Thermoelectric Cooling & Heating

Welcome to the world of the Peltier Effect: a scientific phenomenon where a temperature gradient is created when an electric current passes through two dissimilar metals. It’s this effect that makes it possible to reliably cool (and heat) devices efficiently, cost-effectively and in small spaces.

Since 1986, Tellurex has been at the forefront of commercial applications for the Peliter effect. We create thermoelectric solutions for devices where conventional, compressor-based refrigeration is impractical or not applicable. Our thermoelectric modules also work as high-efficiency heating elements.

Every Tellurex cooling and heating system is:

  • Extremely scalable.
  • Capable of precisely-controlled temperatures within + 0.1°C.
  • Applicable to virtually any thermal challenge.
  • RoHS Compliant, CFC-free.


  • The target temperature is too precise for thermostatic temperature control.
  • The amount of heat to be moved is smaller than what a compressor-based system is capable of due to size and efficiency.
  • The environment calls for a system not sensitive to position or orientation.
  • The object to be cooled is isolated.
  • Small heat exchange systems are needed.
  • Compact packaging is key.
  • Rate of change in temperature of the target device is important.
  • Cooling and heating is needed from the same device.


  • The target temperature of the heater is less than solder-melting temperatures:
    • Typically 138°C
    • When special solders are used i.e. 260°C
  • The system requires cooling and heating from the same component.
  • A thermoelectric device is already present for cooling purposes.
  • A strict, power budget requiring greater than 100% efficiency for heating.
