Anti-Condensation in Electrical Enclosures


When conditions are humid or the temperature in an environment suddenly drops, the water held in the air around us cannot stay suspended as a gas, and must condense back into water. It does this on any cold surfaces it can find including car windows, grass, mirrors, etc. The temperature at which this happens is called the DEW POINT and the water that condenses is known as condensation (or dew). This same effect can cause problems with electrical equipment as condensation can occur inside enclosures and on sensitive equipment if they are not suitably protected.
