eTEG PG8000 launched by Nextreme

The eTEG PG8000 Series contains five new modules which can be configured electrically in series to produce higher output voltage. These modules can produce between 2.7mW to 21.6 mW of output power and open circuit voltages of 0.17V to 1.35V at a temperature differential (ΔT) of only 10K. At 50K ΔT, the series can produce 65mW to 520mW of power and open circuit voltages of 0.85V to 6.8V. The components can be configured electrically in series to create higher output voltage.

The devices can offer electricity to a load directly when a constant heat source is accessible or can be used in combination with batteries when the heat source is variable. The advanced technology eliminates the need to use wires or replaceable batteries as a power source for remote applications. Thermoelectric power generators convert waste heat from thermal sources into electricity as an alternate source of energy.

Heat fluxes in this series simplify integration with heat sinks that are necessary to maintain constant heat flow, functioning with moderate heat flux density that equal the heat flux found in common sources of thermal energy such as industrial manufacturing processes and piping.

The new series includes a seal ring which works as a barrier to moisture and other contaminants that could affect the performance of the module. The high mechanical strength seal ring which is made from a Cirlex polyimide film, delivers mechanical isolation across the thermoelectric device, eliminating vertical force and sheer issues.

The new PG Series gives our customers a simple, robust pathway to greater output power for energy harvesting applications,” quoted Dave Koester, vice president of engineering for Nextreme. “The modules are designed to match the performance of readily available heat sinks for simplified and improved thermal to electrical power conversion.”

Shipments of the eTEG PG8000 Series will start in the first quarter of 2013. Pricing is available upon request.
