1. A hazardous location enclosure system comprising:

  • a hazardous location enclosure comprising at least one wall forming a cavity, wherein the at least one wall is designed to contain an explosion that originates within the cavity, wherein the at least one wall forms at least one joint, wherein the at least one joint comprises at least two surfaces of the at least one wall that meet and provide a path, from the cavity to outside the hazardous location enclosure, wherein the at least one joint allows gases from within the cavity during the explosion to escape across the at least one joint of the enclosure and cool as the gases exit the cavity;

    a temperature-sensitive component positioned within the cavity;

    a measuring device that measures a temperature within the cavity of the hazardous location enclosure;

    a climate control device configured to change the temperature within the cavity; and

    a controller operatively coupled to the climate control device, the temperature-sensitive component, and the measuring device, wherein the controller operates the climate control device to change the temperature within the cavity of the hazardous location enclosure when the temperature, as measured by the measuring device, falls outside an operating range of temperatures,wherein operating the climate control device brings the temperature within the operating range of temperatures and thereby reduces a risk of the explosion originating within the cavity of the hazardous location enclosure,wherein the controller alters an operation of the temperature-sensitive component when the temperature within the cavity is outside the operating range of temperatures.
