The KEKX‑SG100 special horizontal‑launch fire extinguishing device integrates ultra‑fine dry powder and water‑based composite fire‑extinguishing agents. Each unit provides an effective fire‑extinguishing area of 30 ㎡, a fire‑extinguishing height of 4 m, and an effective fire‑extinguishing volume of 120 m³. It thoroughly breaks the operational limitations of conventional fire‑hose‑based fire‑fighting systems, improving fire‑suppression efficiency while effectively reducing operational risks.
