Equipment Solutions for Multi-crystalline Ingot Production
GT Solar, a market leader in multi-crystalline growth technology, offers an evolving line of products designed to enhance performance and lower cost.
Our Directional Solidification System (DSS) furnaces, specialized furnaces that melt polysilicon and cast multi-crystalline ingots, are used to produce solar wafers, which are key components of solar cells. Our DSS furnaces are the most widely used in the solar industry, with more than 1,000 units shipped worldwide.
GT Solar’s key multi-crystalline growth products are:
GT-DSS450™
Premier Furnace for Photovoltaic Ingot Production
As the market leader in multi-crystalline furnace technology, GT Solar has already shipped worldwide more than 1,000 DSS furnaces for photovoltaic (PV) ingot production. GT Solar’s GT-DSS450, which enables our customers to grow larger multi-crystalline ingots at a lower cost than ever before, is the third generation design in our successful DSS manufacturing line.
The GT-DSS450 uses GT Solar’s patented crucible coating technology and process expertise, and it includes a production-proven coating process, which consistently produces crack-free ingots. What's more, when used in conjunction with our process expertise, auxiliary equipment and experienced field service engineers, the GT-DSS450 allows for the fastest production ramp-up in the industry.

GT-FZ100™
Float Zone System
Float zone is widely used by silicon manufacturers for analytical lab sample preparation and quality control. It plays an important role in assuring material purity, and is therefore an essential tool for solar and semiconductor grade silicon manufacturing.
GT Solar's GT-FZ100 float zone system has a long history of providing fast turn-around sampling and batch check for every reactor run, and for helping our customers ensure they are producing high quality silicon. The GT-FZ100's extreme reliability and stellar performance are evidenced by the many repeat orders we have received from satisfied GT Solar customers around the world.
