Perfluorohexanone pipe network fire extinguishing system uses perfluorohexanone fire extinguishing agent as a fire extinguishing medium, and provides different types of fire extinguishing agent storage tanks according to different sizes of protection spaces. The pressure capacity of the newly developed pipe network fire extinguishing system of our company can reach 3.45MPa. Under this pressure, the fire extinguishing system can use a smaller pipe diameter to transmit a longer distance, and can use less fire extinguishing agent in the same protection zone . It also includes standard monitoring components such as integrated pressure switches, pressure gauges and gauge guards, etc., enabling intelligent monitoring of fire suppression.
