Cabinet-type heptafluoropropane fire extinguishing device is a prefabricated system, which is produced in series. It is a pipe-free, portable, portable, automatic fire-fighting fire-fighting equipment with flexible and convenient installation and beautiful appearance. The fire extinguishing agent has no pipe network loss, high fire extinguishing efficiency, fast speed, and no pollution.


In the event of a fire, spraying fire extinguishing agents directly into the protected area is convenient and quick. This device does not have a bottle storage room. The gas storage bottle and the entire system are set in a protected area. It can be connected to the fire control center, or it can be equipped with a gas fire controller separately. For existing buildings that require an additional gas fire extinguishing system, a cabinet fire extinguishing device is more appropriate.


The working principle of this device is similar to that of an independent single-zone system, except that no pipeline is required. After starting, the fire extinguishing agent is sprayed directly to the area through a short section of pipe and nozzle to implement fire extinguishing.


Requirements for protective areas


1. The ambient temperature of the protection zone should not be lower than -10 ℃.


2. The fire resistance limit of the protective structure of the protective area and the doors and windows should not be lower than 0.5h; the fire resistance limit of the suspended ceiling should not be lower than 0.25h.


3. The allowable pressure of the protective structure of the protective zone under internal pressure should not be lower than 1.2kPa.


4. The enclosed area should be kept closed when extinguishing fire. The openings other than the pressure relief port and the fire dampers in the ventilators and ventilation ducts used in the protected area should be closed before heptafluoropropane is sprayed.
