The temperature control system includes a temperature control device that includes a pipe coil thermally connected to at least one of the walls of the housing. Optionally
An explosion protection housing constructed according to an explosion protection requirement having a temperature control system. The temperature control system includes a temperature control device that includes a pipe coil thermally connected to at least one of the walls of the housing. Optionally, temperature control fluid is directed through the pipe coil by means of circulating pump in order to increase or decrease the temperature of the housing, depending upon the explosion protection requirements.

1. An ignition protection housing assembly, comprising: an external casing having a plurality of solid walls that define an internal compartment having an open side, and a cover disposed along the open side to enclose the internal compartment, wherein an air gap is defined along an interface between the cover and the walls of the casing, the air gap being configured to have a dimension that inhibits ignition flashover between the internal compartment and the environment,a temperature sensor thermally and rigidly connected to one of the plurality of walls disposed to measure, and provide information indicative of, a temperature of the casing wall to which the temperature sensor is connected to a control device; anda temperature altering device thermally connected to one of the plurality of walls and operating to change a temperature of the casing by conducting heat to or away from the plurality of walls in response to commands provided by the control device;wherein the control device selectively activates and deactivates the temperature altering device for heating or cooling the casing by conductive heat transfer in response to temperatures determined by the temperature sensor. 2. The ignition protection housing of claim 1, wherein said temperature altering device is a cooling device for cooling the casing in response to activation by the control device. 3. The ignition protection housing of claim 1, wherein said temperature altering device is a heating device for heating the casing in response to activation by the control device. 4. The ignition protection housing of claim 1, wherein said temperature sensor is thermally connected to one of the casing walls without an air gap there between. 5. The ignition protection housing of claim 1, wherein said temperature sensor is supported in separated relation to the casing walls. 6. The ignition protection housing of claim 1, wherein the temperature altering device is connected without an air gap to an exterior surface of one of the casing walls. 7. The ignition protection housing of claim 1, wherein the temperature altering device includes a component located within the internal compartment of the casing. 8. The ignition protection housing of claim 1, wherein the temperature altering device is located in part within the internal compartment of the casing in separated relation to the walls thereof. 9. The ignition protection housing of claim 1, wherein the temperature altering device includes a plurality of tubular-shaped lines through which heat transfer fluid is transmitted, and wherein heat is added or removed from the casing by conduction between the casing, the tubular-shaped lines and the heat transfer fluid. 10. The ignition protection housing of claim 1, wherein the temperature altering device includes an electrical heating coil. 11. The ignition protection housing of claim 1, wherein the temperature altering device is an induction heater. 12. The ignition protection housing of claim 1, wherein the casing is constructed according to an ignition protection category. 13. The ignition protection housing of claim 12, wherein the casing is constructed in accordance with one of a “pressure-resistant encapsulation,” “increased safety,” “sand encapsulation,” or “oil encapsulation” in ignition protection category. 14. The ignition protection housing of claim 1, wherein the temperature altering device includes a heat exchanger connected directly to one of the walls of the casing. 15. A method for controlling a temperature of an explosion protection housing, comprising: providing the explosion protection housing, the explosion protection housing including an external casing with five side walls that define an interior space with an opening, and a cover connected to the side walls and disposed to close the opening such that interior space is enclosed, wherein the five side walls and the cover are made from a solid, plate metal material, wherein an air gap is formed between the sidewalls and the cover, the air gap being sufficient to arrest a flashover between the interior space and its environment;providing a temperature altering device that is associated with the casing, the temperature altering device being connected to one of the five side walls such that heat may be transferred via conduction between the temperature altering device and the one of the five side walls that the temperature altering device is connected to;sensing a temperature of the interior space of the casing, and;controlling operation of the temperature altering device as a function of the temperature measured by the sensing device for adding or removing heat via conduction between the temperature altering device and the casing for maintaining the temperature of the casing within a preferred range. 16. The method of claim 15, wherein the method further comprises mounting a component of the temperature altering device on an exterior surface of one of the side walls of the casing, and heating or cooling the wall, and thus the casing, as a function of temperature measured by the temperature sensor. 17. The method of claim 15, further comprising mounting a component of the temperature altering device within the interior space of the casing directly onto a wall of the casing for heating or cooling the casing as a function of the temperature measured by the temperature sensor.
