Thermoelectric TEG Power Modules Under 200°C

TEG2 series modules are CUSTOM designed for liquid to liquid thermoelectric power generation and energy harvesting applications. TEG2 modules are designed for temperatures on the hot side below 200°C. TEG2 custom series modules are designed for maximum heat flow (TEG2-07025HT-SS) when using liquid to liquid designs because liquid can carry and take away extreme amounts of thermal energy compared to teg air designed systems.

Just the opposite is true for our TEG2-126LDT module (Bottom of page) it is designed for the opposite effect. Harvesting body heat requires slow moving heat to maintain an expanded DT. A thick element TEG module accomplishes just that with no seal so, there is no thermal bridge path. The DT is maintained guaranteeing effect power production with minimal temperature difference.

For higher temperature go to TEG1 Series modules they are designed for up to 320°C

Our highest TEG CMO modules work up to an amazing 800°C with no or little degradation over 40 years!

TEG2-126LDT for Body & Sensor Power Thermoelectric Harvesting Applications!

TEG2-126LDT
The TEG2-126LDT is a Low Delta Temperature designed module. Ideally designed for body and micro harvesting applications. Micro Scavenging heat to power “internet of things” is difficult at best. All of these scavenging devices require autonomous power to be effective and long lasting without scheduled service appointments to replace batteries.

Most require maybe 1V at 20ma or more, some less? The main consideration is How to design a TEG module to provide the most possible power given so little the available DT provided in the application.

The TEG2-126LDT thermoelectric power module is a cost effective design that provides effective energy harvesting from minimal heat differentials. (Even high heat with low DT’s has the exact same principles).
