The power module is designed and manufactured by our unique technology for converting heat source directly into electricity. The module is a lead tin telluride based thermoelectric module that can work at the temperature of as high as 500 °C (932 oF) heat source continuously, and up to 600°C (1112 oF) intermittently. The thermoelectric module will generate DC electricity as long as there is a temperature difference across the module. The more power will be generated when the temperature difference across the module becomes larger, and the efficiency of converting heat energy into electricity will increase. It can achieve much higher efficiency than Bismuth Telluride module if heat source temperature can go up to 500 °C (932 oF) due to its larger temperature difference. The module is enclosed in a metal casing for preventing oxidation in high temperature and poor environment. 

If you did not find thermoelectric module that meets your requirements, we are ready to design the one at your request.
