A radial compressor unit for compressing gas has several compressor stages. Each compressor stage includes an impeller having rotor blades, and a flow channel arranged downstream of the impeller, as viewed in the flow direction of the gas to be compressed, having a diffusor section, a deflection section, and a recirculation section having guide blades. The gas compressed in a compressor stage can be removed as cooling gas for cooling a component to be cooled, and can be conveyed in the direction of the component to be cooled. The cooling gas can be removed adjacent to an intermediate wall of the compressor stage from the deflection section and/or the recirculation section of the flow channel of the compressor stage.

1. A radial compressor unit for the compression of gas, comprising: a plurality of compressor stages (11, 12, 13), each compressor stage (11, 12, 13) having: an intermediate wall (32),an impeller (18) with rotor blades (23),a flow channel (24) arranged, with respect to a flow direction of the gas to be compressed, downstream of the impeller (18), the flow channel (24) having: a diffuser section (25) directly following, in the flow direction, the impeller (18),a deflection section (26) following, in the flow direction, the diffuser section (25), anda recirculation section (27) with multiple guide blades (28), the recirculation section (27) following, in the flow direction, the deflection section (26), wherein the diffuser section (25), the deflection section (26) and the recirculation section (27) are bounded on the inside by the intermediate wall (32), anda removal pipe (35) having a projecting section (37) projecting into the flow channel (24) and having, at an end of the projecting section (37) within a flow path of the flow channel (24), a removal opening (36) arranged in a region of the flow channel (24) proximate the deflection section (26) and adjacent to the intermediate wall (32), the removal pipe (35) and removal opening (36) being configured and arranged such that compressed gas, as cooling gas, is removed, by the removal pipe (35), from the flow channel (24), in a region of the flow channel (24) adjacent to the intermediate wall (32) so as to remove cooling gas from the region of the flow channel (24) at which the removal opening (36) is located.
