Special-type Steel Fire Shutter with Water Mist (Vertical Rolling Type)

1. System Overview

The Special-Type Steel Fire Shutter with Water Mist System (Vertical Rolling Type) is a high-performance fire separation assembly that integrates a steel fire shutter with an automatic water mist cooling system.
During a fire event, the shutter descends vertically to form a physical fire barrier, while a continuous water mist layer is simultaneously discharged onto the shutter surface to provide cooling and protection, significantly enhancing the overall fire resistance and thermal insulation performance.

This type of special-type steel fire shutter with water mist protection is widely used in buildings with large openings, very high fire-resistance requirements, and long-term operational reliability demands. It is a proven, high-level fire compartmentation solution commonly adopted in large public buildings and critical protected areas.

2. Key Advantages

1. Steel construction combined with water mist cooling for superior fire resistance

The shutter is constructed of high-strength steel, and the water mist system provides continuous surface cooling during a fire, effectively reducing thermal exposure and meeting special-type fire-resistance requirements.

2. Vertical rolling configuration with reliable compartmentation

The vertically descending shutter design is mature and reliable. Once fully deployed, it forms a continuous and stable fire barrier, suitable for standard and large opening applications.

3. Effective reduction of unexposed surface temperature rise

A uniform water mist cooling layer forms on the shutter surface, significantly reducing radiant heat transfer and improving safety in adjacent compartments.

4. Low water consumption with minimal water damage

The water mist cooling method requires substantially less water than conventional sprinkler systems, reducing water usage and minimizing secondary water damage.

5. Single-curtain design with reduced space requirements

A single curtain structure is used. Compared with special-type inorganic fire shutters employing double curtains, this design occupies less space.

6. Reliable smoke control performance

The steel curtain combined with sealed guide rails effectively limits smoke leakage while blocking flames, meeting smoke compartmentation design requirements.

7. System interlocking for safe and controlled operation

The system can be interlocked with the fire alarm system and sprinkler or water mist systems, ensuring automatic shutter descent and synchronized water mist activation during a fire.

3. Operating Principle

1. Under normal conditions, the steel fire shutter is rolled up above the opening, and the water mist system remains on standby.

2. Upon fire detection, the fire alarm system issues an activation signal.

3. The fire shutter control unit is activated, and the shutter descends vertically along the guide rails to close the opening.

4. A temperature-activated release valve operates upon heat exposure, allowing water to flow through the spray piping and form a continuous water mist layer on the shutter surface for cooling and protection.

5. Throughout the fire event, the shutter and water mist system      operate together to form a high-grade fire and smoke barrier.
