Frequently Asked Questions About
Buying Thermoelectric Modules

Are all thermoelectric modules on the market essentially the same?

No. Each company takes its own approach with manufacturing processes and material formulations, some to assure the highest quality and others to deliver the lowest price.

What sorts of differences are seen?

There are two major areas of difference and each impacts performance:

• Workmanship: In good quality devices, manufacturers strive for superior alignment of semiconductor pellets, strong bonds between pellets and conductor tabs, strong bonds between tabs and substrates, and superior cleanliness. In poor quality devices, electrical and thermal shorting can be created by bad alignment and debris; furthermore, inadequate bonds can compromise strength.
• Material Technology: Each manufacturer jealously guards its formulation of semiconductor material. Some companies, like Tellurex, have become international standards for the benchmarking of their materials. In fact, Tellurex has exclusive worldwide licensing to the highest performing power generation materials. Other companies are not as successful in the development of semiconductor material, and the differences in performance can be highly significant.

There are thermoelectric modules available from third party sources at highly discounted prices. Are these different from other thermoelectric modules?

Yes. Low budget thermoelectric modules, in addition to the problems noted above, may be scrap or defective products that a reputable company would never release to a customer

I purchased a thermoelectric module with the same specifications as the Tellurex product but it does not perform as well. Why is that?

We have seen specifications from another company that make it appear that a device has an incredible capacity for heat-pumping as expressed in watts. Upon examination, we have found that their published data actually describes the heat that their module dissipates in its own resistance while running at V_Max. We recommend that you discuss all published specifications with their sales support staff. If that experience disappoints you, call us.

Is Tellurex still the global leader in new thermoelectric materials, engineering and technology?

Yes.

Do you have a minimum order requirement?

In a word, No. We welcome all customers. We make it easy to purchase low volume orders through our secure Shopping Cart. In addition, we offer substantial discounts to customers for high volume orders. We work to publish as much information as possible on our website to enable informed decisions regarding the effective use of thermoelectric technology in a broad range of applications.

Thermoelectric module performance and quality vary significantly among module providers. Our testing shows that our products have a consistently measurable performance advantage. We invite you to confirm this for yourself. Please let us know what you find. And thank you for shopping with Tellurex Corporation

How long has Tellurex been in business?
