Energy efficient doorways
The energy efficient spiral door maximizes traffic flow, while minimizing energy loss through the doorway, particularly on exterior walls. If the doorway is used frequently as in many distribution or industrial operations, the high-speed doors can be more effective at saving energy than doors with heavily insulated panels.
The door’s high-speed operation minimizes air exchange and the roll up aluminum slats have a durable rubber membrane covering their connecting hinges to contain heating/cooling energy to prevent air infiltration. The intelligent processor and variable frequency drive of the door controller generate an energy-efficient speed curve for smooth motion, soft starting and soft stopping.
