It minimizes temperature loss while ensuring smooth logistics flow through extremely fast opening/closing speeds and excellent thermal insulation performance. It addresses the issue of temperature loss at doorway openings in fields such as cold chain logistics, food processing, constant temperature warehouses, and precision manufacturing.
I. Excellent Thermal Insulation, Significantly Reduces Energy Consumption
Working Principle: The door curtain adopts a split-type insulation structure: the inner and outer layers are made of high-strength polyester fabric, and the middle is filled with a thickened polyurethane insulation layer, forming an effective thermal barrier.
Customer Value: Greatly reduces the loss of cool or heat, directly lowering the operational load and energy consumption of refrigeration or heating equipment. The energy-saving effect is significant, offering a high return on investment.
II. High-Speed Passage, Improves Operational Efficiency
Working Principle: Utilizes a high-frequency servo control system, achieving opening speeds of 1.0-1.2 meters/second, enabling rapid opening and closing, significantly reducing the time the doorway remains open.
Customer Value:
Reduces Waiting Time: Accelerates the passage speed of vehicles and personnel, enhancing overall logistics efficiency.
Locks in Temperature: The extremely short opening time means less indoor-outdoor air exchange, better maintaining internal temperature stability.
III. Sturdy, Durable, Safe, and Reliable
Working Principle: The door structure is robust, with strong wind resistance (up to Class 7). Equipped with an infrared safety light curtain and a bottom safety sensing edge to ensure passage safety.
Customer Value: Capable of adapting to high-frequency use, providing long-term and reliable service, ensuring operational safety.
IV. Materials and Performance: Designed for Demanding Environments
The material selection and craftsmanship of our Insulated High-Speed Doors are designed to ensure stable operation in complex environments such as low temperatures and high humidity.
| Component | Primary Materials & Characteristics | Core Advantages |
| Door Curtain | Thickened double-layer polyester fabric + middle polyurethane foam insulation layer. Total thickness can reach 40mm-60mm. | Excellent thermal insulation performance (low thermal conductivity), lightweight, tear-resistant, resistant to deformation. |
| Guide Rail System | High-strength galvanized steel guide rails, paired with double-sided brush seals. | Smooth operation, good sealing, effectively reduces thermal bridging and heat exchange. |
| Drive System | High-performance servo motor, integrated with frequency control technology. | Smooth start/stop, precise control, low noise. Soft start/soft stop protects the mechanical structure. |
| Safety System | Infrared safety light curtains (both sides of the curtain), bottom pressure-sensitive safety edge. | Monitors obstacles in real-time; stops or reverses immediately upon obstruction, ensuring safety for people and vehicles. |
| Sealing System | Overlapping seal between curtains, side brush seals, bottom elastic airbag seal. | Multiple sealing combinations effectively block air convection, enhancing overall thermal insulation and airtightness. |
