多级致冷器系列产品是为大温差应用面设计的。这类致冷器适用于需要中小制冷功率，大温差的场合。典型应用于IR-检测，CCD和光电等领域。不同层叠方式的设计可满足深度制冷的需求。这类致冷器能获得比标准单级致冷器更大的温差。
The Multi-Stage TEM series is designed to provide significantly higher AT. These TEMs are suitable for
areas include IR-detectors, CCD arrays and electro-optics. These items are also available with
low temperature applications where a small or medium cooling capacity is required. Typical application
different configurations in cascade designs to meet a range of deep cooling applications. They
providehigher temperature differentials than obtainable with standard single stage TEMs.
