How to fight dust in electrical enclosures

Dust deposits inside the electrical panel are among the environmental factors that can contribute to wear out internal components, shortening their operating life and causing breakdowns and service interruptions. What solutions can be adopted to combat dust?

Dust and ventilation

Dust and dirt accumulate on the electrical contacts and on the enclosure walls and, in addition to being unsightly, they can cause problems with the electrical connections. At the same time, however, the electrical panels need good ventilation, to avoid overheating or condensation and to keep the electrical circuits and devices in general efficient.

The rules to fight dust and ensure proper ventilation

Here are a series of useful tips to ensure correct ventilation of the electrical panel, limiting the damage caused by the accumulation of dust:

1. Check the correct insulation of the panel.
2. Calculate the thermal balance to ensure the optimal internal temperature.
3. Install components on the walls of the panel, such as filter fans, roof exhaust units, cooling systems, which have an adequate IP protection rating according to the conditions of the work environment.
4. Install filter fans to prevent dust from entering.
5. Use in ventilation systems of suitable filter media.
6. Clean and replace the filter mats regularly.
7. Use predictive maintenance devices.

Fandis offers a range of solutions for ventilation and cooling with protection levels suitable for different applications and compliant with CEI regulations, which use filter media with a high capacity to retain dust (G3, G4).

In addition, as we listed, another strategy that can certainly improve the management and efficiency of the enclosure is predictive or preventive maintenance on the machine.

Predictive maintenance and Sensis

For this reason, Fandis has developed Sensis, an IIoT device that detects useful events relating to risks on components, such as peak values ​​or exceeding critical thresholds or opening the cabinet door, records the time, the date and duration over time allowing to trace and combine any information for diagnostic purposes.
