Quick temperature sensitive start: When the liquid inside the glass bubble expands due to heat and reaches 68 ℃, it quickly bursts and starts spraying water
Standard interface design: 1/2 "NPT (DN15) standard thread, easy to connect with fire pipeline systems
Reliable working pressure: supports a working pressure of 1.2Mpa, ensuring stable operation of the system under high pressure
Downward spray optimization: specially designed for downward installation, achieving uniform downward spraying and wide coverage
Automatic fire extinguishing mechanism: It automatically senses and starts in case of a fire, and sprays water in a timely manner to suppress the spread of the fire
