Drive system with soft acceleration and braking smoothes out routine stops and starts, virtually eliminating the clunking gear engagements you associate with typical overhead door operation. Energy-Efficient, Weather-Tight – The Spiral door’s aluminum 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. SPECIFICATIONS: (Subject to change) Model: Rytec® Spiral® Standard Size: Up to 26 feet 3 inches wide by 22 feet 11 inches high.
