Total flooding, differing from target or local extinguishment. It means wherever the fire happens in the protection zone, it can be put out after discharge. Because the dosage of extinguishing agent is designed for the whole protection zone.  

  The cabinet fire extinguisher is stored in the data room, convenient, efficient and safe Advantage 1. Heptafluoropropane is a gaseous fire extinguishing agent, which has no residue, is not conductive, and generally does not cause secondary pollution (compared with the ashen face of dry powder fire extinguishers after use). It is a good fire extinguishing agent for extinguishing electronic equipment, precision instruments and equipment, valuable instruments and archives, and other paper, silk or magnetic media material information carriers; 2. Within the designed fire extinguishing concentration (not less than 1.3 times of the fire extinguishing concentration), there is basically no adverse effect on human body (IG541 and carbon dioxide are toxic under the fire extinguishing concentration), and can be used in places where people stay (carbon dioxide fire extinguishing system is not allowed); 3. During the fire extinguishing process, the fire extinguishing speed is faster than that of carbon dioxide and IG541, which are the same gas extinguishing agents, and the fire extinguishing concentration and inerting concentration are lower than that of carbon dioxide and IG541. Therefore, for the same fire, the number of steel cylinders required for the gas fire extinguishing system is small, the floor space is small, and the layout requirements are low. The cabinet fire extinguishing system can be used for flexible installation (compared with IG541 and carbon dioxide fire extinguishing system, which require more steel cylinders to provide sufficient fire extinguishing capacity). 4.The fire extinguishing time of heptafluoropropane is generally completed within 1min, and there is no re-combustion after completion (asphyxiant fire extinguishing agent is prone to re-combustion). Application Electronic computer room, a data processing center, telecommunications facilities, process control, expensive medical equipment, industrial equipment, library, museum and art gallery, clean room, anechoic chamber, emergency power facilities, flammable liquid storage area, etc. The place where the fire is easy to happen, like paint-spraying production line, aging-electrical equipment, rolling machine, printing machine, oil switch, oil immersed transformer, melt impregnating tank, tank, large generators, drying equipment, cement pro duction process of pulverized coal, and the ship's engine room, cargo hold, etc.
