Cabinet Gas Fire Extinguishing DevicesDescription
Product Overview The Cabinet-Type Heptafluoropropane Gas Fire Extinguishing Device (Single Cylinder Bank) is a pre-engineered fire suppression system manufactured by Jiangxi Jianhao Fire Protection Equipment Co., Ltd. Heptafluoropropane (HFC‑227ea) is a colorless, odorless, electrically non‑conductive gas with zero ozone depletion potential and no secondary pollution. When a fire occurs, heat and smoke detectors send signals to the fire alarm control panel; after logic analysis, the panel issues audible/visual alarms, closes interlocked equipment, and after a preset delay, activates the solenoid actuator to open the container valve and discharge the agent. A manual emergency button is also provided for mechanical manual operation in critical situations. Key Features Complete product range with aesthetic appearance. Direct installation in the protected area – no dedicated cylinder storage room needed. Simple construction and installation with low project investment. Application Scope Computer rooms, telecommunications centers, electrical rooms, transformer rooms, archives, record rooms, valuable item storage, oil storage rooms, and other small‑space protected areas.
