[Description]

The Sumitomo Heavy Industries RDK-408Q is a two-stage Gifford-McMahon cryogenic cold head designed for closed-cycle refrigeration in scientific instrumentation, superconducting magnet systems, and other low-temperature applications. Part of the Sumitomo SRDK-408 cryocooler series, the cold head operates using compressed helium gas supplied by an external compressor. Its internal displacer and regenerator assembly produces refrigeration through controlled helium expansion, allowing the system to maintain cryogenic temperatures without continuous consumption of liquid cryogens. The RDK-408Q features separate first- and second-stage cooling sections and is designed for integration into specialized cryogenic refrigeration systems requiring continuous, mechanically driven low-temperature cooling.
