In electrical panels, temperature changes and condensation phenomena are among the main causes of malfunctioning of electrical and electronic equipment. In addition to a correct ventilation, it’s therefore necessary to provide anti-condensation heaters, to raise the temperature of the panel up avoiding the so-called dew point, over which is reduced the risk of condensation.
Why does condensation form inside enclosures?
Electrical and electronic components inside the electrical panel generate heat during their operation: when the temperature rises, water particles, naturally contained in the air, especially in the humid areas, are at their gaseous state, but when temperature drops and in contact with a colder surface (such as the walls of the panel, for example), the vapor condenses back to its liquid state in form of drops. It’s the same phenomenon that can be observed on a glass, blowing on it.
What are the cases in which anti-condensation heaters should be installed?
During the winter, in areas affected by a strong temperature excursion between night and day (as in hot countries or desert), or in humid countries, the risk of condensation is much higher!
Therefore, it’s important to maintain ideal climatic conditions to ensure a long life for the components installed in the electrical panel, considering the use of an anti-condensation heater already from the production / installation phase.
The Fucsis H series anti-condensation heaters from Fandis
The electric resistances installed in the Fandis’ Fucsis H-series anti-condensation heaters guarantee a temperature rising inside the electrical panel, preventing dew point and condensation from forming, protecting electrical and electronic components. Fandis anti-condensation heaters allow the maintenance of an ideal internal temperature, working in combination with a thermostat or hygrostat to constantly monitor temperature and humidity levels. They are also available with built-in forced convection fan, to ensure a proper air circulation and a more accurate distribution of heat in the enclosure and with Touch Safe plastic protection, avoiding burns in case of accidental contact.
