These heaters ensure that the temperature inside electrical [...] always a proportion of dissolved water. Depending on the temperature, the air can absorb a larger or smaller amount of water. If the temperature drops e.g. due to day/night change, there is a risk of c [...] tunnel control. These heaters ensure that the temperature inside electrical enclosures does not fall below the so-called dew-point. The dew-point is the temperature that moist air has to drop to – by unchanged
