ABSTRACT:
A system for cleaning the tubes of a condenser or other heat exchanger unit by circulating sponge balls therethrough by a circulating pump, comprising the improvement in the form of a screen assembly including four vertical screens about 90.degree. apart, two of which confront the discharge end of said condenser to divert the sponge balls downwardly through an internally spiralled stationary tube, while the other two screens confront the discharge pipe of the system. By turning the screens 180.degree., they are completely flushed of debris without the need of removing the balls to an accumulator and stopping circulation of the balls during the screen cleaning operation. Higher efficiency, elimination of down time and lower maintenance costs are provided.
