The carbon dioxide fire extinguishing agent of high-pressure carbon dioxide fire extinguishing device is a non-conductive, non secondary pollution, non water damage, inexpensive and effective fire extinguishing agent. When sprayed, it rapidly expands in volume and absorbs a large amount of heat, which can reduce the temperature at the fire scene and dilute the oxygen concentration in the protected space to achieve suffocation fire extinguishing effect. It can be used to extinguish various surface fires of flammable and combustible liquids and solid materials, as well as shallow and deep fires, and gas fires where the gas source can be cut off before extinguishing.

Due to the suffocating effect of carbon dioxide on humans, carbon dioxide fire extinguishing equipment is not suitable for manned places. If installed and used in places where people often work, appropriate protective measures should be taken to ensure the safety of personnel.
