Single Stage Thermoelectric Modules

Single stage thermoelectric modules provide for a maximum temperature difference of up to 74 оС between the hot and cold sides.

The required thermoelectric module types are selected from the General Specification or from the Table given below, based on the marking ТМ-ААА-ВВ-СС М, where:

  • TM — thermoelectric module
  • AAA — number of thermocouples
  • BB — dice cross section, mm
  • CC — current at maximum temperature difference ΔTmax, А
  • М — modules manufactured using the patented glue layer technology

Variants of modules design:

Imax — current consumption at maximum temperature difference (ΔTmax), A
Umax — voltage supplied at maximum temperature difference (ΔTmax), V
Qcmax — maximum cooling capacity at Imax and ΔT = 0 °C, W
ΔTmax — maximum temperature difference at Imaх and Qc = 0, °C

*At the module hot side temperature Тhot=50 °С ΔTmax rises to 82-83 °C

Detailed characteristics of a Peltier cooler can be obtained by clicking the download corresponding to the module.

If you did not find thermoelectric module that meets your requirements, we are ready to design the one at your request.

At the customer’s request, Pelrier modules with additional options may be manufactured:
