A water wall is a spray of water that acts as a barrier to shield personnel and equipment against radiant heat, harmful gases, and flames. The more water sprayed to form the suppression wall, the better the fire protection and shielding. High pressure and flow rates project water faster and further to form a larger buffer between the heat source and the protected areas.
Flat fan nozzles can produce an adequate barrier for some applications. However, full cone nozzles, particularly wide coverage spiral nozzles, are usually superior as they form a cone of liquid rather than a very thin plane of liquid. The spray pattern of BETE’s spiral full cone nozzles produces multiple concentric cones, which form two to three bands of relatively coarse droplets surrounding broad bands of finer droplets. The tiny droplets are ideal for cooling, while the large droplets are ideal for wind resistance and heat removal.
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
