Compressor installation (1) with a compressor element (2), with an outlet (9) with an outlet line (8), and with a dryer (2), that is provided with a drying section (14) and a regeneration section (15), wherein the drying section (14) is provided with a first inlet (16a) and a first outlet (16b), wherein the first inlet (16a) is connected to the outlet line (8), wherein the regeneration section (15) is provided with a second inlet (17a) and a second outlet (17b), wherein a regeneration line (18) is provided between the second inlet (17a) and a first point (19) of the outlet line (8), wherein at the second outlet (17b) a return line (20) is connected that connects the second outlet (17b) to a second point (21) on the outlet line (8) downstream of the first point (19), characterized in that, in the return line (20), a primary portion (27) of a heat exchanger (28) is incorporated, wherein a secondary portion (29) of the heat exchanger (28) is incorporated in an oil circuit (10) of the compressor element.

Method for controlling an air-cooled device (1) for compressing a gas, which device comprises at least one element (2) for compressing the gas, at least one air-cooled cooler (9, 12) for cooling a fluid in the device (1) and two or more fans (10, 13), at least one of the fans (10, 13) being an adjustable-speed fan (13) for generating a flow of cooling air for cooling the air-cooled cooler (9, 12), characterized in that, when the air-cooled cooler (9, 12) does not need to cool, the method consists of controlling the speed of the adjustable-speed fan (13) to a minimum required speed in order to avoid at least a backflow of cooling air traveling in a direction opposite to the flow.

Compressor device (1) comprising a compressor element (9) which is at a fluid duct outlet (26) provided with an adapter of acoustic impedance (10) which comprises an adapter inlet duct (27) and an adapter outlet duct (28) interconnected by means of an adapter intermediate duct part (29) which encloses at least one expansion chamber (30), wherein a maximum opening (32) with an equivalent diameter (C) of the adapter intermediate duct part (29) is substantially larger than a minimum opening (31) of the adapter inlet duct (27) with an equivalent diameter (B).

Dryer for compressed gas, comprising a pressure vessel containing a drying zone and a regeneration zone, a drum within the rotation symmetrical part, equipped with a regenerable drying agent; driving means for rotating the aforementioned drum so that the drying agent is successively moved through the drying zone and the regeneration zone, an inlet for the supply of the compressed air to be dried to the drying zone, an outlet for the removal of the dried compressed gas, and a first connection line for branching off of a partial stream of the dried compressed gas and transfer of this partial stream to the regeneration zone. The drying zone is on outlet side is subdivided using a divider into a first outlet zone with which the outlet is connected for the dried compressed gas, and a second outlet zone with which the first connection line is connected.
