Rapid Opening and Closing: Opening speed 0.3–2.0 m/s, closing speed 0.3–1.2 m/s, some models support 0.8–1.6 m/s.
Composite Protection: Equipped with multiple functions such as windproof, dustproof, thermal insulation, cold retention, insect prevention, sound insulation, fire resistance, odor prevention, and light transmission.
High-Frequency Durability: Daily usage frequency can reach 800–1000 times, with a no-fault operating lifespan of up to 150,000 times/year.
Structure and Materials
Door Curtain Material: Made of PVC-coated polyester fabric base, thickness 0.8–2.0 mm, with properties such as corrosion resistance, salt resistance, UV resistance, and tear resistance.
Wind-Resistant Structure: Built-in aluminum or steel wind-resistant ribs/tubes, connected in sections to evenly distribute wind pressure, wind resistance level up to 7–10 (can withstand wind speeds of approximately 17.1 m/s).
Door Frame Material: Commonly uses cold-rolled steel plate (electrostatically sprayed), stainless steel, or industrial aluminum alloy (such as 6063 aluminum alloy).
Bottom Seal: Equipped with U-shaped PVC air-sealed cloth or rubber sealing strips, fitting uneven ground; double-layer brushes or rubber sealing strips on both sides of the frame to achieve a ten-thousand-level sealing standard.
Power and Control System
Drive System: Uses dedicated brake motors (e.g., German SEW, AEW, ABB), power 0.75–5.5 kW, protection class IP55, supporting 220V/380V power supply.
Control Core: Based on PLC (Omron, Siemens, Mitsubishi, etc.) + inverter (Yaskawa, Delta, Mitsubishi, etc.), supporting soft start, end cushioning, S-curve speed stepless adjustment.
Control Voltage: Safe 24V DC low-voltage control with grounding protection.
Safety and Intelligence
Active Safety:
Infrared Safety Light Curtain: Automatically stops or reverses when encountering obstacles;
Bottom Safety Airbag: Rebounds upon obstruction to prevent pinching injuries;
Warning Light/Sound Prompt: Emits alarms during operation.
Passive Safety: Equipped with anti-collision posts, manual crank (emergency during power outage), UPS backup power (optional).
Intelligent Control: Supports radar, geomagnetic, remote control, card swipe, fingerprint, facial recognition, license plate recognition, AB door interlock, and other opening methods.
