Sponge rubber ball for special hydraulic conditions
for copper and brass tubes in low-salinity waters.
for copper and brass tubes (particularly combined with ferrous sulphate dosing) in low-salinity waters.
low-salinity water : 12 balls/hour and tube
mixed water: examination required
Special cleaning ball for copper-alloy structured tubes, or for particularly unfavourable hydraulic conditions.
Due to the roughness of copper-alloy tube surfaces, the cleaning ball type S170 may also be applied as long-life ball (L170).
