Detail of MW Nozzle Water Mist

Water mist protection systems are typically designed per NFPA 750 or similar design standards, which provide minimum requirements for mist systems that extinguish, contain, or cool applicable fire or hazards by absorbing heat, displacing oxygen, and blocking radiant heat.

BETE water mist nozzles can effectively fill a contained area with the fine water droplets required by water mist systems for effective operation. The heat of fire easily vaporizes the low volume flow and high evaporation rate of water mist sprays. These absorb heat and displace oxygen, which suppresses the fire while minimizing damage to water-sensitive equipment or other assets that would otherwise be destroyed by water damage in high flow deluge systems. Professionals are increasingly turning to water mist systems instead of previous system designs, such as Halon systems, due to environmental concerns and increasing regulations, and the proven capabilities of water mist systems.
