A shell-and-tube equipment has a cylindrical geometry and is arranged along a vertical axis. The shell-and-tube equipment comprises an upper chamber and a lower chamber connected to a common tube bundle on opposite sides. The upper chamber is provided with at least an inlet nozzle for inletting a first fluid. The tube bundle is surrounded by a shell provided with nozzles for inletting and outletting a second fluid which exchanges heat with the first fluid through the tube bundle. The upper chamber encloses at least a distribution device configured for uniformly delivering the first fluid towards the tube bundle. The distribution device comprises an annular channel which is arranged around the vertical axis and is in fluid communication with the inlet nozzle. The distribution device comprises a plurality of channel modules of circular trapezoid shape, tightly joined together at their respective vertical edges for forming the annular channel.
