Abstract: The invention relates to a method for coating a metal strip with a coating containing a solvent and for drying and/or cross-linking said coating. Accordingly, the metal strip is provided with the coating in an inner chamber of a coating device. The coated metal strip is conducted through a drying unit and in an inner chamber of the latter is exposed to a form of energy by at least one radiation source that is cooled by a cooling gas, said form of energy being converted to heat in the coating and/or the metal strip. The cooling gas that is supplied to the radiation source flows through the latter, absorbs the waste heat from said source and is then conducted into the inner chamber of the drying unit, thus saving energy and gas. The invention also relates to an installation that is suitable for carrying out said method.
