Applications of Peltier Modules in Cooling and Heating

Peltier modules (thermoelectric coolers or TECs) are unique in that they can both cool and heat, depending on the direction of the electric current. This dual-mode functionality makes them highly valuable in a wide range of applications — especially where precise, compact, and fluid-free thermal management is required.
