High-Power Thermoelectric Module

September 30, 2014 by Jeff Shepard

GMZ Energy, Inc. today announced the TG16-1.0, a new thermoelectric generation (TEG) module capable of producing twice the power of the company's first product, the TG8. By doubling the power density, GMZ's new module substantially increases performance while maintaining a minimal footprint. The TG16 can produce 15 Watts of power when a temperature gradient of 500 degrees C is applied (assumes 100 degrees C cold-side temperature). The small size, high power output and reliability of this device make it suited for local, high reliability power generation from waste and primary heat sources.

The added power density of the TG16 makes it particularly useful for applications with very high temperature heat flows. The device has been implemented successfully in applications with heat flows in excess of 1000 degrees C. The TG16’s lower thermal resistance maintains the hot-side temperature of the module below 600 degrees C even with a high-temperature exhaust stream present.

Cheryl A. Diuguid, CEO of GMZ Energy, said: “With this new, high-power module, GMZ continues to push the boundaries of thermoelectric technology through the development of industry-leading products. We look forward to using this breakthrough product to help our customers reach a new level of efficiency and reduce costs.”

The highly-efficient TG16-1.0 directly converts waste heat into usable electricity and is well suited for extremely high temperature environments, such as those in boilers and furnaces. The module’s high thermal power capability enables safe operation and long-term reliability in temperature streams above 1000 degrees Celsius. Customers will the find the TG16-1.0 trgeted for combined heat and power applications where the module is directly exposed to combustion flows.

Now, with two product offerings, GMZ is capable of providing a solution to even more OEM partners around the world. This new module will augment the TG8 module, broadening the product line and enabling dramatic efficiency improvements and new functionalities in products requiring high power density. The TG16-1.0 is currently available for sampling to qualified OEM manufacturers.
