Product Formation
Concealed design
The main body of the nozzle is hidden in the ceiling, with only the decorative cover plate exposed. In case of fire, the cover plate automatically falls off, and the nozzle hangs down to spray water.
Adjustable installation depth (up to 13mm), suitable for different ceiling structures (such as gypsum board, metal ceiling).
Rapid response mechanism
It adopts 3mm diameter glass bulbs, with a response time index (RTI) of ≤50 (m · s)⁰ · ⁵, which is 50% faster than standard nozzles and can quickly control the fire in the early stage of a fire.
The hemispherical splash pan design ensures uniform water spraying, with a coverage radius of approximately 3.7 meters, effectively suppressing the spread of fire.
Materials and Processes
The brass frame and bronze splash pan have strong corrosion resistance and are suitable for damp or slightly corrosive environments.
KEY WORDS：The surface can be selected with chrome plating, white polyester paint or black coating to match different decoration styles.
