High Pressure Water Mist Nozzle For Fire Fighting
SKU: XSWT Series | Category: Fire Protection Equipment
High pressure water mist nozzles are critical components in modern fire suppression systems, delivering superior cooling and oxygen displacement through ultra-fine mist technology. Engineered with premium stainless steel construction and advanced vortex spray design, these nozzles produce droplets smaller than 100μm for optimal fire suppression performance and water efficiency.
Product Overview
The high pressure water mist nozzle operates by forcing liquid through precision orifices at controlled pressure, creating intense friction with ambient air that transforms the flow into a fine, uniform mist. This Grade I mist spray (Dv0.9 ≤ 100μm) provides extended dwell time, superior spreading characteristics, and significant water savings compared to conventional fire suppression methods.
Key Features
- Ultra-Fine Mist Technology: Average droplet size below 100μm with dense, uniform distribution and extended airborne dwell time
- Stainless Steel Construction: Manufactured from SS316 and SS303 for superior corrosion resistance and durability
- Advanced Vortex Spray Design: Optimized inner flow passage geometry overcomes air resistance for extended spray range and improved droplet distribution
- Non-Blocking Filter: Integrated SS304 filter prevents clogging and ensures consistent performance
- Rapid Response Activation: German-engineered JOB glass ball thermal element provides quick reaction to temperature changes during fire events
- Multiple Spray Angles: 120-degree spray pattern with model variations to minimize droplet collision and optimize misting performance

How It Works
The nozzle comprises four primary components: nozzle tip, nozzle body, nozzle core, and filter assembly. Pressurized liquid passes through the precision-engineered core and exits through multiple orifices, where high-velocity flow creates intense friction with surrounding air. This aerodynamic interaction breaks the liquid stream into fine droplets that disperse uniformly across the 120-degree spray pattern.
Applications
High pressure water mist nozzles are essential for public fire protection systems, particularly in enclosed and sensitive environments. The technology effectively suppresses fires through three mechanisms: direct cooling of the fire source, steam generation that displaces oxygen, and reduction of radiant heat. This multi-mechanism approach makes water mist systems ideal for protecting valuable assets while minimizing water damage and environmental impact.
