Water Mist Fire Suppression
Water Mist Fire Suppression delivers fast and efficient fire control using high-pressure nozzles that create ultra-fine droplets, quickly absorbing heat and reducing oxygen.
Overview
- Heritage sites, hotels, public areas and transport hubs
- Data rooms, control rooms and archives
- Industrial machinery spaces and turbines
- Significantly lower water usage vs. sprinklers
- Rapid cooling and steam inerting at the flame
- Less collateral damage and quicker recovery
- Sprinklers: proven for broad occupancies.
- Clean Agent: residue-free for electronics.
- Aerosol: compact for cabinets/enclosures.
How It Works
High-pressure nozzles atomize water into micro-droplets. The vast surface area extracts heat rapidly while forming localized steam that reduces oxygen where combustion occurs.
- Fast heat absorption and flame knock-down
- Limited visibility impact vs. traditional spray
- Lower runoff and cleaner post-event conditions
Systems can be open-nozzle (deluge with detection) or automatic nozzle types. Detection and control logic coordinate pumps, valves and equipment shutdowns.
- Interfaces with fire alarm and BMS
- Pump start, zone selection, and post-ventilation
- Manual release and local indicators
Design & Validation
Performance depends on nozzle type, pressure, spacing and obstruction effects. We base layouts on validated data and match pump capacity to simultaneous demand.
- Hazard class, ceiling height and compartment size
- Nozzle spacing, orientation and shadowing
- Water quality, filtration and materials
- Pressure/flow balance across branches
- Pump curves, accumulator and relief design
- Test connections and acceptance criteria
- Layouts, valve schedules and isometrics
- Cause-and-effect matrix and interlocks
- Commissioning plans and maintenance guides
