The utility of the "Ventilation Plugs" can be listed as follows: <o: P>
? Prevention of pressure increase inside the enclosure. The pressure sensitive elements are not threatened. <o: P>
? Limiting of temperature increase by the air circulation. The temperature sensitive elements are not threatened. <o: P>
? Added flexibility for maintenance. In traditional units, when the enclosures are heated, generaly the dilated air goes out from the seals but can not return back when the device is colder. Because of the vacuum formed inside the enclosure, the gaskets are exposed to large pressure levels. In result, it is very difficult to open the covers for maintenance. Especially in "luminaires" it is obligatory to change the bulbs when the device is cold. The ventilation plugs in our system prevent these kind of limitations. <o: P>
? Prevention of accidental water suction into the system. During the cooling period, we know that there is air circulation from the outside to the inside. Hence, if the enclosure is wet from rain or due to other reasons, some water may be sucked inside the enclosure if there is no ventilation plug. <o: P>
? Prevention of exposure to hot, humid, compressed gases. There is always a level of humidity in the enclosure due to atmospheric conditions. Hence when the device is hot, all the components will be exposed to a hot, humid and compressed environment without the ventilation plug. <o: P>
<o: P>
To conclude, the ventilation plug can reduce and even fully eliminate the adverse effects of humidity in the environment. Water drops on the bottom of the enclosure are normal, but the inherent damage becomes insignificant due to the existence of a ventilation plug. <o: P>
