10 K Cryocoolers — CTI-Cryogenics M-22 10 K Refrigerator (1 W at 20 K)
The Model 22 CTI-Cryodyne refrigerator system is a closed-cycle helium refrigeration system based on the Gifford-McMahon thermodynamic cycle. It is available in both single and 2-stage configurations to suit a variety of applications that require a compact cryocooler. The CTI system consists of a refrigerator assembly, compressor assembly, and a customized installation kit consisting of flexible interconnecting gas lines and refrigerator cable ranging from the standard 10 ft separation length up to 300 ft lengths. please see the compressor page for more information.
The single-stage M-22 is designed to provide up to 11 W of heat lift at 77 K for cooling of high-temperature superconductors, detectors, and optical devices.
The two-stage M-22 is designed to provide useable heat lift under 10 K and up to 1 W at 20 K and 8 W at 77 K simultaneously. Applications include spectroscopy, low-temperature thermometry, amplifier cooling, and LASER frequency tuning. Download the CTI-Cryogenics Cryodyne Refrigeration System Datasheet.
