Multiple units or assemblies can also be stacked, tiered or otherwise ganged in order to multiply a given volume of conditioned fluid which is produced.
  • Additional variables can include varying the designing of the conductive disk packages, such as not limited varying a thickness, positioning or configuration of a blade or other fluid flow redirecting profile integrated into the conductive plates, as well as utilizing the varying material properties associated with different metals or alloys, such including ferromagnetic, ferrimagnetic, antiferromagnetic, paramagnetic and diamagnetic properties.
