Ballast tank systems

NEW! Modular ballast diving unit for use with diving bags.

The length of the tank unit can be adjusted to the place relation of the specific U-Boat individually.
Please note: There the volume of the tank unit
changes automatically!
If the tank bag is damaged, the tank still can be emptied!
Thor 14 ESC for the driving of the tank unit pump is recommended.
The new tank units can be installed e.g. into Robbe U47, U31, U2540 or
Schaffer/Hasse U995 to use those U-Boats as static diving submarines.
