Abstract (en)
[origin: EP0631103A2] In order to impregnate with water the sponge balls (1) intended for cleaning the tubes of a condenser, they are introduced into a tank (2) whose top part forms a chamber (10) separated from the remainder by a grid (9) through which the balls cannot pass, which chamber is connected to a jack (17) having a piston (19) and then, after the tank and the volumes communicating with it have been filled with water, all the valves giving access to this tank are closed, the piston is withdrawn from the jack, which expels the air from the balls in the chamber, and the whole is refilled with water so as to remove this air and to impregnate the balls with water. <IMAGE>
