UltraTEC™ UT Series

High heat flux density module

The UltraTEC UT Series is a high heat flux density thermoelectric cooler. The thermoelectric module is assembled with a large number of semiconducting thermoelectric (TE) couples to achieve a higher heat pumping capacity than standard single stage thermoelectric modules. This product line is available in multiple configurations and is ideal for applications that require higher cooling capacities with limited surface area. Assembled with Bismuth Telluride semiconductor material and thermally conductive Aluminum Oxide ceramics, the UltraTEC UT Series is designed for higher current and larger heat-pumping applications. For all UltraTEC UT Series thermoelectric coolers, wire is stranded, 152 mm (6.0 in.) long or 200 mm (8.0 in.) and PVC insulated.
