Thermoelectric Peltier Cooler Module Selection

Thermoelectric Cooler’s Specification Include:

TEC series for thermoelectric modules for high heat pumping capacity applications

TEC1 EXTREME Series Thermoelectric Module

Typical applications like:
Food service refrigerator, portable cooler box for cars, liquid cooling and temperature stabilizer. Wine cabinets , Medical equipment, precise temperature control products!

TEC1 series MODULES ARE MADE FROM PREMIUM GRADE CUSTOM INGOTS of Bi2Te3 thermoelectric material not found in the market and perform significantly better in cooling applications than standard modules for high heat pumping capacity applications.  Average cooling capacity is about 40% better with Delta Temperatures averaging 14°F to 18°F  better than standard Chinese modules. The bonding materials are also all design for 190°C maximum hot and cold side operation well above the typical 90°C found in standard modules.

Definitions:I – Input Amps to the TEC (in Amps)
Imax – Input Amps that produce the maximum DT [DTmax] (in Amps)
Qc – Amount of heat that can be absorbed at the cold side face of the TEC (in watts)
Qmax – Maximum amount of heat that can be absorbed at the cold side. This occurrs at I = Imax and when DT = 0. (in Watts).
Th – Temperature of the hot side face of the TEC (in °C)
Tc – Temperature of the cold side face of the TEC (in °C)
DTDifference in temperature between the hot side (Th) and the cold side (Tc). dT = Th-Tc (in °C)
DTmax – Maximum difference in temperature a TEC can achieve between the hot side (Th) and the cold side (Tc). This occurs at I = Imax and when Qc = 0. (in °C)
Vmax – Voltage at I = Imax (in Volts) ****Never operate a module at maximum Vmax !Always at 80% or less of  Vmax.******* Most of the above modules are special order. Please e-mail or Call. We require minimum volumes to produce TEC’s which are not listed below. We are able to produce small sample quantities of TEC’s in our lab. A minimum setup charge will apply plus the cost of the TEC’s!

Our standard modules are:

  • TEC1-12704 EX
  • TEC1-12706 EX
  • TEC1-12708 EX ( 08EX74C )

Our TEC1-12708  EX Peltier module is our most popular module as they demonstrate both minimal power output but offer maximum cooling. Ideal as replacement modules for thermoelectric wine cabinets.

When TEC’s are manufactured they are batch produced and then classified based on performance TEC1-12708 EX TEC’s or our part (Part# 08EX74C)  is the best performing modules in the market. It uses only the top 5% performing material as it’s constructuction feed stock. Therefore, they offer the best performance in relation to power consumption !! OUR EX series Thermoelectric modules are used to replace the heating and cooling TEC in water coolers, wine cabinets, car coolers, portable camping coolers and offer superior performance enhancements compared to the standard TEC modules they are replacing. Especially the cheap Chinese modules you see on amazon and Ebay. Our devices perform 30 to 50% better in cooling and heating applications.
