The ultra-fine dry powder automatic fire extinguishing device can instantly start extinguishing fire when encountering fire or fire signal, which embodies the advanced fire protection concept of "quick response, early suppression, and efficient fire extinguishing". It is a cutting-edge technology that countries around the world are competing to develop. It is suitable for archives, front and rear warehouses, kitchens, offices, construction sites, warehouses, oil depots, safes, archives, telecommunications base stations, gas stations, substations and other places.

Ultrafine dry powder fire extinguishing technology is the most efficient fire extinguishing technology today. Since the fire extinguishing time is usually less than 5 seconds and there is no requirement for the sealing of the application site, it is very suitable for protecting objects in fully enclosed spaces, semi-enclosed spaces or outdoor open spaces.

The ultra-fine dry powder fire extinguishing device (fire extinguishing system) is composed of an ultra-fine dry powder fire extinguishing device (fire extinguishing system), a starting component, a fire power supply and a display panel.

According to the type of ultra-fine dry powder fire extinguishing device, it is divided into: vehicle ultra-fine dry powder fire extinguishing device (small car, large passenger car or truck, train fire extinguishing device), suspended ultra-fine dry powder automatic fire extinguishing device (non-pressure storage suspension type, pressure storage suspension type, solid-gas conversion type), cabinet ultra-fine dry powder fire extinguishing device/system (non-pipeline type, pipe network type), ultra-fine dry powder fire extinguishing bomb, and general mobile ultra-fine dry powder fire extinguishing device.

Fire extinguishing principle

Temperature control: When the ambient temperature rises to the set nominal value, the valve on the fire extinguishing device automatically opens to release the ultra-fine dry powder fire extinguishing agent to extinguish the fire.

Thermal initiation: In a specific environment, when the fire extinguishing device needs to be quickly activated, the fire signal is quickly transmitted to the fire extinguishing device through the thermal sensitive line to activate the release of ultra-fine dry powder fire extinguishing agent to extinguish the fire. Thermal initiation can be started by a single device or multiple devices can be linked.

Electronic control: The electronically controlled fire extinguishing device can be connected to all fire alarm controllers and can output feedback signals during spraying. The detection device detects the composite fire signal and sends it to the fire alarm controller. The controller confirms and outputs the command signal (the command signal is divided into passive switch signal and active energy signal). The command signal starts the fire power supply to the fire extinguishing device through the repeater to open the valve and release the ultra-fine dry powder fire extinguishing agent to extinguish the fire.
