Protecting Lives and Assets with High Pressure Water Mist Technology

Sep 18, 2023 | news

As building heights and population densities increase worldwide, advanced fire protection strategies become evermore important for life safety. High pressure water mist system exemplify innovative solutions effectively controlling severe hazards with minimal environmental impact.

Traditional Methods Challenged

While sprinklers reliably combat ordinary combustibles, their water volumes threaten sensitive equipment and documents. Gases like oxygen fiercely accelerate jet/pool gasoline fires faster than sprinklers can control. Dry pipe valves delay fire detection in roof spaces. Chemical systems pose eco/health concerns. Clearly new tactics were needed.

The Science of Water Mist

Pioneering research revealed ultra-fine mist atomized via high pressures above 180 bar interacts aggressively with flame chemistries. By absorbing over 580 times its heat of vaporization per unit volume, water rapidly suppresses combustion through both physical and chemical pathways. Mists penetrate tightly sealed enclosures extinguishing all fire phases before flashover.

Engineering Water Mist Systems

Stainless steel pipe networks adjust to any geometry. Non-pressurized distribution piping couples with wall-mounted HPLP (high pressure low pressure) mist nozzles activated by fusible bulbs, detectors or manual pull stations. Controls monitor pressure/flow regulating a centralized pump skid. Low standby pressures minimize hydrostatic forces on structures.

Proven Performance

Full-scale atrium/tunnel tests proven mist’s efficiency versus hydrocarbon pool/rack fires inminutes rather than sprinkler hours. Certified per UL/LPCB/FM Global, installations protect data centers, archives, clean rooms, ships’ engine spaces, airports and hotels from incendive hazards or passenger hazards like lithium battery fires. Analysis confirms negligible residuals versus deluges.

Sustainability Through Performance

Water consumption and cleanup times decrease tenfold over sprinklers. Chemical-free mists prevent pollution while enabling confined space access immediately post-fire. Enhanced risk assessments optimize safety and revenue continuity for critical facilities housing society’s information backbone and infrastructure.

As fire risks multiply, high pressure water mist technology empowers architects, owners and authorities to leverage life safety proactively through scientifically advanced yet passively dependable solutions. Resource stewardship joins inhibited flames maintaining high occupancy comfort.
