Dear Bernard,

Yes: while enclosures are designed to cope with some temperature fluctuation, there are steps you can take to ensure your enclosure doesn’t get too hot all year round. Adequate ventilation is particularly important as it stops enclosures from overheating and allows moisture or pressure buildup to escape.

Enclosures protect electrical components from external hazards like dust and water, but when the air inside expands due to heating, pressure can increase, leading to damage and reduced protection. Vents allow this pressure to escape by equalizing natural heating and cooling without affecting protection levels.

Even when enclosures aren’t exposed to ambient temperature changes the components inside can generate heat. Releasing this build up is important to maintain safe operating conditions and to avoid condensation of trapped moisture. While good air circulation reduces humidity inside the enclosure, it’s important to ensure that vents enable flow without letting potential hazards like dust in.

Our ventilation range includes IP44 and IP65 options so you can choose the level of protection that’s best for your enclosure. Our seals and ventilation elements are designed for vertical installation in enclosure walls.
