Condensation The influence of humidity and temperature of the atmosphere may change the conditions of fabrication during different seasons signiﬁ cantly. As much as humidity condenses on a cool glass of beer, this can happen on Aluminium surfaces as well. The difference of temperature between air and metal and the humidity are the responsible parameters. The following table shows the dew points at different temperature differences and humidity in some examples. MIGAL.CO offers a dew point calculator for online calculation.
|(TAir - TMetal)||Relative humidity||(TAir - TMetal)||Relative humidity|
* Example: At a relative humidity of 70% water condenses on a metal surface with a temperature difference of 5° Celsius only. Condensation must be avoided in any case.
