什么是隔热卷帘门?为什么在工业环境中广泛使用?
隔热卷帘门,中文俗称保温卷帘门,是一种集高速开关性能和隔热结构于一体的工业门系统。它专为对温度控制、能耗管理和生产节奏有严格要求的场景而设计。
与普通 PVC 快速门其门帘是一种复合结构,通常由多层材料组成,例如:...........:
外层为耐磨、耐刮、易清洁的高强度聚氯乙烯;
隔热芯层(如泡沫、EVA、XPS 等)或双层铝合金;
边缘有多条密封条,防止热交换。
这种产品尤其适用于食品冷链、电子制造、洁净室、温控仓库和制药厂等应用。

隔热卷帘门的核心技术优势
1.卓越的隔热性能
由于采用了这种设计,多层复合结构的导热系数≥0.4W/m²-K,有效防止了冷暖空气的交换,减轻了冷却系统的负荷。
2.快速开启/关闭,提高效率
与伺服系统和限位开关逻辑集成后,整扇门可在 1 秒内完全打开,满足高节奏物流、AGV 交通和其他自动化生产要求。
3.综合密封设计
外围轨道使用三元乙丙橡胶条,底部使用柔性气囊与门框紧密密封,顶部的卷闸门槽提供额外的密封,实现全区域气密隔离。
4.便于维护的模块化系统
The door curtain, drive system, control system, and sensors can be replaced individually, resulting in low operational failure rates, short maintenance times, and minimal disruption to the factory’s overall production schedule.

选择建议和维护技巧
遴选建议
Determine the door opening size, daily opening and closing frequency, and traffic type (people, forklifts, AGVs, etc.).
Determine the temperature range and humidity of the application area to decide whether a heating and defrosting system is required.
Pay attention to the thickness of the door curtain (usually ≥15 mm for thermal insulation) and the track sealing structure.
Select products with CE/ISO/FDA compliance certification to meet the requirements of food or pharmaceutical factories.
维护点
Check the wear and tear of the door curtain and the condition of the guide rail seal strip every month.
Test the sensitivity of the sensor device (photoelectric/radar) every quarter and calibrate it in a timely manner.
If used in a high-humidity environment, it is recommended to add a heating wire to prevent condensation and ice buildup on the guide rail.
It is recommended to check the parameter operating status and emergency stop feedback function of the control system every six months.
常见问题(简明版)
Q1: Can insulated roller doors be used in sub-zero environments?
✅ They can be used in cold storage facilities and, when equipped with a heating system, are suitable for areas below -20°C.
Q2: Which type of door provides better insulation compared to a sliding door?
✅ Sliding doors offer better static insulation, while insulated roller doors are more suitable for scenarios with frequent opening and closing, providing higher dynamic insulation efficiency.
Q3: Does it support remote control or access control integration?
✅ Supports PLC interface integration, including barcode scanners, radar, ground magnetic sensors, and AGV scheduling
