WATER MIST FIRE PROTECTION SYSTEMS

Advantages of High-Pressure Water Mist Systems: A Comprehensive Overview

High-pressure water mist systems have emerged as a revolutionary solution in fire protection, offering a unique blend of efficiency, safety, and environmental sustainability. This article delves into the key advantages of these systems, supported by technical insights and real-world applications.

1. High-Efficiency Fire Suppression

High-pressure water mist systems utilize a dual-mechanism approach: intensive cooling and oxygen deprivation. When water is pressurized (typically above 10 MPa) and released through specialized nozzles, it forms microdroplets (10–100 μm) that rapidly vaporize upon contact with heat. This vaporization absorbs over 1,700 times the heat of conventional water sprays, instantly reducing the fire temperature and preventing re-ignition . Studies show that these systems are 200–300 times more effective than traditional sprinklers, using only 1% of the water volume while achieving comparable or superior results .

2. Environmental and Economic Sustainability

Compared to gas or foam systems, high-pressure water mist uses water as its sole extinguishing medium, eliminating harmful chemicals and reducing environmental impact. The water employed is often demineralized, ensuring it does not corrode electrical equipment or leave residues . Additionally, the system requires minimal water storage infrastructure, as it can utilize local water sources, thereby saving valuable space in facilities like data centers and high-rise buildings . The cost of maintenance is also lower, as the system operates with fewer moving parts and can be easily tested without discharging water .
