Special features

cleaning ball basic type S300 with corundum coating

To ensure effective cleaning, the ball charge is exchanged once the coating has worn off from most of the cleaning balls.

This ball type should not be used as regular operating ball.

Application also after the corundum ring ball was used to remove scaling from the entire tube surface.


The microscopically visible scoring resulting from the ball use is smaller than the scoring resulting from the manufacture of the stainless steel and titanium tubes itself.
Uncontrolled use of this cleaning ball type may damage tubes and system parts.
