Abstract

What is described is a process and an installation for drying articles, in particular painted vehicle bodies, in which the articles are moved through a drying zone in which they are hardened in an inert-gas atmosphere. Inert gas is taken from the drying zone constantly or intermittently and is first of all conducted along a first face which is at a first temperature at which higher-boiling contaminants condense out. The condensate that forms in the process is discharged. After that, the inert gas which has been pre-cleaned in this way is conducted along at least one second face which is at a lower temperature than the first face. Lower-boiling contaminants are precipitated at this point. These condensates, too, are then discharged. This process and installation work more favorably, energy-wise, and with higher cleaning efficiency than known processes and installations of a similar type.
