1.5MPa pressurized ultra-fine dry powder fire extinguishing device
Operating Principle: Upon detection of a fire in the protected area by the fire detector, the fire alarm controller confirms the fire and issues a command to activate the cabinet-type fire extinguishing device. The central nitrogen cylinder of the extinguishing device fills the lead storage tank with pressurized nitrogen. When the pressure in the lead storage tank reaches the working pressure, the extinguishing agent tank valve automatically opens to release the extinguishing agent for fire suppression.
