Conveyor System Fire Protection - Hansentek

The general rule in fire protection systems for conveyors is to locate Ember Detector(s) upstream from a change in direction (transfer to another conveyor) or a dust producing process or storage point. Hence, once the ember is detected, it can be extinguished before it enters the next process where it can cause a potential explosion.
