• What types of high-speed doors are suitable for cleanrooms and controlled environments?

  High-speed PVC roll-up doors and zipper high-speed doors are commonly used in cleanrooms and controlled environments. Their fast operation helps reduce air exchange, dust, and particle intrusion, while maintaining stable room pressure and cleanliness. Airtightness is especially important for cleanroom applications. The narrow frame design and precise connection between the door curtain, guides, and sealing strips directly affect sealing performance. Broadup has obtained SGS-tested airtightness certification for ISO Class 6 cleanroom applications, demonstrating reliable sealing performance for demanding controlled environments. Stainless steel frames, touchless activation, and additional safety systems are also available according to hygiene level, room pressure, and operating requirements.

• Are thermal-insulated high-speed doors available?

  Yes. We offer thermal-insulated high-speed door solutions for cold storage, food processing, refrigerated logistics, and other temperature-controlled environments. Insulated curtains or panels, combined with fast opening and closing, help reduce air exchange, temperature loss, and energy consumption. The appropriate insulation solution can be selected according to the operating temperature and application requirements.

• What makes our insulated door curtain different?

  Our insulated curtain uses double-layer aluminum foil bubble insulation with an overlapping structure, ensuring continuous insulation coverage throughout the entire curtain and minimizing thermal weak points. The aluminum foil insulation is also water-resistant, so even if the outer PVC fabric is accidentally damaged, the internal insulation layer will not easily absorb large amounts of moisture, helping maintain stable thermal performance and durability.

• Is the PVC material of a high-speed door fireproof?

  No. Standard PVC curtain material is not considered fireproof. Flame-retardant PVC options are available for certain applications to help reduce flame spread and improve safety. However, a flame-retardant high-speed door should not be considered a certified fire-rated door. Please contact us if your project has specific fire-resistance or flame-retardancy requirements.

• What activation methods are available for high-speed doors?

  High-speed doors can be activated by push buttons (standard), pull-cord switches, induction loops, pedestrian/vehicle detection radar, and touchless switches. Different methods can be selected or combined according to site requirements.

• What emergency opening and safety options are available?

  Safety and emergency options include photoelectric sensors (standard), safety light curtains, safety edge/airbag sensors, UPS backup power, manual chain hoist systems, and emergency pull switches. These options help improve safety and allow emergency operation during power failure or abnormal conditions.

• What voltage options are available for high-speed doors?

  Our standard power supply is 220V three-phase. Depending on local electrical standards and project requirements, we can also customize 110V or 380V systems in single-phase or three-phase configurations. Please provide your required voltage, phase, and frequency when requesting a quotation.

• What types of motors are available for high-speed doors?

  High-speed doors can be equipped with different industrial-grade motors and drive systems, including SEW motors, SEJ, Servo systems, and other reliable brands depending on the door model and project requirements. The motor is selected according to the door size, operating speed, frequency of use, power supply, and control system. Our team can recommend the appropriate drive solution to ensure smooth, reliable, and efficient operation.

• What is the maximum size of a high-speed door?

  High-speed doors can be customized in a wide range of sizes to meet different industrial applications. Depending on the door model, structural design, wind load, installation environment, and operating requirements, large high-speed doors can be manufactured up to approximately 12 m wide × 12 m high for certain applications. For larger openings, factors such as wind resistance, frame strength, curtain structure, operating frequency, and motor capacity must be carefully evaluated. Please provide the opening dimensions and site conditions, and our engineering team will recommend the most suitable door type and configuration for your project.

• How much space is required to install a high-speed door?

  Installation space varies depending on the door model, opening size, motor position, and site conditions, so there is no single standard clearance that applies to every project. Customers can provide the opening dimensions and surrounding site details, and our engineering team will recommend the most suitable configuration. For projects with very limited or challenging installation space, Broadup can also develop custom structural designs and special opening solutions to adapt the door to the actual site conditions.

• Can customers install the high-speed doors themselves?

  Yes. To make installation as simple and efficient as possible, most major components are pre-assembled and tested before shipment, which significantly reduces on-site assembly work and installation complexity.
