Today we are going to show you the different types of cabinet heptafluoropropane and the places where it should be used.
The cabinet heptafluoropropane fire extinguishing device is integrated by the extinguishant storage container components, injection pipelines, nozzles, electromagnetic drive devices, etc., and is connected with the automatic fire alarm controller to realize automatic control and measurement and fire extinguishing. Since the fire extinguishing agent storage bottle is placed in the cabinet, for small protection areas of different sizes, select single bottle groups with different volumes for protection, which can reduce the floor area; The nozzle adopts multi hole type, which can make the fire extinguishing agent fill the whole protection area quickly and evenly; And the device, like the hanging fire extinguishing device, has the characteristics of simple construction and installation and small engineering investment, so it is very popular with customers in practical application.
We know that different protected areas have different design concentrations, such as 10% for archives, which requires 0.81kg of heptafluoropropane per square meter. In addition, it is necessary to calculate the appropriate reserved amount. Some customers will calculate the total drug dose according to the volume of the protected area, and then choose the appropriate equipment by themselves. At this time, there may be "selection difficulty", because the cabinet type heptafluoropropane fire extinguishing device alone has four device specifications: single cabinet single nozzle, single cabinet double nozzle, double cabinet single nozzle, double cabinet double nozzle, and the steel cylinder capacity has seven specifications: 40L, 70L, 90L, 100L, 120L, 150L, and 180L.
All the four schemes can meet the total drug dose demand of the protected area, but to choose a suitable scheme, it needs to be carried out in combination with the internal situation of the protected area.
For example, when there are many equipment in the protected area and there is not much space to place cabinet heptafluoropropane fire extinguishing devices, the scheme with a relatively small number of fire extinguishing devices is obviously more suitable. If the equipment is small and relatively scattered, selecting multiple fire extinguishing devices will be more conducive to the safety of the equipment.
In addition, the cabinet heptafluoropropane fire extinguishing device has a safe distance from the operation surface, and the distance from the operation surface to the wall or between the two operation surfaces should not be less than 1m, so this is also something to consider when choosing a scheme.
