Product Formation

Victaulic Standard Response concealed Sprinkler (93℃ K80) is a fire sprinkler device specially designed for high-temperature environments. It combines advanced thermal sensing technology with concealed installation features and is suitable for places with strict requirements for aesthetics and reliability.

The main body of the nozzle is made of a brass frame and a bronze splash pan, which have strong corrosion resistance and are suitable for damp or corrosive environments. A 5mm diameter glass ball (standard responsive type, RTI≥80 m½ · s½) is adopted. When the ambient temperature reaches 93℃, the glass ball breaks and triggers water spraying, covering a radius of approximately 1.8-3.6 meters, effectively controlling the initial fire.
