ETX15-28-F2-5252-TA-RT-W6
MFG Part Number 387004921
HiTemp ETX Series Thermoelectric Cooler
The ETX15-28-F2-5252-TA-RT-W6 high temperature, high-performance thermoelectric cooler uses Laird Thermal Systems' enhanced thermoelectric module construction preventing performance degrading diffusion, which is common in standard grade thermoelectric coolers operating in high temperature environments exceeding 80 °C. It has a maximum Qc of 321.9 Watts when ΔT = 0 and a maximum ΔT of 83.2 °C at Qc = 0.

You can interact with the Performance Curves below to estimate the cooling performance by entering the thermal and electrical operating conditions for your application.
