PV80 : DSS furnace G2

Directional solidification system furnace of silicon ingot crystal growth for photovoltaic applications.

The PV80 furnace is a directional solidification furnace from ECM Lab Solutions. It is ideal for G2 silicon ingot crystallization, up to 80 kg, and adheres to directional solidification process engineering requirements at laboratory or pilot scale. The PV80 furnace is available with Crystalmax® cast-mono technology and is designed with a three-zone thermal set-up. This set-up enables high reliability, reproducibility, and flexibility in the process growth of silicon ingots. The furnace is user friendly and designed specifically for research and development.
