It can be matched with various types of structures and projects of different sizes, in line with the design concept of the latest pipeline project, which is the optimal distance of 4 to 8 meters between two suspended fire extinguishing devices. The total cost of the project is the lowest and the most economical. If 12 and 14Kg specifications are used instead of 8 and 10Kg, the total cost and maintenance management cost can be reduced by more than 30%. When designing with Lidada, it is necessary to focus on the three specifications of 10, 12 and 14Kg and the design concept of the optimal spacing of 4 to 8 meters. This will greatly reduce the competition.
