MA 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 all the sprinkler surrounding the transformer to start all at once. Hence the entire transformer is flushed with water, to cool it down.

HVWS, is generally used in oil based systems, having high flash points. The velocity of the water sprays, hitting the system under fire is critical for successful fire extinguishing action.

MVWS, is generally used in oil based systems, having low flash points. The velocity of the water sprays, hitting the system under fire, if it is high, might actually spread the fire, and not extinguish it. Hence, the velocity of the water has to be in range.
