High-Pressure Water Mist Fire Suppression, Engineered in India

Mistelix designs and manufactures 100–140 bar water mist systems for the risks that punish under-engineered fire protection: tunnels, paint booths, cable galleries and transformers.

How it works

Three mechanisms, one discharge

  • Cooling

    Fine droplets flash to vapour, absorbing heat far faster per litre than a coarse sprinkler spray.

  • Local oxygen displacement

    Vapour expansion displaces oxygen at the seat of the fire, starving combustion without flooding the space.

  • Radiant heat attenuation

    The droplet cloud blocks radiant heat transfer, slowing fire spread to adjacent fuel and protecting escape routes.

Applications

Built for the risks that punish shortcuts

Road & rail tunnels

Zoned deluge water mist protection for tunnel bores, sized to 25–30 m fire zones with section-valve activation.

25–30 m zones

Paint booths

NFPA 33 / NFPA 750 conformant suppression for spray booths — fast knockdown, minimal water damage, quick restart.

NFPA 33 + 750

Cable tunnels

Protection for metro and power utility cable galleries where uptime and asset survival matter as much as suppression.

Utility infrastructure

Transformers

Oil-filled transformer bay protection with a fraction of the water footprint of a deluge system.

Compact footprint

Engineering

Manufactured to be tested, not just installed

Every pump skid is hydrostatically tested before it ships. Every mapper of nozzle to zone is documented. See how Mistelix builds and verifies its systems.
