1. A device for reducing the relative humidity of a flowing gas, said flowing gas having a temperature warmer than ambient atmosphere in which said device is disposed, said device comprising:

  • a container having a top end and a bottom end with a cavity with an interior wall therebetween, and an inlet for flowing gas containing water vapor disposed at said top end;

    an element consisting of heat conducting material having a through-channel therein disposed in said cavity of said container, said through-channel of said element having an opening disposed in said cavity spaced from said bottom end of said container, and having an opening forming an outlet for said flowing gas disposed at said top end of said container, said container and said element forming, in combination, means for dehumidifying and reducing the temperature of said flowing gas entering said container through said inlet by heat exchange between said flowing gas and an upper portion of said element for producing cooler flowing gas and thereby warming said upper portion of said element as said cooler flowing gas flows in a flow path from said top end of said container through said cavity to said bottom end of said container and into said through-channel and by condensing water, in said flow path, from said cooler flowing gas on said interior wall of said cavity, and by re-heating said cooler flowing gas exiting said container through the warmed upper portion of said through-channel and said outlet; and

    means for thermally insulating said element from said container.
