Abstract (en)
[origin: WO2014056677A1] The present invention relates to a wall ring for receiving in particular an axial fan (6), comprising an annular body (1) with a flow inlet opening (2) and a flow outlet opening (3) and a central longitudinal axis X-X as well as an annular wall (4) extending between both openings (2, 3). The annular wall (4) has a cavity (13) which is enclosed by an outer wall (11) and an inner wall (12), in which an electrical heating element (24) may be secured at least over a partial area of the periphery of the annular wall (4). The annular body (1) consists of at least two partial bodies (14, 15) which are formed by a division of the annular body (1) in a separating plane that extends perpendicular to its longitudinal axis (X-X) and are detachably connected to one another.
