Đầu phun Rapidrop -15mm (1/2”) Conventional, Pendent and Upright Sprinklers (4.18)

RD020 / RD021 Conventional, RD022 / RD023 Pendent and RD024 / RD025 Upright are Standard / Quick Response frangible glass bulb automatic sprinklers. They are CE Marked and LPCB approved standard orifice fire sprinklers for installation in fire sprinkler systems designed in accordance with standard installation rules, e.g. EN12845 or the requirements of the Authority Having Jurisdiction.
 
Conventional sprinklers produce a spherical water discharge pattern and the Pendent / Upright produce a hemispherical water distribution pattern below the deflector.In a fire condition the heat causes the fluid in the glass bulb to expand which shatters the glass and releases the spring seal assembly. Water flows from the orifice onto the sprinkler deflector which diffuses the water into a uniform spray pattern which extinguishes or controls the fire.
