Product Introduction

Under normal circumstances, the glass bulb inside the nozzle will press against the seal, keeping the water sealed in the pipe network.

When a fire causes the ambient temperature to rise to the rated operating temperature (such as 68℃), the pressure generated by the thermal expansion of the liquid inside the heat-sensitive glass tube will exceed the tube's endurance limit, leading to the tube's rupture and thus activating the system.

After the system starts up, the pressurized water in the pipe network is forced to spray out from the nozzles and collide with the splash pan at high speed. The water flow is dispersed into fine and uniform water droplets, forming a complete water curtain that covers the designated protected area, thereby achieving efficient fire control and suppression.
