As a result of warming, from either the sun’s radiation or the enclosed electronics, pressure differences develop between the housing and its surrounding environment, which result in the transfer of air from one to the other. Air drawn into the housing carries moisture, which condenses when the temperature drops below the dew point. The water which is now trapped in the enclosure can lead to corrosion and equipment failures.
To prevent pressure differences, high humidity and condensation of water in the housing, constant balancing of pressure and Exchange of air is needed. The use of AGRO pressure balance elements in electrical and electronics housings allows efficient pressure balance and ventilation, and if necessary, drainage.
A new pressure balance element for increased safety Ex e II with membrane is now available.
