## Overview

This self-triggering thermal aerosol fire extinguishing device from Onaweno delivers rapid, automatic fire suppression by isolating oxygen and absorbing heat.

Ideal for proactive fire prevention in modern, tech-driven environments.

## Description

This product belongs to the thermal aerosol automatic fire extinguishing device (S type), and the fire extinguishing mechanism is as follows: 1. 【Isolation of oxygen】 Aerosol particles form a thick covering layer around the fire source, effectively isolating the flame from the surrounding air, depriving the flame of the oxygen necessary for combustion, thereby inhibiting the continued burning of the flame. 2.【Heat absorption】 When the aerosol is released, it absorbs a large amount of heat, reduces the temperature of the fire scene, and further weakens the burning ability of the flame. 3. 【Reduce oxygen concentration】 N2 and CO2 in the fire extinguishing aerosol can reduce the oxygen concentration in the combustion, further assisting in delaying the fire. 【Summary】: Aerosol fire extinguishers are self-trigger fire extinguishers, which are widely used in unattended protective equipment, such as distribution cabinets, new energy vehicle battery interiors, energy storage equipment, old car batteries, modified car interiors, etc. as auxiliary equipment for extinguishing or delaying fires. 【Warning】: This product is limited to closed/semi-enclosed environments and is used as a small fire extinguishing environment. It can be used to extinguish or delay the fire to gain rescue time, and can be used in conjunction with other large fire extinguishing equipment for joint protection.
