4 Kelvin Closed Cycle Refrigerator Systems from Janis and SHI
Sumitomo (SHI) 4 K Refrigerator - RDK-101J (0.2 Watt @ 4.2 K)
Overview
These systems provide 0.2 Watts of cooling at a temperature of 4.2 K at the second stage and can reach a minimum temperature of about 3.0 K (with no parasitic or experimental heat loads). The 0.2-Watt systems employ a smaller compressor and cold head than the 1-Watt systems. Compact water- or air-cooled compressors and 3-meter long flexible gas lines complete the refrigerator package.
