SEPPES's high speed spiral door adopts a double-layer aluminum alloy door panel, and the middle is filled with polyurethane foam as a thermal insulation layer. The overall thickness can reach 40mm, and it can also achieve a good sound insulation effect.

    The tension and torque balance system is used inside the high speed spiral door  to ensure the normal operation of the high speed spiral door , reducing the load of the motor, thereby increasing the service life of the high speed spiral door. With a silent transmission device - nylon pulley, the high speed spiral door can run more smoothly, and reduce the noise, and will not affect the daily work of the staff.

    The standard safety light curtain and wireless safety bottom edge greatly increase the safety of the high speed spiral door. When the door touches an object or person during the descending process, the door curtain will stop quickly and open in the opposite direction. It is also equipped with a power failure release manual device, which can also be manually opened when the  high speed spiral door is powered off to achieve indoor and outdoor access.
