Application Scenario: Cabinet-type heptafluoropropane fire extinguishing device is mainly suitable for the fire protection of small and medium-sized protective areas such as computer rooms, power distribution rooms, transformer rooms, archives and cultural relics reference rooms, small oil depots, and telecommunication centers.
:柜式七氟丙烷灭火装置又称无管网七氟丙烷灭火装置，是一种预制的，以全淹没方式灭火、独立成套、可移动的灭火设备，它具有安装方便、外形美观、灭火效率高、速度快等优点。 System composition : cabinet-type heptafluoropropane fire extinguishing device, also known as pipeless heptafluoropropane fire extinguishing device, is a prefabricated, fully submerged fire extinguishing, independent complete set, and movable fire extinguishing equipment. It has convenient installation, beautiful appearance, high fire extinguishing efficiency, Speed and other advantages. When a fire occurs, the device can automatically spray fire extinguishing agents directly into the protected area, which is convenient and quick. A protected area sets up a system, and several devices can be used in combination to protect a larger area. The cabinet-type heptafluoropropane fire extinguishing device has high fire extinguishing efficiency, which is convenient and fast. . This device can be used when a dedicated bottle group cannot be set in the building, or there is a bottle group, but the conveying distance is too long to meet the requirements of engineering design, or the protection area is inconvenient to install the system pipe network.
： 柜式七氟丙烷气体灭火装置不可片面追求大容积储瓶，否则无法确保10秒内喷放完毕，不能实施有效灭火。 System composition : The cabinet-type heptafluoropropane gas fire extinguishing device cannot one-sidedly pursue large-capacity storage bottles, otherwise it cannot ensure that the spray discharge is completed within 10 seconds, and effective fire suppression cannot be implemented. When using a large number of devices, a double bottle cabinet can be used. Cabinet-type heptafluoropropane gas fire extinguishing device uses "clean gas" heptafluoropropane (HFC-227ea) as fire extinguishing agent. The characteristics of heptafluoropropane: colorless, odorless, non-conductive, low toxicity, high fire extinguishing efficiency, does not pollute the protection object, especially does not have any damaging effect on the atmospheric ozone layer. Among the first-generation halon alternatives, heptafluoropropane has the best overall performance.
：柜式七氟丙烷灭火装置、气体灭火控制器、火灾探测器、声光报警器、放气指示灯、紧急启停按钮、外设电源等组成完整的自动灭火系统。 System composition : cabinet-type heptafluoropropane fire extinguishing device, gas fire extinguishing controller, fire detector, sound and light alarm, gas release indicator, emergency start and stop button, external power supply, etc. to form a complete automatic fire extinguishing system.

System application scenario
Heptafluoropropane gas cylinderThe wall thickness of the gas cylinder container used in the pipe network heptafluoropropane fire extinguishing system is about 2mm thicker than that of the same industry. The wall thickness and strength are high, and the risk of gas cylinder explosion is low. The service life is about 5 years longer than that of the same industry. Lower.
Pressure gaugeThe airtightness of the valve head is good, the pressure of the pressure gauge is stable, and the pressure drop rate is controlled at 0.02%. There is no frequent pressure drop, and it is avoided to be fined because the pressure gauge has no pressure during fire inspection. .
Bottle group fixed frameThe bottle frame fixed frame is made of square steel, and its structural strength is 3-5 times stronger than the angle steel used in the same industry. The pipe parts and components are all high-standard products that are resistant to high pressure.
HeptafluoropropaneHeptafluoropropane medicaments are never short of two pounds, 100% in line with the customer's order amount, to avoid legal liability caused by insufficient fire caused by the fire can not be effectively extinguished. .
