Door design dampens noise

Rytec Corp.'s Spiral Door has an opening speed of 60 inches per second and its rollup design features no metal-to-metal contact for quiet operation. Spiral Door's aluminum slats have a rubber membrane covering the connecting hinges to contain heating and cooling energy and prevent air infiltration. The door's tight profile takes up little room at the sides and along the header. Spiral Door's next generation System 4 door controller has an intelligent processor and variable frequency drive to generate an energy-efficient speed curve for smooth motion, soft starting and stopping.
