CP (Ceramic Plate) Thermoelectric Modules Laird CP (Ceramic Plate) Thermoelectric Modules feature high-performance, highly reliable TEMs in numerous heat pumping capacities, geometric shapes, geometric sizes, and input power ranges. These components are constructed using Bismuth Telluride semiconductor material and thermally conductive aluminum oxide ceramics. The CP Thermoelectric Modules offer precise temperature control and reliable solid-state operation. These TEMs are designed for higher current and large heat-pumping applications, making them ideal for medical lasers, lab science instrumentation, clinical diagnostic systems, photonics laser systems, electronic enclosure cooling, food/beverage cooling, and chillers (liquid cooling).
