AFSS(Automatic Fire Sensing & Suppression System)


Automatic Fire Sensing & Suppression System


Safety and Reliability Approved. Fire Suppression performance Promised. 


Automatic Fire Sensing & Suppression System has the capability to automatically detect & extinguish fires and explosion in ground military vehicles.
It is very essential machinery to improve the survivability of military vehicles due to flash fires or explosions in combat vehicle that may be caused by fuel and shells during enemy attack.
It takes less than 0.25sec to detect & suppress fire, which will avoid any damage and protect crew members and the vehicle.
