Cold Head RDE-412A4: P/N – 5815457
The Sumitomo RDE-412A4 (P/N 2218465-3) is a fourth-generation cold head assembly designed for GE MRI magnets, featuring a higher heat capacity than its predecessors to efficiently re-liquefy helium and prevent magnet quenching.
As a fourth-generation cold head from Sumitomo, the RDE-412A4 (P/N 2218465-3) is a crucial component in the cryogenic cooling system of GE MRI scanners. This model, also identified by part numbers 5815457 and 5814003, offers a significant upgrade over previous generations like the RDK-408A3 and RDK-408A2, boasting a higher second-stage refrigeration capacity of 1.25W at 4.2K. Its primary function is to re-condense gaseous helium back into a liquid state, a process vital for maintaining the ultra-low temperatures required by superconducting magnets. The RDE-412A4 is known for its reliability and an extended maintenance interval of 10,000 hours, making it a cost-effective solution for ensuring the long-term stability and performance of your MRI system.
