A dryer for a compressed gas provided with a vessel with a drying agent and a drying zone-and a regeneration zone; at least one intermediate zone that, viewed in the direction of rotation of the drum, is situated between the regeneration zone and the drying zone and which is provided with a separate inlet and an outlet that is shared with or connected to the outlet of the regeneration zone; a tap-off pipe that branches off from the outlet of the drying zone and connects to the aforementioned separate inlet of the intermediate zone; one or more blowers in the tap-off pipe for effectuating an intermediate flow from the drying zone, where the dryer is configured such that the entire flow of gas to be dried supplied to the dryer is first guided through the regeneration zone.

Method for drying compressed gas using a dryer with pressure vessels. The method having the steps of guiding a first part of the gas to a cooler via a regulating valve, and of subsequently drying this first part of the gas in the drying pressure vessel; and of heating a second part of the gas so as to regenerate the regenerating pressure vessel. When the temperature in the regenerating pressure vessel rises above an upper limit value, the regulating valve will be gradually moved in the direction of the shut position and, when the temperature in the regenerating pressure vessel drops under a predetermined bottom limit, the regulating valve will be gradually moved in the direction of the entirely open position, which adjustment allows to set the compressed gas at a desired temperature.
