An apparatus (14) and a method for cleaning heat transfer plates (4) suspended between end plates (6, 8) of an open plate heat exchanger (2) are provided. The apparatus is characterized in that it includes a spraying device (16) comprising a first rod (18), at least a first nozzle (20) arranged on a nozzle side (26) of the first rod, which nozzle side is arranged to face a first heat transfer plate side (S1), a second rod (22) and at least a second nozzle (24) arranged on a nozzle side (28) of the second rod, which nozzle side is arranged to face a second heat transfer plate side (S2). The first and second rods are essentially parallel and connected. The spraying device has a first mode in which the first and second rods are arranged to move between the heat transfer plates in a first direction (D1) perpendicular to a longitudinal extension of the first and second rods and parallel to an extension plane of the heat transfer plates. Meanwhile, the first and second nozzles are arranged to spray cleaning fluid onto the first and second heat transfer plate sides, respectively. |
