Product introduction

This product is a sprinkler with fusible alloy as the temperature sensing element. Except for the root thread, all or part of the body of the sprinkler is installed in the sprinkler embedded in the shield of the ceiling. The sprinkler assembly contains a small fusible solder element. When exposed to enough heat from the fire, the solder melts and the internal parts of the sprinkler fall off. At this time, the sprinkler starts and the deflector drops to its operating position to allow water to flow. It has the characteristics of stability, firmness, durability, environmental protection, antifreeze and so on, which can not be compared with the sprinkler with ordinary glass bulb as the temperature sensing element. The appearance design is novel, beautiful and compact, easy to install, and there is no need for the secondary action after the decorative ring falls off, so it’s fire extinguishing function is more timely.
