Our vacuum furnaces designed for directional solidification (based on Vertical-Gradient-Freeze Process) of multi-crystalline solar silicon ingots for photovoltaic wafer production.
MultiCrystallizer VGF732 Si produces ingots with a maximum dimension of 834mm x 834mm x 250mm and a weight of approx. 400-450 kg.
The new HC ("High Crucible")- version has an increased capacity of silicon load; the dimension of the ingots produced is up to 834mm x 834mm x 340mm with a weight of approx. 420-560 kg.
