Hot Aerosol Automatic Rail-Mounted Fire Suppression Unit

Wzonpa, a leading China manufacturer, supplier, and factory of advanced fire safety systems, presents the Hot Aerosol Automatic Rail-Mounted Fire Suppression Unit, a compact and highly efficient solution designed for enclosed electrical environments. The Hot Aerosol Automatic Rail-Mounted Fire Suppression Unit is engineered for rapid fire detection response and automatic activation, delivering immediate suppression through aerosol-based chemistry. It is widely used in distribution cabinets and compact electrical enclosures where traditional systems are impractical.

The Hot Aerosol Automatic Rail-Mounted Fire Suppression Unit operates without high-pressure cylinders or complex piping, making it easy to install and highly reliable in extreme environments ranging from -50°C to +90°C.

Working Principle

1.Solid-State Aerosol Reaction Technology

The Hot Aerosol Automatic Rail-Mounted Fire Suppression Unit uses a solid chemical mixture composed of:

Oxidizing agents

Reducing agents

Combustion control additives

Binder materials

Once electrically or thermally triggered, the system undergoes a controlled oxidation-reduction reaction, generating dense fire-extinguishing aerosol particles.

2.Multi-Mechanism Fire Suppression

The Hot Aerosol Automatic Rail-Mounted Fire Suppression Unit extinguishes fire through:

Thermal absorption: metal salt particles absorb heat and rapidly reduce flame temperature

Chemical inhibition: free radicals in flames are neutralized by active ions

Oxygen reduction: N₂ and CO₂ dilute oxygen concentration

Total flooding effect: aerosol remains suspended to reach hidden fire points

The Hot Aerosol Automatic Rail-Mounted Fire Suppression Unit ensures full enclosure protection even in complex cabinet layouts.

Step-by-Step Working Process

Step 1: Mounted on standard rail inside distribution cabinet or fixed with adhesive

Step 2: Fire detection triggers automatic activation

Step 3: Aerosol is released within seconds, filling the space

Step 4: Fire is extinguished rapidly by combined physical and chemical action

The Hot Aerosol Automatic Rail-Mounted Fire Suppression Unit ensures near-instant response in critical electrical faults such as short circuits.

Technical Advantages

Dosage: 10g compact charge

Protection space: ≤0.1㎡ targeted enclosure

Spray time: ≤6 seconds

Service life: 6 years stable agent validity

Maintenance: maintenance-free during validity period

Extreme temperature tolerance: -50°C to +90°C

Unlike traditional systems, the Hot Aerosol Automatic Rail-Mounted Fire Suppression Unit eliminates the need for pressurized tanks and reduces installation complexity.

Product Applications

The Hot Aerosol Automatic Rail-Mounted Fire Suppression Unit is widely used in:

Electrical distribution cabinets

Control panels and switchgear

Battery compartments

Industrial automation systems

Communication equipment enclosures

The metal salt particles in the aerosols absorb a large amount of heat at high temperatures, thereby reducing the flame temperature and suppressing combustion reactions. At the same time, under the action of heat, the vaporized metal ions and cations in the extinguishing aerosol gas can undergo affinity reactions with the active groups in combustion, repeatedly consuming a large amount of active groups, reducing combustion free radicals, and efficiently absorbing combustion free radicals in the flame, achieving chemical inhibition. The N2 and CO2 in aerosols can reduce the oxygen concentration during the combustion process and achieve fire suppression through the synergistic effect of multiple fire extinguishing mechanisms, including physical and chemical processes. The aerosol formed by solid particles wrapped in the extinguishing gas can be suspended and dispersed to various corners for a long time, achieving efficient fire extinguishing through total flooding.

Step1. Install the Hot Aerosol Fire Extinguishing Device and other components together on the standard guide rail of the distribution cabinet.（It can also be glued to other positions of the distribution cabinet）

Step2: When a short circuit or other reasons cause a fire inside the distribution cabinet, the Hot Aerosol Fire Extinguishing Device will be automatically triggered.

Step3. After the Hot Aerosol Fire Extinguishing Device is automatically triggered, it will release a large amount of aerosol, which reduces the oxygen content in the distribution cabinet and rapidly cools down in just a few seconds. The metal salt particles in the released aerosol will quickly absorb a large amount of heat, thereby reducing the flame temperature and suppressing the combustion reaction.

Step4: Within seconds, the fire was extinguished by the aerosol released by the Hot Aerosol Fire Extinguishing Device
