We produce a wide range of thermoelectric modules with different dimensions and configuration which can be used for various applications. Micro-modules are intended for cooling of radiation detectors and other components of electronic devices. Large modules with significant cooling capacity are used in industrial machinery, testing equipment and systems of environmental conditioning. Our technical capability of growing semiconductor materials allows optimization of electrical, thermo-electrical and mechanical properties of a material for particular application and manufacturing the module according customer specifications. Our modules are manufactured using the proprietary process that assures reliable operation at ambient temperature up to 250 °C.
