High temperature TEC modules can be soldered in a higher temperature thanRegular Temperature TECs. Therefore,high temperature TEC modules can fit for higher application requirements. The performance is also as perfect as the regular temperature TEC modules.

Melting temperature for soldering is: 238°C           http://www.analogti.com/thermo-system-components/high-temp-tec-modules.html
Recommended operation temperature: 200°С
