Abstract: Drying device including a drying medium with a predetermined number of drying segments which extend adjacently of each other and are associated with at least one opening at each of a first connecting end and a second connecting end, wherein the predetermined number is greater than six and wherein each connecting end includes first and second complementary concentric elements which are rotatable relative to each other round an axis. The openings are provided in the first concentric elements along a rotation ring around the axis. The second concentric elements each delimit at least two channels which open at the position of said rotation ring, so that corresponding channels of the first and second connecting end are connected to each other via the openings and the drying segments in order to allow a first airflow and a second airflow through the drying device.

Abstract: Methods, systems, and apparatus for setting a rotational speed of a rotor of a compressed-gas dryer system, without communication from an associated compressor (e.g., without knowing compressor speed or load). Such communication is not always practical or possible (e.g., in the case where a dryer may be provided by a different manufacturer as compared to the compressor). In such a case, the speed or load at which the dryer should run can be determined by making an FAD calculation, so as to determine the volumetric flow rate through the inlet into the drying zone of the dryer. This measurement can be made at the inlet (a venturi or other nozzle), or elsewhere in the system (e.g., other inlets or outlets). Determination of flowrate of compressed-gas to be dried can be done independent of any communication with the compressor. This can be done by measuring inlet temperature, pressure, and pressure drop.

Abstract: Dryer for a compressed gas includes a pressure vessel containing a drying zone and a regeneration zone, a drum provided with regenerable drying agent, an inlet for the supply of the compressed gas to be dried to the drying zone, an outlet for the expulsion of dried compressed gas, a first connection line for branching off a partial stream of the compressed gas to be dried or the dried compressed gas and conducting this partial stream to the regeneration zone, adjustable means for the combination of the partial stream with the supply stream and regulation of the flow from the partial stream with regard to the supplied stream, at least one sensor for measuring at least one measurement value with regard to the function of the dryer, a control unit for processing of the at least one measurement value and installation of a control signal on the adjustable means.

Abstract: A dryer for compressed gas includes 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.
