High Speed Zipper Door

Product Overview

The Industrial High-Speed Zipper Door utilizes an engineered track-zipper engagement system that locks the high-tenacity curtain securely into the side guides under dynamic wind loads. Designed for high-frequency industrial environments exceeding 2,000 operational cycles per day, the system features an automatic self-resetting mechanism: if the curtain is accidentally dislodged by a forklift impact, it reinserts into the track automatically during the subsequent opening cycle, eliminating manual intervention and reducing downtime.

Key Features

Self-Repairing Breakaway Track

Curtain unzips cleanly upon impact without structural deformation; automatically realigns and re-tracks on the next upward movement.

Positive Air Seal

Continuous zipper-to-track connection and dual brush seals restrict air infiltration, maintaining strict room differential pressure in cleanrooms and cold environments.

Closed-Loop Servo Drive System

Absolute encoder motor delivers programmable soft-start/stop profiles, eliminating mechanical shock and ensuring precise limit positioning over millions of cycles.

Certified Wind Load Resistance

Flexible PVC curtain paired with spring-loaded side guides absorbs wind pressure up to Class 6 (tested and certified per EN 12424 / DIN EN 12453).

High-Speed Operation

Variable frequency inverter drive enables adjustable opening speeds up to 2.5 m/s, reducing thermal loss and optimizing heavy logistics traffic.

Product Structure

The system is engineered with six core modular assemblies to ensure rapid installation and long-term mechanical stability:

Roll Cover & Housing Assembly

Material: Corrosion-resistant galvanized steel or optional AISI 304 stainless steel protective hood.

Drive Roll Tube

Component: Precision-balanced aluminum alloy tube ensuring smooth curtain winding without eccentricity.

High-Tenacity PVC Curtain

Component: Woven polyester fabric with high-density polyethylene zipper teeth welded along both vertical edges.

Side Guide Tracks

Component: Extruded aluminum vertical profiles equipped with low-friction UHMW-PE (Ultra-High-Molecular-Weight Polyethylene) guide liners.

Bottom Weather Bar

Component: Weighted aluminum extrusion profile housing the wireless safety edge sensor and rubber sealing skirt.

Electrical Control Enclosure

Component: IP55-rated PLC control box paired with an integrated high-performance servo inverter.

Applications

Automotive Manufacturing: Stamping shops, paint transfer zones, and high-traffic internal partitioning.

Cold Storage & Distribution: Freezers, blast chillers, and loading docks requiring rapid thermal isolation.

Pharmaceutical & Cleanrooms: ISO Class 5 to 8 production floors requiring strict air-leakage prevention and easy sanitization.

Food & Beverage Processing: Washdown-frequent areas utilizing AISI 304/316 Stainless Steel corrosion-resistant frames.

Available Types & Configurations

Model HZ-S100 (Standard Indoor)

Optimized for high-frequency internal logistics corridors and warehouse segregation.

FAQ

Q: What happens if a forklift hits the door curtain at high speed?

A: The zipper edge disengages cleanly from the polyethylene side track without tearing or fracturing the fabric. On the next open or close command, the automatic re-insertion mechanism guides the zipper back into alignment, restoring full operation without technician intervention.

Q: How does the Cold Storage model prevent track freezing at -30°C?

A: Model HZ-C500 features low-voltage, thermostatically controlled heating cables integrated directly within both side tracks and the motor enclosure, preventing condensation freeze-up and ensuring uninterrupted movement.

Q: What power supply and electrical connections are required?

A: Standard units operate on 3-Phase 380V / 50Hz (single-phase 220V options available for smaller clear openings up to 3m x 3m). Power consumption ratings range from 0.75kW to 2.2kW.

Q: Can the door integrate with our existing warehouse automation systems?

A: Yes. The onboard PLC control system provides standard potential-free inputs and outputs, allowing seamless integration with conveyor belts, automated guided vehicles (AGVs), airlock systems, and fire alarm triggers.

Q: What compliance standards do these doors meet?

A: Our high-speed zipper doors are manufactured in compliance with CE safety directives, ISO 9001 quality management standards, and EN 12424 wind resistance specifications. Complete technical dossiers and test reports are available for engineering review.
