74C Delta T higher performance Peltier thermoelectric cooler TEHC1-12708-74

74C Highest Delta T Single stage Peltier Thermoelectric module for superior cooling.

     The 127 couples, 40 mm * 40/44 mm size single stage module is made of selected high performance ingot to achieve superior cooling performance and greater delta T up to 74 ºC, designed for superior cooling and heating up to 100 ºC requirement. It has higher cooling efficiency than normal type module. If higher operation or processing temperature is required, please specify, we can design and manufacture the custom made module according to your special requirements.

  Standard Performance Graph Qc= f(ΔT)

 

    

 Standard Performance Graph V= f(ΔT)

 

  

 Standard Performance Graph Qc= f(V)

 

  

 Standard Performance Graph COP = f(V) of ΔT ranged from 0 to 30 ºC 

 

   

Standard Performance Graph COP = f(V) of  ΔT ranged from 40 to 60/70 ºC

 Remark: The coefficient of performance (COP) is the cooling power Qc/Input power (V × I).

 

Operation Cautions

Cold side of the module sticked on the object being cooled

Operation below Imax or Vmax

Hot side of the module mounted on a heat radiator

Operation or storage module below 100 ºC

Work under DC
