MERRIMACK – Add two new customers to GT Solar’s base of worldwide consumers looking for productive polysilicon production equipment.

GT Solar International Inc. announced Tuesday that it received $81.7 million in new orders for polysilicon production equipment and technology, including GT’s hydrochlorination equipment used for the production of TCS, from two new customers in Asia.

The orders will be included in GT Solar’s backlog for its first quarter of fiscal year 2012, which ended Saturday .

GT Solar is a global provider of polysilicon production technology, as well as sapphire and silicon crystalline growth systems and materials for solar, LED and other specialty markets.

GT Solar’s polysilicon production equipment includes the industry’s most productive and energy efficient CVD reactors and a full range of technology including hydrochlorination, filament and product processing equipment to provide a complete, low-cost end-to-end production solution.

GT Solar is also in the middle of expanding its highly successful niche building furnaces used to make silicon and sapphire crystal forms for photovoltaic systems.

The company acquired Salem, Mass.-based Crystal Systems Inc. in July 2010 and began expansion there in August, doubling employment there to 90 people and tripling its production, the company said.

Along with its ongoing expansion, GT Solar plans to change its name to GT Advanced Technologies this summer.
