The PV20 furnace is a directional solidification furnace ideal for G1 silicon ingot crystallization up to 20 kg offered by ECM Greentec. It is adapted to process engineering requirements at laboratory or pilot scale. The PV20 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.
