GEBERIT SUPERTUBE
THE SPACE-GAINING SYSTEM
Hydraulically optimised drainage of high-rise buildings
Geberit SuperTube technology is based on the perfect interplay between system components, which enables waste water systems to be installed in a particularly space-saving manner in high-rise buildings.
SuperTube means a parallel ventilation pipe is no longer required, creating more space for the residential and floor space. Pipelines with consistently smaller dimensions allow smaller pipe ducts to be used. Horizontal pipelines can be laid to a length of up to six metres without a slope to save even more space.
- More residential and floor space
- Simple planning and quick installation
- Smaller, consistent pipe diameters of d110
- Maximum discharge capacity of 12 l/s
- No additional ventilation pipes required
- Horizontal pipelines without slopes (up to 6 m)
Space-saving installation explained
Conventional Drainage Systems
A large amount of space is required for conventional drainage systems.
A conventional discharge pipe achieves a discharge capacity of 12.4 l/s with pipe dimensions of d160 and an additional d90 ventilation pipe.
With Geberit SuperTube
Space is saved without a ventilation pipe and a slope.
The discharge capacity is 12 l/s as this technology facilitates a consistent discharge pipe with a pipe dimension of d110, meaning there is no need for a ventilation pipe. What's more, the horizontal pipelines can be laid to a length of up to six metres without a slope.
Perfect interplay of Supertube components
The outflowing water is set in rotation in the Geberit HDPE Sovent fitting.
The Geberit HDPE BottomTurn
The annular flow becomes a layered flow
The column of air is maintained in the event of a change in direction.
The Geberit HDPE BackFlip bend
The layered flow becomes an annular flow once again
To ensure the column of air in the vertical direction is not disrupted.
Geberit HDPE Sovent fitting d110
The optimised product geometry of the Geberit HDPE Sovent fitting guides the water into the stack and sets it in rotation, which causes it to press against the pipe wall. The resulting annular flow creates a stable, continuous column of air on the inside, which facilitates a discharge capacity of 12 l/s.
Geberit HDPE BottomTurn bend
With the Geberit HDPE BottomTurn bend, a change in direction causes the wall of water to break and the annular flow to become a layered flow without disrupting the column of air. This change significantly reduces impulse losses compared with conventional solutions.
Geberit HDPE BackFlip bend
The twisted Geberit HDPE BackFlip bend causes the layered flow of water to swirl, which allows it to rotate through the vertical pipeline as it drains away in an annular flow. The inner air column in the subsequent stack is maintained.
Geberit SuperTube planning tool
Straightforward planning thanks to the dimensioning tool. The web tool guides you through the process of planning a one-dimensional discharge pipe step by step. The values and information obtained can then be collated and downloaded as a PDF file.
