Will Cabinet Coolers cause condensation inside our control panels?

No, as the cold air produced by the Cabinet Cooler is introduced into the enclosure, it expands to atmospheric pressure and warms to the temperature of the enclosure. There is the potential for condensation only if humidity from ambient air is allowed into the panel. For this reason, it is imperative that all louvres and other openings are closed off. On initial start-up, the Cabinet Cooler will purge out the warm, moist air from inside the panel. As the cool air generated from the Cabinet Cooler enters the panel, it starts to pick up heat and the relative humidity drops. A continuously operating Cabinet Cooler will stabilise the relative humidity inside the panel at approximately 45%. We also recommend using a 5-micron filter separator to remove any condensate from the airline.
