The explosion-proof cabinet that comes with the exhaust gas treatment system is located on the top of Owner A’s Class A factory building; is it necessary to provide positive pressure ventilation for this explosion-proof control cabinet? What about the self-control touch screen outside? Do the staff need to operate the touch screen? If positive pressure ventilation is not used for the control cabinet, how can it be fully sealed? How can it dissipate heat if everything is sealed?
In accordance with the safety requirements for explosion-proof equipment, the interior of the explosion-proof cabinet should have a positive or negative pressure environment to prevent sparks from being generated or explosions from occurring during the operation of the equipment. Therefore, it is recommended that when the explosion-proof cabinet included in the exhaust gas treatment system is placed on the roof of the owner’s Class A factory building, positive pressure ventilation should be implemented to ensure the safety of the environment inside the cabinet. .
