High-Capacity Aerosol Fire Suppression for Larger Enclosures
The High-Capacity Thermal Aerosol Fire Extinguishing Device is designed for automatic fire suppression in larger enclosed spaces where greater extinguishing agent capacity is required.
Typical applications include bus and commercial vehicle engine compartments, large electrical cabinets, battery enclosures, control panels and industrial machinery compartments.
When exposed to flame or the specified activation temperature, the device automatically releases fire-extinguishing aerosol to suppress an early-stage fire. No external power supply or manual operation is required.
Compared with lower-capacity models, this series uses a larger housing and higher extinguishing agent weight to provide greater aerosol discharge for larger protected spaces.
The series is available in 20 g, 30 g, 40 g, 50 g and 60 g models.
