Sumitomo (SHI) 6 K Refrigerator

RDK-408S

6 K Cryocooler

With a minimum temperature below 6 K, the RDK-408S is primarily noted for its high cooling power and modest cost.  A conventional lead regenerator offers a unique combination of power, reliability, and affordability.  (Please see our Compressors page for more information.)

Characteristics: Applications:
Larger Capacity of 6.5 W @ 10 K Cryopumps
Orientation Independent Cryogenic Shield Cooling
Push-button Operation Laboratory Cryostats
