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.
The comparison illustrates the difference:
With Geberit SuperTube (illustration on left), the discharge capacity is 12 l/s. 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.
A conventional discharge pipe (illustration on right) achieves a discharge capacity of 12.4 l/s with pipe dimensions of d160 and an additional d90 ventilation pipe.
The outflowing water is set in rotation in the Geberit HDPE Sovent fitting.
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.
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.
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.
