  • Publication number: 20260155707
    Abstract: The present invention is directed to a cooling tower comprising a cooling tower structure comprising fill material supported by the cooling tower structure and configured to receive heated process fluid and a motor mounted to the cooling tower structure. The motor comprises a casing and a rotatable shaft and is sealed to prevent fluids, moisture, foreign particles and contaminants from entering the casing. A fan is connected to the rotatable shaft of the motor. Rotation of the rotatable shaft rotates the fan thereby inducing an upward moving mass flow of cool air through the fill material. A basin is attached to the cooling tower structure for collecting cooled fluid. A fluid distribution system distributes the cooled fluid in the basin.

  • Publication number: 20230054112
    Abstract: A direct drive batch mixing system including a vessel having an interior region for receiving a batch, a direct drive electric motor attached to at least one rigid point, a multi-axis load cell located between the motor and the rigid point to provide signals representing forces and moments in multiple axes, and an impeller located within the interior region of the vessel and engaged with the motor such that the motor rotates the impeller. Forces and loads on the impeller are directly supported by the motor and measured by the multi-axis load cell. In some embodiments, a programmable controller generates control signals that control the motor's speed (RPM), torque and direction of rotation, and receives feedback signals for adjusting the motor's speed and/or torque and/or direction of rotation.
