In addition to the various environmental infiltration factors such as water, dust and oil, corrosion can also have a detrimental effect on the electrical panel. Corrosion could in fact lead to a constant need for maintenance, malfunctions and… costly downtime! This is why it’s really important to plan and carefully evaluate the relevant factors when designing an enclosure, especially regarding temperature variations.
Temperature, condensation and corrosion in the electrical panel
The temperature, in fact, must be checked and maintained within certain levels to avoid a negative affection on electrical and electronic devices operations. The difference between the load temperature, derived from the heat generated by the active devices or the sun, and the temperature of the environment surrounding the panel, could generate condensation and potentially cause corrosion inside the cabinet and in the electronic components.
How to avoid or limit condensation and corrosion risk?
In order to guarantee constant operating safety, especially during machine downtime, night-time closures or in particularly cold environments, it’s advisable to install one or more Fandis Fucsis H series anti-condensation heaters, which guarantee a rapid and uniform heating, reducing humidity and keeping the temperature inside the panel constant. Anti-condensation heaters can be controlled by a thermostat or hygrostat and bring the temperature back to a safe operating level above the dew point, avoiding the risk of corrosion.
Corrosion in outdoor electrical enclosures
For applications in outdoor corrosive environments, with high levels of salt, chemicals or humidity, it’s important to choose products with materials capable of withstanding such hostile conditions. In these cases, for example, mild steel can easily rust. The Seifert Type 4X cooling units and stainless steel AISI 316 are able to withstand humid environments exposed to the elements and last over time.
A correct calculation of the thermal balance to limit the corrosive phenomena
To avoid the under or overdimensioning of the electrical panel with consequences on the operative efficiency of the devices and components installed in it, a study on the correct sizing of the thermal balance is advisable. You can find more information in our #whitepaper.
