Abstract: The invention relates to a heat exchanger for a refrigerant dryer such as a compressed air refrigerant dryer comprising at least one first inflow surface element, past which a fluid to be dried such as compressed air can flow during operation of the heat exchanger, and comprising at least one second inflow surface element, past which a refrigerant fluid can flow as required during operation of the heat exchanger, wherein the first and second inflow surface elements are or can be coupled at least in some areas to at least one cold store chamber that is provided for filling with a cold accumulator medium, and wherein the first and/or second inflow surface element(s) (is) are connected to at least one heat transfer element which extends into the cold store chamber, e.g. penetrates the cold store chamber.

Abstract: An adsorption drying apparatus, in particular for drying a compressed gas, includes an adsorption chamber (11) having a plurality of adsorption conduits (101) containing an adsorption material (123), a first feeding line (106) and a first discharging line (109) disposed at a first end (111) of the adsorption chamber (11), and a second feeding line (108) and a second discharging line (107) disposed at a second end (112) of the adsorption chamber (11). The adsorption chamber (11) is rotatable with respect to the feeding and discharging lines (106, 107, 108, 109) so that the adsorption conduits may be fluidically connected in temporal alternation, wherein the gas is dried in a drying sector (102), and the adsorption material (123) is regenerated in the regeneration sector (103). The first feeding line (106) is configured such that the gas stream to be dried may be fed to the regeneration sector (103) as a full flow.

Abstract: A compressed air filter adapter for connecting a filter element (12) to a filter connection housing (13) includes a flow duct (21) enclosed by a wall (20) for compressed air, the flow duct (21) at a first end being delimited by a first opening (14), having an inner contour (142) defined by a first edge (141) and an outer contour (143), and at a second end by a second opening (15), having an inner contour (152) defined by a second edge (151) and an outer contour (153). The first opening (14) is provided for connection to a filter connection housing (13) and forms an opening cross-section (16), defined by the inner contour (142) of the first opening (14). The second opening (15) defines an opening on the filter side and forms a second opening cross-section (17), defined by the inner contour (152) of the second opening (15).
