Cryocoolers
| Cryocoolers made by Vacree are G-M cycle cryogenic refrigerators. The tow-stage cryocoolers work down to 10K, the one-stage cryocoolers work down to 30K. |  is a cryogenic characterization system basing on cryocoolers.
Applications:
 Cryopump
Cold trap
Spectroscopy
Materials Characterization
X-Ray Diffraction
Detector Cooling
Cryogenic electronics, for instance: radio astronomy
