PHANTOM 2500

In very many biogas plants only fast running submersible mixers have been installed. A large part of the energy input is thereby expunged, to some extent unnecessarily, by the creation of local turbulences, especially in fermenters and postdigesters. In extreme cases several fast runners then operate only in the restricted caverns that surround them. The Phantom 2500 is a sensible alternative here.

Thanks to its 2500 mm diameter propeller this large mixer can produce extraordinarily large thrust despite low energy consumption, thereby creating a global underflow in the fermentation tank which is gentle on bacteria. Our Repowering-Pipe System can be easily retrofitted in the filled tank. Although the Phantom 2500 generates far larger thrust forces than a fast runner, it only requires a fraction of the energy, enabling both the mixing to be improved and the energy costs to be reduced by up to 70% as part of a retrofitting measure.
