Silicon Wafer Casting Technology and Waste Heat Recovery
Components for Solar and Thermoelectric Power Generation and Waste Heat Recovery
The RGS proprietary casting process creates silicon based functional materials characterized by their excellent properties like microstructure and homogeneity.
The “RGS” (Ribbon Growth on Substrate) technology is a unique “rapid casting” production process for advanced semi-conductor based alloys.
This RGS process is based on fast direct solidification of wafers out of a melt with well controlled material composition. The process is conducted in a fully enclosed high temperature low pressure atmosphere.
RGS has selected the high temperature waste heat ranging from 700 - 1500 Celcius. The silicon based thermoelectric material produced by RGS has its optimal power output in this temperature range.
In particular a selection was made for heat recovery in the ferrous, non-ferrous and glass industry. These industries are well known for high temperature processes with a high level of waste heat.
Thermagy can be applied as "a smart heat exchanger" to generate electricity out of the waste heat and influence the heat flow from processes or product.
