The difference between explosion-proof positive pressure cabinet and explosion-proof distribution box

Explosion proof positive pressure cabinets and explosion-proof distribution boxes are all explosion-proof electrical equipment and can be used in flammable and explosive gas environments. Overall, their differences are not significant, but in some special situations, their differences will be reflected. For example, if a chemical plant has pollution source emissions and requires online monitoring and analysis by an online monitoring analyzer, and the site belongs to a flammable and explosive hazardous area, the analytical instrument cannot be exposed to work in this environment. Therefore, we can choose an explosion-proof positive pressure cabinet to put the analyzer inside the cabinet for work.

But we all know that explosion-proof distribution boxes are cheaper, why not choose explosion-proof distribution boxes? This brings us to the online analyzer we mentioned earlier. Regardless of the type of analyzer, it requires personnel to be able to operate and display its data. However, if the analyzer is placed in an explosion-proof distribution box with a display window, the data can be seen but cannot be operated. If the analyzer is directly placed on the surface of the explosion-proof distribution box, it can be operated, but this does not meet the explosion-proof requirements and is prone to accidents.

Why is an explosion-proof positive pressure cabinet sufficient? This brings us to the different explosion-proof forms of explosion-proof positive pressure cabinets and explosion-proof distribution boxes. The explosion-proof form of explosion-proof distribution boxes is explosion-proof, and all joint surfaces must be treated with explosion-proof measures. On the other hand, explosion-proof positive pressure cabinets belong to the positive pressure explosion-proof structure, which achieves explosion-proof requirements by maintaining a slight positive pressure inside the cabinet. The analyzer can be closely attached to the panel, which is different from the explosion-proof distribution box.

The explosion-proof effect of explosion-proof positive pressure cabinets and explosion-proof distribution boxes is mainly reflected in the explosion-proof form. Choose the explosion-proof equipment according to the desired function on site. Explosion proof positive pressure cabinets not only have stronger compatibility with components, but also have incomparable advantages over explosion-proof distribution boxes in terms of cooling internal components.

Each has its own advantages, depending on the buyer's choice.
