The most commonly used gas fire extinguishing system is FM 200 heptafluoropropane.FM200 fire extinguishing devices are suitable for computer rooms, archives, airport control rooms, bank vaults, libraries, computer rooms and other occasions. There are three types of heptafluoropropane fire extinguishing devices known in the market: cabinet type heptafluoropropane fire extinguishing device, pipe network type heptafluoropropane fire extinguishing system, and suspended heptafluoropropane fire extinguishing device. Which product is more suitable for you?
cabinet-type HFC-227EA gas fire extinguishing system:
The cabinet-type FM 200 gas fire extinguishing device does not have a storage room. The gas storage bottle and the entire system are set in the protection area. It is suitable for small space protection areas such as computer rooms, archives, valuables warehouses, and telecommunication centers. Combination of counter-cabinet-type heptafluoropropane gas fire extinguishing device can also protect the protection area of larger space. This device can be connected with the fire control center, or it can be equipped with an automatic fire extinguishing controller separately to form its own system, giving users convenient and flexible choices. For existing buildings, it is necessary to add a fire extinguishing system. It is more appropriate to choose a cabinet-type heptafluoropropane fire extinguishing device
Pipe network type FM200 fire extinguishing system
Pipe network type heptafluoropropane fire extinguishing system: it is composed of heptafluoropropane steel cylinder, container valve, nitrogen cylinder group, electromagnetic drive device, selection valve, one-way valve, header, connecting pipe, pressure signal device, nozzle and other components. The system is at 20℃ The storage pressure is 4.2MPa, and the maximum working pressure (at 50°C) is 5.3MPa. Need to set up a dedicated cylinder room. The gas fire extinguishing agent storage bottle of the pipe network heptafluoropropane fire extinguishing system is usually placed in a special steel cylinder room and connected by a pipeline. When a fire occurs, the fire extinguishing agent is transported to the protection area that needs to be extinguished by the pipeline, and sprayed and extinguished through the nozzle.
Suspended FM200 automatic fire extinguisher
Suspended heptafluoropropane gas fire extinguishing device (electromagnetic type) is composed of fire extinguishing agent storage bottle, container valve, nozzle, electromagnetic drive device, signal feedback device, suspension bracket, etc. It does not need to install fire extinguishing agent delivery pipeline or special storage bottle. In the room, it adopts hanging or wall-mounted installation. When a fire occurs, the fire extinguishing agent is sprayed directly to the protection area. The extinguishing agent has no pipeline loss, and the fire extinguishing speed is faster and more efficient. The device has automatic and manual start modes
In summary, the cabinet-type heptafluoropropane does not require a special steel cylinder room, but can be set in the protection area, which saves the cost of pipe network fittings. Relatively small space, the construction cost of cabinet-type heptafluoropropane is lower, and the construction cost is relatively large In terms of space, the cost of suspended heptafluoropropane and pipe network heptafluoropropane is relatively low. As for which heptafluoropropane fire extinguishing device to choose in the protection area, professional engineers need to choose according to the protection area and the protection object.
