Automatic fire extinguishing device for public transport engine compartment

Automotive Ultra-Fine Dry Powder Automatic Fire Extinguishing Device for Bus, Coach and Car Engine Compartment FZXA0.3

◆Product Type: Automotive Ultra-Fine Dry Powder Automatic Fire Extinguishing Device;

◆Charging Fire Extinguishing Agent Type: ABC Ultra-Fine Dry Powder Fire Extinguishing Agent, Alkyl Aluminum Fire Extinguishing Agent;

◆Extinguishing Principle: Due to the small particle size and good flowability of the charged fire extinguishing agent, it has good resistance to re-ignition, dispersion, and electrical insulation. Its extinguishing mechanism is mainly based on chemical extinguishing. It extinguishes flames through dual chemical and physical functions: It physically isolates the protected object from air and blocks the oxygen required for re-combustion to prevent re-ignition in a physical way; Chemical-wise, the released ultra-fine dry powder fire extinguishing agent powder of the automatic fire extinguishing device comes in contact with the combustion material flame to rapidly take away free radicals and heat through chemical reactions, thus cutting off the combustion chain and achieving flame extinguishing. The large amount of vitreous substances generated by the reaction between the fire extinguishing agent and the flame is adsorbed on the surface of the protected object to form an isolation layer. Therefore, it can be used for both fully submerged extinguishing in a relatively enclosed space and local protection extinguishing in an open place.

◆Charging fire extinguishing agent weight kg: 0.3

◆Numbering specification: FZXA-series;

◆Applicable places: Applicable to the engine compartment of automobiles.

◆Detailed Description of Miniature Automotive Ultra-Fine Dry Powder Automatic Fire Extinguishing Device FZXA Series: The FZXA series miniature automotive ultra-fine dry powder automatic fire extinguishing device has the following advantages:

1. The volume of the cylinder body is determined according to the gas-powder ratio to ensure efficient fire extinguishing;

2. Easy to install, fix the fire extinguishing device above the protected object;

3. Beautiful appearance, safe and reliable use;

4. The fire extinguishing agent sprayed by the fire extinguishing device has a small particle size and good flowability, can suspend in the air for a certain period of time, and can be used for both fully submerged extinguishing in a relatively enclosed space and local protection extinguishing in an open place;

5. Multiple starting modes to choose from:

a. Temperature Control: When the ambient temperature rises to the set nominal value, the valve on the fire extinguishing device is automatically opened, and the ultra-fine dry powder fire extinguishing agent is released for fire extinguishing.

b. Thermal Initiation: In specific environments where the fire extinguishing device needs to be quickly started, the fire alarm signal is quickly transmitted to the fire extinguishing device through the thermal sensitive wire to start and release the ultra-fine dry powder fire extinguishing agent for fire extinguishing. The thermal initiation can be started singly or in multiple linkages.

c. Electrical Control: The fire extinguishing device can be connected to all fire alarm controllers, output feedback signals during spraying, detect composite fire situation signals through detection devices and send them to the fire alarm controller. The controller confirms and outputs instruction signals (instruction signals are divided into passive switch signals and active energy signals). The instruction signals start the fire source through relays to open the valve of the fire extinguishing device and release the ultra-fine dry powder fire extinguishing agent for fire extinguishing.
