Cleaning system

A cleaning system for use with a plurality of tubes of a heat exchange system, the heat exchange system having an intake and an exhaust, the cleaning system comprising:

• a displacement system having a first port and a second port, the displacement system being operable for drawing liquid into the second port and expelling the drawn liquid out of the first port when in a first operating mode and drawing liquid into the first port and expelling the drawn liquid out of the second port when in a second operating mode;
• a manifold defining a first chamber and a second chamber, the manifold comprising a separator disposed between the first chamber and the second chamber, the first chamber for receiving at least one cleaning ball, the separator defining at least one aperture for fluid communicating the first chamber with the second chamber and being shaped and dimensioned for substantially impeding passage of the at least one cleaning ball therethrough;
• and
• a flow diverting system adapted for fluid communicating the first port of the displacement system and the intake to the first chamber of the manifold and substantially impeding fluid communication of the first port and the exhaust with the second chamber and first chamber respectively when in the first operating mode, the flow diverting system being further adapted for fluid communicating the first port and the exhaust to the second chamber and first chamber respectively and substantially impeding fluid communication of each of the first port of the displacement system and the intake with the first chamber of the manifold when in the second operating mode, the at least one cleaning ball being displaced from the first chamber to the intake of the cleaning system for passage through the plurality of tubes when in the first operating mode and the at least one cleaning ball being drawn from the exhaust of the cleaning system into the first chamber when in the second operating mode, wherein the at least one cleaning ball passages through the plurality of tubes for cleaning thereof.
