Abstract
A cleaning system for use with a heat exchanger and a fluid pressurizing assembly includes a wand assembly, a pivot assembly, and a movement mechanism having a body and a piston rod moveable relative the body in response to fluid pressurization. The wand assembly includes a wand in fluid communication with the fluid pressurizing assembly, and having a first orifice configured to eject fluid toward the heat exchanger. The wand is supported by the pivot assembly such that the wand is selectively pivotable about a first pivot axis. The movement mechanism connects to the pivot assembly at a second pivot axis offset from the first pivot axis such that selective movement of the piston rod produces pivotal movement of the wand about the pivot axis.
