K=17 (242) ESFR 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.
Model ESFR 242/68°C P Pendent Sprinklers are mainly composed of frame, sealing element, ball seat, spring, action mechanism, fusible alloy sheet, screw, splash plate, etc.; the sprinkler adopts welded fusible element as the action element, which is connected by two identical The parts are connected through the welding layer of the fusible element. When the operating temperature is reached, the welding layer is melted, the connecting parts are separated, and the sprinkler head starts to sprinkle water.
