ABSTRACT:
To impregnate with water the spongy balls (1) that are to be used for cleaning the tubes of a condenser, the balls are put into a tank (2) whose upper portion forms a chamber (10) that is separated from the remainder of the tank by a grid (9) to which the balls cannot pass, the chamber is connected to a pump (17) having a piston (19), and then after the tank and the volumes in communication therewith have been filled with water, all of the valves giving access to the tank are closed, the piston of the pump is pulled back, thereby causing air to be expelled from the balls in the chamber, and the volume is again completely refilled with water so as to evacuate said air and impregnate the balls with water.
