Early suppression and rapid response sprinkler heads
Early fire extinguishing rapid response sprinkler heads are large-flow special sprinkler heads designed specifically to deal with severe fires and protect high-stack and high-shelf warehouses.
The sprinkler head can respond quickly to a spreading high-risk fire, and under the combined effect of large water droplets and fast flow rates, it can spray large amounts of water in a timely manner to extinguish the fire, not just control the fire.
According to the standards and standards, it is confirmed that the nozzle can be used in warehouses up to 100 meters and shelves with a height of 100 meters. The splash plate and frame of this type of sprinkler head form a wide symmetrical area, thus ensuring that while the sprinkler head extinguishes the fire on the upper part of the shelf, there is a powerful water column in the center of the sprinkler head that can pass through the shelf to extinguish the fire at the bottom of the shelf below the sprinkler head.
