The KJM8 hard high-speed door features 45mm thick aluminum alloy panels with imported polyurethane foam filling (density ≥45kg/m³), providing excellent thermal insulation and fire resistance. The surface is anodized and organically colored for enhanced durability and aesthetic appeal. Multi-layer sealing strips at guides, panel joints, top, and bottom ensure comprehensive airtightness, while the load-bearing hinge design prevents panel contact and maintains flatness over millions of cycles. Available in multiple lifting configurations including turbine suction, elliptical suction, vertical lift, and 90° curved track to suit diverse site conditions.
Equipped with infrared photoelectric safety sensors at both sides of the frame and a bottom safety edge, the door instantly reverses upon detecting obstructions – even in blind spots – effectively protecting personnel and equipment. The servo/asynchronous motor drive system (0.75kW–3.5kW) with frequency converter and PLC controller delivers infinitely adjustable speed from 0.6m/s to 1.6m/s. Supports multiple control options including radar induction, ground loop, manual pull cord, remote control, push button, and card access. Withstands extreme temperatures from -35°C to +70°C, ensuring reliable operation in harsh environments.
Width and height are fully customizable to accommodate any access opening, with minimum area pricing starting from 9m². Designed to withstand wind loads up to National Standard Grade 12, the door structure ensures stability under extreme weather. The advanced sealing system minimizes air leakage at guides, panel joints, top, and bottom edges, effectively reducing energy loss. Ideal for manufacturing plants, logistics hubs, and cold storage facilities – our hard high-speed doors provide a secure, dustproof, and temperature-stable access solution for high-frequency industrial operations.
Airbag Bottom Edge: Inflatable safety edge detects obstacles and immediately reverses the door direction.
Photocell Sensors: Infrared beams at both sides detect objects in the door path and prevent closing.
Light Curtain: Full-width infrared light curtain provides comprehensive detection across the entire door opening.
Emergency Stop: Prominent E-stop button immediately halts all door movement for emergency situations.
Fast operation and thermal insulation maintain temperature zones in distribution centers.
Heavy-duty construction withstands high-frequency use in production facilities.
High-speed operation minimizes cold air loss in freezer and refrigerated areas.
Rapid opening and closing accelerate loading operations and reduce energy waste.
