Hanging Heptafluoropropane Fire Extinguishing System
The suspended heptafluoropropane gas fire suppression system (temperature-sensitive type) consists of a fire extinguishing agent cylinder, a temperature-sensitive release assembly, a suspension bracket, a pressure gauge, and other components. It does not require installation of fire extinguishing agent delivery pipelines, does not need a dedicated cylinder room, and does not need to be linked with a fire alarm system. It can be installed either by suspension or wall mounting. When a fire occurs, the temperature-sensitive glass bulb breaks, triggering the temperature-sensitive release assembly to open and directly spray the fire extinguishing agent into the protected area. As a result, there is no pipeline loss of the extinguishing agent, leading to faster extinguishing speeds and higher efficiency.

Overview
The suspended heptafluoropropane gas fire suppression system (temperature-sensitive type) consists of a fire extinguishing agent cylinder, a temperature-sensitive release assembly, a suspension bracket, a pressure gauge, and other components. It does not require installation of fire extinguishing agent delivery pipelines, does not need a dedicated cylinder room, and does not need to be linked with a fire alarm system. It can be installed either by suspension or wall mounting. When a fire occurs, the temperature-sensitive glass bulb breaks, triggering the temperature-sensitive release assembly to open and directly spray the fire extinguishing agent into the protected area. As a result, there is no pipeline loss of the extinguishing agent, leading to faster extinguishing speeds and higher efficiency.
Fire extinguishing principle
When a fire occurs within the protected area, the temperature-sensitive glass bulb on the suspended heptafluoropropane gas fire suppression system (temperature-sensing type) expands upon heating, causing it to rupture and open the valve, thereby releasing the extinguishing agent to put out the fire.
