Product drawing

Aerosol fire suppression system Working principle

Condensed aerosol fire extinguishing gas generating agent is a solid chemical mixture composed of oxidant, reducing agent, combustion speed control agent and binder. After starting by heat (electricity), the reaction product is cooled and forms agglomerated sol state. Under the action of heat, the fire extinguishing gas Affinity reaction occurs between the sex groups, which repeatedly consumes a large amount of active groups, reduces the burning free radicals, and efficiently absorbs and neutralizes the burning free radicals in the flame, so as to achieve chemical suppression and extinguishing effect.

Aerosol fire suppression system Calculation

The calculation formula are as below:

W=C2 * KV * V

Here by W is aerosol quality in kg, C2 is design application density in kg/m³.

And in design it is normally use design density of 100 gram cover per 1 cubic meter, for example, a 100 gram of china strontium nitrate aerosol compound cover 1 cubic meter space, 250 gram cover 2.5 cubic meter, and so on.

Aerosol fire suppression system design in electric vehicles

The aerosol fire suppression system is a new-style fire extinguisher. It is specialized made for Small enclosed space that require automatic fire extinguishing and are not suitable for fire extinguishing with water or dry powder extinguishing agent. It can detect and suppress the early fire to avoid every fire hazard. Now it is widely used in energy storage system, Electrical cabinets, Electrical panel, Battery compartment, Passenger cars, Vehicles and SUV engine compartments, to automatically suppress the fire by self heat-detecting and self activation.
