The Multi-Stage TEM series is designed to provide significantly higher ΔT. These TEMs are suitable for low temperature applications where a small or medium cooling capacity is required. Typical application areas include IR-detectors, CCD arrays and electro-optics. These items are also available with different configurations in cascade designs to meet a range of deep cooling applications. They provide higher temperature differentials than obtainable with standard single stage TEMs.

Type 2 (T2) TEMs feature a "porch" for more accurate heat distribution.
This makes the L2 dimensions slightly longer than the L1 dimension.
| Imax: | Maximum input current in amperes at Qc=0 and ΔTmax |
