Abstract: A refrigerant dryer, in particular a compressed air refrigerant dryer, is provided for drying a gaseous fluid while cooling the gaseous fluid using a refrigerant. The dryer includes a pressure fluid-refrigerant agent-heat exchanger (30) in which a cooling of the gaseous fluid takes place directly or indirectly by a refrigerant conveyed in a primary loop (16), one or more refrigerant compressor/compressors (24) for operating the primary loop, and a cold accumulator (13) with an accumulator-side heat exchanger (20) which couples an accumulator discharge fluid to a cold accumulator medium (14). The pressure fluid-refrigerant agent-heat exchanger (30) and the cold accumulator (13) are fluidically connected or can be brought into fluidic connection via a discharge loop (15) for an accumulator discharge fluid.

Abstract: A method is provided for applying a cover layer (9) to a net structure (4) to be used for medical purposes, in particular a thrombosis filter. The net structure (4) is applied to a planar substrate (1) that covers openings (5) of the net structure on one side, wherein the openings (5) across the uncovered side are filled with a sacrificial material (7), in particular copper. The net structure (4) is lifted from the substrate (1). A cover layer (9) is deposited on the surface previously covered by the substrate, and the sacrificial material (7) is removed.
