Product Description

Product Description

1. Sealing and Thermal Insulation Performance

• Cold Storage High-Speed Zipper Doors:
  • Utilize dual or triple-layer curtain designs with insulating materials (e.g., polyurethane or rock wool) between layers.
  • Feature zipper-closure tracks that form a complete seal with the door frame to minimize thermal exchange.
  • May include track heating systems to prevent ice formation between the curtain and track in subzero conditions.

2.Frost Resistance and De-Icing Mechanisms

• Cold Storage High-Speed Zipper Doors:
  • Dual-axis synchronized drive system: Enhances opening/closing speeds (up to 2 m/s) to reduce cold air loss.
  • Heated tracks: Built-in heating elements prevent freezing and ensure smooth operation in low temperatures.
  • Auto-realignment capability: Curtains automatically reposition if dislodged, minimizing downtime.

 

3.Material Durability

• Cold Storage High-Speed Zipper Doors:
  • Curtain materials: Low-temperature-resistant compounds (e.g., anti-static PVC, reinforced polyester fabric) rated for -50°C to +70°C.
  • Structural components: Galvanized steel or stainless steel tracks/hardware for corrosion resistance in high-humidity environments.

4. Safety and Functional Features

• Cold Storage High-Speed Zipper Doors:
  • Safety systems: Infrared sensors, flexible impact-resistant bottom edges, overload protection, and emergency power interfaces.
  • Hygienic compliance: Designed for cleanroom or food/pharmaceutical applications with smooth, washable surfaces.

Application Scenarios and Energy Efficiency

• Cold Storage High-Speed Zipper Doors:
  • Optimized for cold storage facilities, pharmaceutical plants, and food processing facilities.
  • Reduce cold air loss by over 80%, significantly lowering energy consumption for refrigeration systems
