HZ-20 Thermoelectric Module (used, but for only 1 hour)
THE HZ-20 THERMOELECTRIC MODULE
The HZ-20 module consists of 71 thermocouples arranged electrically in series and thermally in parallel. The thermocouples consists of Bridgeman Cast, Bismuth Telluride based, semiconductors to give the highest efficiency at most waste heat temperatures as well as high strength capable of enduring rugged applications. The bonded metal conductors enable the HZ-20 module to operate continuously at temperatures as high as 250°C (480 F) and intermittently as high as 400°C (750 F) without degrading the module.
