74 Degree Fast Response Type Fire Sprinkler

The Early Suppression Fast Response (ESFR) sprinkler is a sprinkler that uses fusible alloy welding parts as the temperature sensing element. The sprinkler has a flow coefficient of K=17 and a specially designed splash plate, so that the sprinkler sprays large-diameter, high-energy water droplets And form a hemispherical water flow below it. This characteristic allows the water droplets to penetrate the flame while cooling the hot air formed in the early stage of the fire, directly cooling the combustion body, so the sprinkler has a special advantage for protecting high stack warehouses.
