In order to understand the advantages of these tools, it is first necessary to understand their meaning. Essentially, explosion-proof positive pressure cabinet equipment must have components and connectors that do not generate sparks or heat under normal or fault conditions, which may cause explosive gas ignition. Explosion proof certification is required in these environments. All objects with temperatures above zero emit thermal radiation, mostly in the form of infrared radiation (IR) or infrared light. The wavelength of IR is between 700 nanometers and 1 millimeter, placed between visible light and microwave radiation in the electromagnetic spectrum.
