Cold Head RDK-408L2 – 8395860

The Sumitomo RDK-408L2 Cold Head (Part No. 8395860) is an essential part of the magnet cryo-system used in several Siemens Magnetom MRI scanners. As a cold head, its primary function is to re-liquefy the helium that has boiled off from the superconducting magnet’s vessel, maintaining the extremely low temperatures required for the magnet’s operation. This process is vital for preventing a quench, which is a rapid loss of superconductivity that can cause significant system downtime. This cold head is compatible with a variety of Siemens systems, including the Magnetom Symphony, Espree, and Avanto series.
