The PV80 furnace is a directional solidification furnace ideal for G2 silicon ingot crystallization up to 80 kg offered by ECM Greentec. It is adapted to process engineering requirements at laboratory or pilot scale. The PV80 furnace is designed with a three-zone thermal set-up that has been developed for Crystalmax® cast-mono technology. 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.
