The Czochralski-puller is for mass production of silicon crystals up to 230mm diameter with the use of 22/24“ crucibles. The system can handle silicon melts up to 180 to 220 kilograms, producing ingot lengths between 2,800 and 2,900mm with 8“ or 9“ ingot diameters. The pull speed is stated by the company as 1.1mm/minute and it can go up to 1.5mm/minute with active crystal cooling. There is a new contact free crucible drive unit and a modular lifting unit. There are several optional features such as Active Crystal Cooling for reduced cycle time and optional SiO filtering unit with extended maintenance cycles among others available as well. PVA TePla AG has also stated that the new product has been produced with a reliable safety concept.
