By Heat-Sensitive Element

Fire sprinkler heads can be categorized by their heat-sensitive elements, mainly including glass bulb sprinkler heads and fusible element sprinkler heads. Glass bulb sprinkler heads use a heat-sensitive liquid-filled glass bulb for precise temperature activation, while fusible element sprinkler heads operate through the melting of heat-sensitive metal components.

Different sensing technologies provide various options for fire protection systems. We offer sprinkler heads with reliable thermal response, consistent activation performance and multiple temperature ratings to meet different application requirements.
