Stator considerations for CellVessel

Tube stator with baffles for axial mixing

CellVessel and variants may be ordered with tube shaped stator and integrated external baffles converting the otherwise radial mixing to much more efficient axial vortex mixing. Donut shape flow pattern for improved mass transfer, increased productivity, lower RPM, gentle to cells and micro-carriers. See also Application Note for stator performance.

Principles of the tube stator for CellVessel, LowRider special SUBs is the opposite of the Viktor Kaplan “turbine” for power generation in hydro power plants.

During rotation of the fixed blade angle impeller the passing media receives energy and changes slightly pressure as it passes the impeller. The media receives energy / converts kinetic energy to velocity.

Depending on impeller rotation direction and media flow direction the in/outlet is a radial blade shaped stator design that wraps around the impeller's stator tube. Media is directed / exhausted tangentially through the radial gate and spirals upwards / downwards along the inner surface of the vessel.
