heat exchanger in which a vapour is deprived of its latent heat of vaporization and is changed to its liquid state, usually by cooling at constant pressure.

- Steam surface condenser – A gas-tight chamber that is fitted with heat-conductive tubes through which cooling water is circulated, and which is provided with means for continuously removing the condensed steam and noncondensable gases. The condensing process is accomplished by the heat transfer from the exhaust steam to the cooling water.
