OUR PRODUCT:  THE ESPRYX™ production process


Innovative, flexible, automated, and mass-scalable process to produce TEG and TEC/Peltier modules


The state-of-the-art manufacturing of TEG and TEC/Peltier modules relies on manual assembly of a multitude of individual TE legs.
Our production process allows the production of TEG and TEC/Peltier modules in a fully automated industrially scalable process. 

The process enables the simultaneous production of all legs of a TEG/TEC within a mechanically robust, thermally and electrically insulating carrier material. The first generation of modules has used the well-established thermoelectric material bismuth telluride (Bi2Te3) with its high Seebeck coefficient and good temperature stability as the active material. The process also permits the use of new innovative materials with superior properties that are under development.

Key features of the resulting modules


Not only the production process has been developed and tested, but the resulting modules (successful pilot series production) are being distributed to test costumers. The special combination of key features makes them the best fit for certain applications. MORE...
