Cold Head Assembly RDK-408A3: P/N – 5445412

The Sumitomo RDK-408A3 cold head is a standard-bearer in the medical imaging industry, widely recognized for its robust design and exceptional reliability. As a primary component of a closed-loop cryogenic system, its function is to re-liquefy helium gas, preventing costly boil-off and maintaining the superconducting state of the MRI magnet. This model is often cross-referenced with P/N 5445412 and is used across a broad spectrum of MRI systems, including those from GE, Siemens, and Philips. Known for its quiet operation and long service intervals, the RDK-408A3 is an ideal replacement part for facilities looking to ensure the long-term, stable operation of their MRI equipment. We offer this cold head in new, used, and expertly refurbished conditions, all thoroughly tested to meet or exceed OEM specifications.
