Abstract: A device for chill-drying a gas comprising a gas/gas heat-exchanger and a gas/cooling medium heat-exchanger located within a pressure vessel such that the heat-exchangers define channels between themselves and the walls of the vessel, which channels connect a gas outlet at the bottom of the gas/gas heat-exchanger with a gas inlet at the top of the gas/cooling medium heat-exchanger. The pressure vessel is cylindrical and the gas/gas heat-exchanger has a curved surface lying against the inner surface of the pressure vessel, and a planar surface abutting against the gas/cooling medium heat exchanger which has a rectangular cross-section and its corners remote from the gas/gas heat exchanger abutting against the walls of the pressure vessel.
