Peltier – Thermoelectric Cooler Modules

TE Technology’s Thermoelectric, or Peltier Cooling Modules (also known as a TEC or a TEM) come in a wide variety of types and sizes. While typically used for cooling, they can also be used for heating (by reversing the electric current flow) and even power generation.


POTTED modules have a PERIMETER SEAL around the elements and are recommended when cooling below the dew point temperature. Potting can be added as an option via the pull-down box on each individual module page.Our online Peltier Thermoelectric Cooler Module Calculator can provide assistance with selecting a module for the greatest coefficient of performance or for minimizing the size (and usually the cost) of the module. Be sure to review the Instructions for Using Online Thermoelectric Module Calculator for complete details on how to use the program. Please note that thermoelectric modules must be used with a heat sink. These heat sinks almost always need to be fan or liquid cooled to have a sufficiently low thermal resistance. Improper heat sinking can cause damage to the module. Be sure to review our FAQ’s regarding reliability and our recommendations for using pulse-width modulated temperature controllers.
