30g Heat Aerosol Fire Extinguishing Device

Electrical faults are among the leading causes of fires in distribution boards, control panels, battery cabinets, and server enclosures. The 30g Heat Aerosol Fire Extinguishing Device provides an automatic, self-contained fire suppression solution designed specifically for enclosed electrical spaces.

When the surrounding temperature reaches approximately 170°C or comes into direct contact with flames, the device automatically activates and releases a condensed aerosol extinguishing agent that suppresses the fire within seconds. No external power supply, control panel, piping system, or manual operation is required.

Key Features

Automatic Fire Detection & Suppression

The built-in thermal activation system continuously monitors temperature. Once a fire begins inside the enclosure, the device automatically releases aerosol extinguishing particles to stop combustion at its earliest stage.

No External Power Required

Unlike traditional fire suppression systems, this unit operates independently and requires no electrical wiring, batteries, sensors, or control modules.

Safe for Electrical Equipment

The aerosol agent leaves minimal residue and does not damage electrical components, making it suitable for sensitive equipment including PLCs, circuit breakers, communication devices, batteries, and servers.

Compact Design

Its compact size allows installation inside:

Maintenance-Free Operation

The device offers a service life of up to 10 years and requires virtually no maintenance during operation.

Environmentally Friendly

The condensed aerosol technology contains no ozone-depleting substances and provides a clean, sustainable fire suppression solution.

How It Works

The Heat Aerosol Fire Extinguishing Device contains a specially formulated solid aerosol compound consisting primarily of strontium nitrate and potassium nitrate.

When activated:

The thermal trigger detects abnormal heat.
The aerosol compound undergoes an oxidation-reduction reaction.
Ultra-fine aerosol particles are released.
Active free radicals within the flame are neutralized.
The combustion chain reaction is interrupted.
The fire is extinguished before it can spread.

Unlike water, foam, or powder extinguishers, the aerosol particles can penetrate difficult-to-reach areas inside enclosed cabinets, providing total flooding fire suppression.

Typical Applications

Electrical Distribution Cabinets

Protect low-voltage and medium-voltage distribution panels from short circuits, overloads, and arc faults.

Industrial Control Panels

Safeguard PLC cabinets, automation systems, and machine control enclosures.

Battery Energy Storage Systems (BESS)

Provide automatic fire suppression for lithium battery cabinets and ESS systems.

Solar Power Systems

Ideal for photovoltaic combiner boxes, inverter cabinets, and DC switchgear.

EV Charging Stations

Protect charging piles and electrical compartments from overheating and electrical fires.

Server & Telecom Cabinets

Prevent costly downtime and equipment loss caused by electrical cabinet fires.

Installation Guide

Recommended Installation Position

Install the device at the top section of the enclosure where heat naturally accumulates during the early stages of a fire.

Installation Methods

3M VHB Adhesive Mounting
DIN Rail Mounting
Bracket Installation

Thermal Wire Placement

The heat-sensitive wire should be routed near:

Busbars
Circuit breakers
Cable terminals
Battery modules
High-current components

This ensures the fastest possible activation during abnormal temperature rise.
