The ETX4-7-F1-2323-TA-RT-W6 high temperature, high-performance thermoelectric cooler uses Laird's enhanced thermoelectric module construction preventing performance degrading copper diffusion, which is common in standard grade thermoelectric coolers operating in high temperature environments exceeding 80 °C. It has a maximum Qc of 21.7 Watts when ΔT = 0 and a maximum ΔT of 83.2 °C at Qc = 0.
