Abstract: Unit (11) for feeding a reducing solution from the tank to the exhaust duct of an endothermic engine is provided. The unit comprises a supporting head (13) arranged for being associated to an aperture provided in a reducing solution tank and a heating device (15) for heating the reducing solution contained in the tank. The heating device (15) extends from the supporting head (13) and is provided with a duct (17) for a heating fluid. The duct (17) is defined by a side wall (31) which, when the unit (11) is in use, is internally in contact with the heating fluid passing through the duct (17) and externally in contact with the reducing solution present in the tank. At least one portion of the wall (31) of the duct (17) is non-smooth inside and/or outside the duct.

Abstract: A depalletization device (1) that is able to disassemble a pallet (2) that is made up of at least a number of layers (3), includes: a loading/unloading device (6), which is able to separate and extract a layer (3) from the pallet (2); a first conveyor (7) that can be supplied with the layer (3) that is separated from the pallet (2) and is able to move the layer (3) forward; the depalletization device (1) also includes: a second conveyor (10), which can be fed from the first conveyor (7) with an entire layer (3); a pair of third conveyors (11a, 11b) that are able to receive, one or the other alternatingly, the entire layer (3); and actuator elements (14) that can be controlled to transfer the entire layer (3) from the second conveyor (10) to either of the third conveyors (11a, 11b).
