Can a ventilation system be fitted inside an electrical enclosure?

Short answer

Yes, a ventilation system can be fitted inside an electrical enclosure, including as a retrofit to an existing installation. Our Air-Technology setup is integrated automatically in our AK range of distributors and is also available for other enclosures. It uses air exchangers that transport condensate out of the enclosure while allowing the interior air to mix constantly with the environmental air. Ventilation elements prevent condensation forming and building up, reduce the risk of overheating, and protect the electrical equipment within, meeting IP65 requirements.

Yes. Ventilation can be fitted inside our enclosures, and it can also be retrofitted to existing installations.

Ventilation systems play a crucial role in electrical enclosures. They prevent the formation and build-up of condensation as well as temperature increases within the structure. In this way, ventilation elements actively protect the electrical equipment within an enclosure from water and effectively meet IP65 requirements. They also reduce the risk of overheating, optimising the service life of the electrical equipment.

To avoid moisture and heat accumulation, we developed an innovative Air-Technology setup. This is automatically integrated in our AK range of distributors, but it is also available for other enclosures, including existing installations, where it can easily be retrofitted.

Our Air-Technology is composed of air exchangers that transport condensate out of the enclosure whilst also allowing the interior air to mix constantly with the environmental air. As a result, you can rely on a highly reliable and robust solution that combats moisture accumulation whilst maintaining an optimal internal temperature.
