DSS™450HP

Directional Solidification System
Increased Productivity Lowers Cost of Manufacturing
Distinguished by its proven production technology, GT Advanced Technologies’
DSS™450HP furnace sets the standard for cost-effective, reliable
multicrystalline ingot growth and helps customers lower the cost of PV
manufacturing. The GT Advanced Technologies 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 DSS™450, current users can easily migrate
to the new DSS450HP with a 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.

Existing DSS450 and DSS240
customers can easily upgrade to
the new DSS450HP platform with a
