A high-purity photovoltaic wafer and solar cell production facility located in the Batangas industrial zone, Philippines, required an automated vertical transfer solution to elevate bagged granular polysilicon raw materials directly into an upper-tier crystallization furnace feeder line. The process involves sealed 30 kg bags (measuring 330 mm x 230 mm x 260 mm) arriving from cleanroom bagging cells at a baseline elevation of 700 mm and elevating them to a 4,200 mm upper mezzanine discharge conveyor. Polysilicon raw materials demand high chemical purity, requiring equipment surfaces in direct contact with materials to eliminate heavy-metal contamination, surface dusting, and static charge accumulation.

To ensure non-stop raw material feed without contaminating solar-grade silicon stocks, the Gradin engineering team engineered a dedicated Polysilicon Raw Material Elevator configured as a Cleanroom Photovoltaic Conveyor. The system complies with the ASME B20.1 Safety Compliance standard for vertical material handling machines . Factory management integrated this Gradin continuous lifter alongside custom industrial continuous vertical lifters to automate their high-purity solar wafer manufacturing line.
