General Electric MRI Plant, South Carolina

The General Electric MRI plant in Florence, South Carolina, is the primary production center for Magnetic Resonance Imaging machines, scanning devices that have revolutionized medial diagnosis, and other industries. MRI image sensors use around a quarter of all the helium that is produced in the world, making this a major destination for the specialty trucks carrying the cryogenically cooled (to -452 degrees) and compressed (at 2,800 lbs per square inch) liquefied gas.
