Description:
Million cycles Single stage Peltier Thermoelectric module forsuperior cooling.The 127 couples, 40 mm * 40 mm sizesingle stage module ismade of selected high performance ingot and fabricated by ourunique “soft” processes to achieve superior cooling/heatingperformance. The module is able to run million thermal cycles in 70°C temperature change range with less 3% degrading. It is good forthe need of frequently cooling down and heating up to 100 ºCapplications. If higher operation or processing temperature isrequired, please specify, we can design and manufacture the custommade module according to your specialrequirements.

A typical 127 couples module is fabricated by the unique “soft”process and has demonstrated that it only has 2.5% degrading after300, 000 thermal cycling. The below graphic shows that in beginning120, 000 cycles, it degrade about 2.5%, and then go on stable withvery tiny degrading in further 180, 000 thermal cycles. It isderived out that the modules can go over million thermalcycles.
