There are two main potential thermal problems inside the enclosure:
Humidity, or water condensation.
Overheating can occur inside the enclosure due to internal heat dissipation or external heat sources.
Overheating of the equipment will lead to reduced component lifetime and increased risk of breakdowns.
Eldon offers a wide range of cooling solutions to avoid harmful overheating:
Air conditioners, an efficient cooling solution which does not require the ambient air temperature to be lower than the desired temperature inside the enclosure. An additional advantage is that air conditioners will dehumidify the air inside the enclosure, preventing condensation;
Vortex coolers, particularly suitable in applications where the working temperature is very high and other cooling solutions are impossible due to their maximum working temperature;
Heat exchangers, such as air-water types, are perfect when high cooling capacity is needed and fresh water is already available;
Filter fans constitute a cost-effective cooling solution with easy assembly and are used in all control panels where the ambient conditions are not a constraint.
One of the greatest risks in an electrical enclosure is water condensation and high humidity which may reduce the lifetime of the electronic equipment.
Water condensation will occur if the temperature falls below the dew point. Eldon offers a wide range of heaters to increase the air temperature inside enclosures:
Small heaters, for small panels not requiring high heating capacity;
Medium and big heaters, for large enclosures where the heat generated is not too high, but where there is a risk of condensation due to temperature variations during day and night;
Fan heaters, to ensure even heat distribution in large enclosures where there is not enough natural air distribution.
