2-stage TECs are very useful when single-stage TECs are not able to provide the required temperature difference. Miniature size and up to 90K temperature difference determine the area of application as for deep freezing of small size electronic devices (mostly sensors and CCD matrixes for self-noise reduction). Also multistage TEСs are widely used for deepfreeze refrigerators for medicine and scientific equipment.
