Fire protection - Water wall

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.

 

How does water wall fire protection work?

A water wall acts as a shield between the fire source and the area to be protected. 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 are commonly used and 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.

BETE's spiral nozzles create a water spray consisting of multiple concentric cones. These provide layered security zones with a mix of coarser droplets, ideal for wind drift resistance and surface wetting encapsulating and projecting smaller droplets, ideal for cooling and absorbing heat.

 

Factors to consider for effective fire protection

There are a number of important factors to consider in order to achieve an optimised fire protection solution. Our experienced staff and engineers are available to help with calculations and find the right solution.

  • Size and shape of the target area, equipment, or enclosure
  • Design specifications and requirements - required flow rates/coverage densities
  • Available nozzle mounting locations
  • Available liquid pressure drop (∆P) across the nozzle = supply pressure at nozzle inlet - process pressure outside nozzle

 

Project review and proposed solution

To deliver the optimal solution, it is important to go through in detail various factors that affect product choice, type of solution, investment objective, and other requirements at an early stage of the project.

A start-up meeting is important to find out about various factors that will affect choice of equipment and solution in order to achieve the most efficient and sustainable solution. We are happy to set up the start-up meeting as a web meeting or a site visit, depending on your preference. All details and information from the start-up meeting we will summarise and go through with you to make sure we agree on project scope and objective.

Next step, we present a proposed solution, focusing on function, lifespan, quality, choice of material, operating and maintenance costs, and environmental impact. Our goal is to deliver a sustainable solution that creates added value to your company,
