ZSTYR Series Fusible Alloy Sprinkler（pendant type）
Product Introduction:
Acting as a main component in the automatic water spraying and fire extinguishing system, ZSTYR series fusible alloy sprinkler(K=363) is the one with the fastest flow and largest aperture in the world nowadays. Not only it could be used to defect fire hazard, but also it could put out fire through spraying water automatically.The temperature-sensing device could be switched on automatically and rapidly at the fire initial stage, and meanwhile the water with certain impetus couldbe distributed according to stipulated shape and density in the designed protection area, which makes it become the only fire extinguishing sprinkler for inhibiting early-stage fire. With the large nozzle diameter, relatively large deflector and response time index of (FTI)≤28±8（m.s）0.5, it is equips with the advantages such as quick response to fire, water-spraying with high flow and so forth. It is designed dedicatedly for dealing with warehouse fire with high degree of risk. Being made of fusible alloy, the temperature-sensing device could sense large area,which quickens the response time greatly. This device is widely applied toprotect high stacking, high-goods shelf store house, store house with mixed articles, and to store plastic products as well. It is particularly suitable for store house without heat preservation measures in cold areas.
Specifications:
The response time index forthe device is (RTI) ≤28±8(m.s)0.5
