  • Condensation in Switchgear and Anti-Condensation Heaters

    Condensation or dew occurs when the temperature of still air falls to the point the air can no longer hold the water vapor suspended in it as a gas. The resulting liquid that condenses combines with dust and other contaminates. When condensation occurs in switchgear there are very few surfaces where the result is not detrimental.
