External Water Spray SYstems

•  Fire required Oxygen, Heat and Fuel to sustain itself, remove one of these and the fire is extinguished. 
• A bushfire travels quickly because the wind pushes the heat and fire brands ahead of it, preheating any material for faster ignition. Applying water an area will significantly slow the advance of a fire front.
• Airbourne water droplets will help extinguish fire brands, stopping spot fires igniting and significantly slowing the advance of a bushfire.
• Wetting the foliage and ground cover will increase the vegetations fire resistance, making it harder to ignite.
• Wetting a structures surfaces helps to extinguish hot embers before they can heat up and ignite. 

•  Water is supplied to the sprinklers by a pump fed by from a Static Water Source. The pump can be fuel or electric driven and may be remote start or manual start.
• The sprays are strategically positioned around the perimeter of the structures and the landscape to target flying embers before they can reach combustible materials.
• A well designed system can deliver a water efficient system that utilises your resources to provide a barrier of water between the fire front and your property. 
• Large water droplets are effected less by high winds that accompany a Bushfire. The Rainmaker Drencher Heads are specifically designed for this. 

Your level of protection should be related to your Bushfire Attack Level Number, we have listed our minimum equipment recommendations in the About Spray Systems Folder.

We recommend having a multi layered spray system, 

• Outer Zone which uses Soakers (Impacts) to wet a large area and increase the humidity of your property in a high fire danger period. 
• Inner Zone which uses Drencher Heads or Nozzles to throw up a shield of water around your home as the fire front approaches.
• Flame Zone which uses window and wall drenchers to throw water directly onto your homes surfaces when the front arrives.

All our spray heads have been designed with this strategy in mind.
