TEC Microsystems GmbH has more than 750 different types of thermoelectric (Peltier) coolers. With such a nomenclature, divided in to several Series and Sub-Series, it is important to provide useful instruments to search quickly for the most optimal thermoelectric cooler in accordance to customer requirements.

We have two solutions for selecting of optimal TECs - express and complex. The complex solution with various analysis tools is TECCad Software, developed by RMT company. The express search is our Online TEC Select Assistant. It has a search by thermoelectric modules parameters among all available standard TECs nomenclature, provided by TEC Microsystems. Online TEC Select Assistant provides brief search fast and finds the list of suitable thermoelectric modules for customer’s application. The following analysis at different ambient and operating conditions can be done within TECCad software.


TEC Select Assistant window will appear after clicking on the On-Line TEC Select Assistant, which is available here and in several other places on TEC Microsystems web site. Please, enter the required values into appropriate fields and press Search button. The results will be displayed as a table with thermoelectric module type name, it’s performance and electrical parameters and direct link to datasheet.  For complete and detailed analysis of selected thermoelectric module, please, use TECCad Software.
