Thermoelectric Cooling Technology

Cooling with the Peltier Effect

A thermoelectric cooler (TEC) transfers heat using the Peltier effect. When DC current passes through the semiconductor elements, heat is absorbed on the cold side and released on the hot side.

By reversing the current direction, the cooling and heating sides can be switched, providing precise, compact, and reliable temperature control without refrigerants or compressors.

DC Power → Peltier Effect → Heat Transfer → Cooling / Heating.
