Albany Door Systems rapid roll door

Albany Door Systems has released the Rapid Roll 3000 door, a high-speed door made of metal.

The door offers high speed and security. It is built from galvanised steel and aluminium and can withstand harsh environments. It claims speeds in excess of 2.5 m/s, smooth operation and a minium of noise.

The disc drive system allows each metal slat to be independent from the next, which means no more slat noise, scratches or damage caused by slats resting on each other when the door is rolled up. The slats are attached to a belt that moves them up onto the disc drive systems. A rubber seal is inserted between each slat making a weather seal for this door.

Because the slats are independent each slat can be changed without moving other slats or taking down the door. This procedure can be done with two screwdrivers and a rubber roller.

Safety features include a travelling photocell and a fixed photocell in the door line. The travelling photocell moves with and in front of the bottom beam - this ensures any obstruction to the door blade is seen before it comes into contact with it. The fixed photocell reacts to any object passing through the door opening when the door is coming down and immediately reverses the door blade to the open position.
