Abstract: A compressed gas dryer is provided with a drying zone and a regeneration zone, and a drum rotatable in the housing containing a drying agent that is transferred successively through the drying zone and the regeneration zone, whereby said regeneration zone comprises a first subzone having a first inlet to supply a first regeneration gas flow, and a second subzone having a second inlet to supply a second regeneration gas flow of which the relative humidity is lower compared to that of the first regeneration gas flow; and that an outlet of said drying zone is connected via a connection conduit to the second inlet of the second subzone.

Abstract: Device for compressing and drying gas includes a compressor and a dryer using a drying agent for drying gas connected thereto. The compressor includes two or more compressor elements with an inlet and an outlet which are connected together in series to form a first low-pressure stage. One or more subsequent high-pressure stages are each connected with their inlet to the outlet of a previous compressor element via a pressure pipe and an outlet pipe in which an after cooler is incorporated. The dryer has a drying section and a regeneration section. The drying section is filled with a drying agent for drying the gas and has an inlet connected to the outlet pipe of the compressor device, and an outlet that supplies compressed and dried gas. The regeneration section dries moist drying agent by a regeneration gas which is guided there via an inlet and an outlet with a regeneration pipe connected to the inlet.
