Open-type water spray protection systems are typically designed per NFPA 15 or similar design standards and are acceptable for protecting against hazards involving; flammable or combustible materials, electrical hazards, propellants, pyrotechnics, and similar life/safety situations. BETE spray nozzles are used for cooling, evaporation, and wetting in water deluge systems.
Open-type deluge nozzles and systems typically maintain dry supply piping. With the use of heat, smoke, or flame detection equipment, a deluge valve opens and supplies water and pressure to the nozzle for operation. These differ from automatic systems in which automatic nozzles use a heat-sensitive element to maintain a closed orifice and retain the water/pressure of the supply piping system until activated.
Common Uses And Industries
Important factors to consider:
Size & shape of the target area, equipment, or enclosure
Applicable design specifications and requirements
- Required flow rates/coverage densities
Available nozzle mounting locations
Available pressure drop (∆P) across the nozzle
- ∆P = supply pressure at nozzle inlet – process pressure outside nozzle
As a nozzle manufacturer, BETE Fog Nozzle, Inc. cannot assume responsibility for the design of life/safety systems
