CP Series CP14-199-045
Thermoelectric Modules
Page 1 of 2
The Ceramic Plate (CP) Series of Thermoelectric Modules (TEMs) is
considered ‘the standard’ in the thermoelectric industry.
This broad product line of high-performance and highly reliable TEMs
is available in numerous heat pumping capacities, geometric shapes,
and input power ranges. Assembled with Bismuth Telluride
semiconductor material and thermally conductive Aluminum Oxide
ceramics, the CP Series is designed for higher current and large heat-
pumping applications.
