Technology
diffGEN og RotaChoke are both based on the same technological concept - a patent pending displacement turbine.
The concept is based on volumetric principles and displacement, as known from e.g. lobe pumps.
The lobes is a physical barrier between upstream and downstream fluids - even when rotating, with two synchronized shafts. Forces are applied directly on the lobes, and forces are transformed to rotation almos equivalent traditional pinion transmissions. Consequently, the turbine can also be used to pump, if necessary.
Flow rate and downstream pressure can be controlled dynamically.
