"Cascaded" PE liquid tanks FullWet®/CombiWet®

The Boschung modular system allows tailored and customised mounting systems for liquid tanks, adapted to different carrier vehicles and particular purposes.

Possible drives

  • on lorry platforms (also with ROLL-tec)
  • as a fixed body with intermediate frame
  • with swap systems:
    - on a frame for roll-off hook systems,
    - on a tipper “spider“ frame or with twistlock connectors
  • on semi-trailers or other trailer versions
  • by 3-point linkage on tractors

Taking the available space, payload and centre of gravity into account it is possible to arrange for the best combination for FullWet®, CombiWet®, Airport De-icers, and cleaning vehicles or find special purpose solutions.


  • Modular transport tanks in yellow, made of a shock resistant, maintenance-free and no rust PE material
  • Single tanks freely expandable (“sectioned“system) up to 20,000 l or more, to suit all requirements.
