Sprinkler System
A sprinkler is a device commonly used in firefighting. It is made up of an “armor”, a sensitive element called a bulb. The sprinkler nozzle is threaded to a pressurized piping and remains closed by a cap locked by the bulb. Inside the bulb a liquid expands at a certain temperature so that the capsule will rupture when a fire starts, releasing the water to fight.
