Patent ID: 8739823

Claim:
A device for causing turbulent flow in a tank assembly that has an internal fluid cell and a fitting for allowing fluid to enter and exit the fluid cell from the exterior of the tank assembly, the device comprising: a) a main body portion defining a central axis for the device and having a top surface, a bottom surface and radially opposed lateral side walls; b) first and second retaining arms which extend from the each of the radially opposed lateral side walls at the bottom surface of the main body portion of the device, each retaining arm including a radially outer surface located at a distal end thereof which is adapted and configured for supporting the device substantially within the fitting of the tank assembly; and c) a plurality of vane elements, wherein at least one vane element extends from each of the radially opposed lateral side walls of the main body portion of the device, each vane element including a curved surface which is adapted and configured for causing turbulent flow in the fluid cell of the tank assembly by redirecting fluid entering the tank assembly axially through the fitting in a non-axial direction into the fluid cell.
