High Speed Doors

High Speed doors open quickly, allowing less time to lose cooled or heated air; faster access to an area; and allowing less contamination and debris. Frequently Asked Questions What’s the fastest high speed door American Door offers?
The Exterior High Speed Metal Doors (998/999) and the Interior High Speed Freezer and Cooler Door (997) both open at up to 80 inches per second, the fastest in the line. What’s the difference between the fabric, rubber, and metal high speed door models?
The 998/999 use dual-walled aluminum or aluminum-and-polycarbonate panels for the highest wind resistance (up to +100/-100 PSF); the 995 uses 5 layers of NBR rubber for extreme-duty exterior use; and the 992/993/994 use 2-3 layers of PVC-coated polyester fabric for lighter exterior and interior openings. Is there a high speed door designed for freezers and coolers?
Yes. The Interior High Speed Freezer and Cooler Door (997) uses a curtain panel with conductive and radiant insulation layers, plus power for a guide heater and blower to help keep the track from icing. What happens if a forklift or vehicle hits a high speed door?
The strutted and rubber exterior models (992–995) are designed to break away from their side guides on impact to minimize damage, then self-reset and self-repair. What safety features come standard on high speed doors?
Infrared obstruction detection sensors, a wireless monitored reversing safety edge, and a NEMA 4X cULus-listed variable frequency drive control panel with onboard self-diagnostics, on every model. How are high speed doors activated?
Push button, key switch, pull switch, motion detector, radio control, loop detector, or treadle switch, depending on the model and how the opening is used.
