Cryogenic refrigerator
Open
The KDE418SA Cryocooler is a two-stage G-M cycle cryocooler. The cryogenic temperature depending upon the head load imposed is produced by the cryocooler, especially less than 30 K for the first-stage cold station and less than 3.5K for the second-stage cold station with no head load.
