A Water Spray System, for Fire Protection a different variant of Fire Sprinkler System. Such a system is used in places where fire is likely to rapidly spread out of control, within a short duration. Examples of such places, where Water Spray System, for Fire Protection are required are; Transformers, LPG bullets and Combustible fuels.

It depends on the type of system, equipment or inflammable liquid, in use. If however, you are using any substance that are highly inflammable, combustible or catch fire and spread quickly. This system is a mandate for you.

Let us take an example to be more specific and clear. In an oil cooled transformer, the oil is likely to catch fire after a certain temperate is exceeded and instantly the entire transformer will catch fire and burn from all sides; even though the transformer is made up of metal. To avoid this, kind fire, we use Water Spray System.

Here, there may be multiple metal rings of detectors; a detector is nothing but a temperature sensing element. This detector ring is placed next to the most likely sots where the temperature is about to exceed or fire is about to take place. Also the, entire transformer is surrounded by multiple sprays, at multiple levels. A spray is nothing, but a sprinkler without the temperature sensing, bulb.

When the fire does take place, the detector ring detects this; and gives the signal to the deluge valve or the entire sprinkler surrounding the transformer to start all at once. Hence the entire transformer is flushed with water, to cool it down.

There are two variants of Water Spray System, for Fire Protection:

  • High Velocity Water Spray Systems (HVWS)
  • Medium Velocity Water Spray Systems (MVWS)

HIGH Velocity Water Spray Systems (H.V.W. S. Systems)

High Velocity Water Spray Nozzles, This system works uniquely effective against fire hazards involving heavy or medium oil. This systems operates using the specifically designed nozzles depending on the fire area, requirement of shape of spray cone and the water flow. This system has capacity to reach to the surface of burning oil penetrating the flame zone .This results into most important phenomenon called ‘Emulsification’ i.e. formation of the non-combustible emulsion layer of oil-water on the surface of the burning oil. This emulsification along with the cooing smothering effects extinguishes the fire.
High Velocity Water Spray Systems also can be used to protect Circuit Breakers & Transformers.

Medium Velocity Water Spray Systems (M.V.W.S. Systems)

Medium velocity water spray sprayers provide a continuous water spray with medium velocity consisting of finely divided water droplets. These systems are ideal in fighting against the fire involving light oils. As emulsification is not possible in this case, the high velocity water spray systems cannot work in this type of fire.

These systems sprayers are mostly used in combination with the other effective fire fighting systems. The specifically designed nozzles produce a cooling spray which has very high capacity to absorb the heat This water jet is sprayed on the adjacent plants and structures which ultimately minimizes the damage and the risk of explosion.
