During the warmer months, if you experience elevated relative humidity (RH), the dew point is elevated, too. Under these conditions, you must monitor and adjust your cooling water to keep it above the ambient dewpoint.
For example, if the temperature in your site is a steady 75°F and the RH is 40% or lower (line A), 55°F cooling water poses no condensation threat to your induction equipment because it is above the dew point.
But if the RH rises (July 2006 has seen some historically high temperatures and humidities in many parts of the world) to 50% (line B), 55°F cooling water may cause your equipment to experience internal condensation, which can result in equipment failure.
We recommend periodic monitoring of your cooling water temperature as a component of your Preventive Maintenance program, especially if your ambient conditions can present elevated RH.
Take steps to regulate the cooling water temperature for your induction heating system to ensure that it is kept above the dew point. The day's dewpoint can be obtained from your local weather service or (in the USA) from this website. You can select other countries from this site, too.
