The A|ZSTWC medium-speed water mist nozzle sprays small water droplets at low speeds. Its low-penetration spray can effectively extinguish ignited oil or control dangerous situations involving strong explosions. It can also be used to cool volatile liquids or chemical containers exposed to fire. It is commonly used as a sprinkler head in deluge systems to provide protection at the required angle. The nozzle's design parameters include K-factors of 27, 43, and 84; thread specification R1/2 (15mm); atomization angle of 80, 100, or 140 degrees; maximum operating pressure of 1.2MPa; and minimum operating pressure of 0.05MPa. The installation parameters indicate the installation position as "--". Manufacturer models include R20, R30, and R60, corresponding to the national standard model ZSTWC. The nozzle height is 67mm. The K43 (R30) model has CCC certification; other CCC certifications are available based on project requirements.
Water mist nozzles are ceiling-mounted fire extinguishing devices used for fire suppression. Their design is based on the shape of the product shown in the diagram.
