Product Formation
This sprinkler head features a pendant (ceiling-mounted) design, making it ideal for spaces with ceilings (e.g., retail stores, office buildings, small warehouses) where downward water spray ensures even coverage of fire-prone areas. Its core trigger component is a fusible alloy—a low-melting-point material that melts precisely at 74℃, avoiding false activations in normal ambient conditions (e.g., mild temperature fluctuations) while responding quickly to rising fire heat. With a K80 flow coefficient, it delivers steady water output under standard pressure (5–50 bar), sufficient to control small-to-medium fires in its coverage range. Typically crafted from brass or stainless steel, it resists corrosion and daily wear; its 1/2"–1" BSPT size also fits common pipeline systems, enabling easy integration into existing fire protection setups.
