Water Mist Fire Suppression System

Water mist is so effective (and uses very little water) due to the process of breaking the water into millions of tiny droplets.  This provides the water with a significantly larger surface area, enabling it to absorb the heat of the fire.  As the water absorbs the radiant heat (which is what causes fire spread and flashover), the tiny droplets quickly turn to steam which expands, displacing the oxygen and creating an environment where there is insufficient oxygen for flames to occur.  This means that, of the three elements in the Fire Triangle, two (Oxygen and Heat) are removed.
