Abstract: The system and method of the invention pertains to use of a back iron on one or both ends of the impeller to increase the magnetic field density, and thus strengthen the magnetic coupling. In addition, pie-shaped (i.e. wedge) magnets, or variations thereof, increase the utilization volume and hence provide higher torque to allow the use of less expensive material (e.g. ferrites). In another embodiment, the rotor side is constructed with a Halbach array which increases the torque without the need to add a back iron piece. In another embodiment, an axial flux stator is implemented to replace the drive-end magnets and the drive motor.

Abstract: Disclosed herein is a system and method for condensing moisture in a gas stream entering or leaving a bioreactor, the system comprising: a contact condenser container fluidically coupled to the bioreactor through an exhaust line; a condensate accumulator fluidically coupled to the contact condenser container through at least a first condensate line and a second condensate line; the condensate accumulator further fluidically coupled to the bioreactor through a condensate overflow line; a first condensate control device disposed on the first condensate line and configured to control a flow of condensate leaving the contact condenser container and entering the condensate accumulator; and a second condensate control device disposed on the second condensate line and configured to control a flow of condensate leaving the condensate accumulator to be mixed with the gas stream.
