The TT-Units are available in different sizes

Ranging from a suction diameter of 200 mm to 350 mm with a maximum power consumption of 95 to 375 kW respective.
The pressure at the design point ranges from 4.2 to 5.2 bar, which makes it possible to use the unit with a discharge length of over 2500m.
Dredging depth is limited only by practical aspects.
When suspended from a crane, the dredging depth can be up to hundreds of meters.
