Abstract
Apparatus is described for decreasing the frost-free recapture time of a multi-pane glazed door such as is used on refrigerated display cabinets, by selectively heating the innermost pane when it is exposed to high relative humidity conditions. An electric current is passed through an optically transparent electrically conductive layer on the unexposed surface of the innermost pane. This heats the pane to a temperature above the dew point of the ambient air.
