DSS™450HP

DSS™450HP Ingot Casting Furnace GT Advanced Technologies’ DSS450HP furnace delivers cost-effective and reliable multicrystalline ingot growth to helpcustomers lower the cost of PV manufacturing.

The DSS450HP includes a thermally optimized, second-generation, five-sided hot-zone for improved efficiency that can grow significantly faster silicon ingots averaging 52 hours — resulting in 15 percent more throughput. Because the DSS450HP has the same dimensions as the DSS450, current DSS450 users can easily migrate to the DSS450HP with a simple field upgrade kit. As a leading provider of PV manufacturing technology and services with over 3,000 DSS systems in the field, GT Advanced Technologies delivers proven value and a high return on investment.

Key advantages include:

• Cycle time down to 52 hrs*
• Mass ingot yield greater than 65%*
• 3,000 systems of experience ensures trouble free production ramp
• Furnace Output > 8MW per year (assumes 16 percent efficiency from156 mm cell lines)
• Fully automated and guaranteed process
• Patented crucible coating process
• Capability to process low and high quality feedstock
• Bottom-load process chamber adds operating convenience
• Upgrade kits available for DSS™240 and DSS450
