Special Type Inorganic Fire Curtain (Folding Lift Type)

1. System Overview

Special Type Inorganic Fire Curtain (Folding Lift Type) is a high-performance fire compartmentation system that utilizes an inorganic, noncombustible fire-resistant curtain combined with a folding and lifting operating mechanism.
Under normal conditions, the curtain is stored in a folded configuration above the opening or within adjacent side spaces. Upon activation during a fire event, the curtain rapidly deploys and descends, forming a high fire-resistance and high thermal-insulation fire and smoke barrier between fire compartments.

Compared with conventional vertically rolling fire curtains, the folding lift type special inorganic fire curtain offers significant advantages in buildings with restricted headroom, complex structural conditions, or high architectural and space-utilization requirements. It is widely used as a preferred fire separation solution in premium public buildings and critical protection areas.

2. Key Advantages

1. Inorganic, Noncombustible Materials with Special-Grade Fire Resistance

The curtain is manufactured from inorganic fire-resistant materials that are noncombustible and non-melting, maintaining structural integrity under severe fire exposure and meeting special-grade fire-resistance requirements.

2. Folding Lift Structure, Adaptable to Irregular Geometries

The folding storage and lifting operation allow customization to suit architectural features, enabling irregular configurations such as L-shaped, U-shaped, enclosed (box-shaped), and curved layouts.

3. High Thermal Insulation Performance

The composite thermal-insulation design effectively reduces unexposed-face temperature rise, minimizing radiant heat transfer and improving safety in adjacent compartments and egress routes.

4. Reliable Smoke Control Performance

With a dense curtain structure combined with guide rail and sealing systems, smoke leakage is effectively controlled, complying with smoke compartmentation design requirements.

5. Automatic Interlock and Stable Operation

The system can be interlocked with the fire alarm system to automatically deploy and descend during a fire event, while also supporting manual operation, ensuring safe and reliable performance under emergency conditions.

3. Operating Principle

1. Under normal conditions, the fire curtain is stored in a folded configuration within the designated installation space, without affecting building functionality or aesthetics.

2. When a fire occurs, the fire alarm system sends an activation signal to the control unit.

3. The drive system is activated, and the folded curtain progressively deploys and lifts/descends vertically.

4. Once fully deployed, the curtain forms a continuous and complete fire- and smoke-resistant barrier between fire compartments.

5. After the fire event and upon manual confirmation of safety, the system may be reset to its standby condition.
