Thermal Aerosol Fire Extinguishing Device for Enclosed Spaces
The Compact Thermal Aerosol Fire Extinguishing Device is designed for early-stage fire suppression in enclosed and high-risk areas such as vehicle engine compartments, electrical boxes, battery packs, control panels and compressor compartments.
When the surrounding temperature reaches the activation threshold or the device is directly exposed to flame, it activates automatically and releases fire-extinguishing aerosol to suppress the fire rapidly. No external power supply or manual operation is required.
The housing is made of flame-retardant PA66, providing reliable structural protection and making the device suitable for installation in compact electrical and mechanical spaces.
Available in 10 g to 50 g models, the device can be selected according to the enclosure volume and fire protection requirements. It may be installed by adhesive mounting or guide-rail clip fixing depending on the application.
