Warehouses are scenarios featuring rapid inbound and outbound logistics, making them highly suitable for installing hard fast rolling shutter doors. These fast doors adopt a spiral turbine structure and are equipped with dedicated high-speed and high-frequency door operators, enabling smooth, high-speed and high-frequency operation of the door body. Integrated with a variety of safety protection devices, the doors are made of rigid aluminum alloy, boasting a wind resistance rating of up to Grade 11. With an input voltage of 200-240V and a maximum output power of 1.5KW-2.2KW, the doors operate at an upward and downward speed of 0.6-2.0m/s respectively, and the opening and closing speed can be adjusted as required.
