A thermoelectric (TE) module, also called a thermoelectric cooler or Peltier cooler, is a semiconductor-based electronic component that functions as a small heat pump, moving heat from one side of the device to the other. Thermoelectric modules are also sometimes used to generate electricity by using a temperature differential between the two sides of the module.

advantages

• No moving parts
• Small and lightweight
• Maintenance-free
• Acoustically silent and electrically “quiet”
• Heating and cooling with the same module (including temperature cycling)
• Wide operating temperature range
• Highly precise temperature control (to within 0.1°C)
• Operation in any orientation, zero gravity and high G- levels
