Apr. 30 /CSRwire/ - NASHUA, New Hampshire - GT Solar Technologies, a leading manufacturer of photovoltaic (PV) wafer, cell and module manufacturing equipment, will deliver multiple units of its GT-MX225 HEM furnace to SolarWorld AG subsidiary, Deutsche Solar. The value of the contract is in excess of $6 million.

The HEM furnaces will be installed at Deutsche Solar's Freiberg, Germany facility as part of the company's ongoing growth. The HEM (Heat Exchanger Method) is a crystal growth process for growing multicrystalline silicon ingots, which are further manufactured to produce electricity-producing solar cells, a key high growth product in the solar energy industry now growing over 35% annually.

"It required only a couple of growth runs to put the HEM furnace into full operational mode after installation." said Dr. Armin Mueller, Head of Production Crystallization and Research & Development at Deutsche Solar. "From then on we produced ingots that fully met our specifications."

"Our systems are proven and come on line quickly," explained Keith Matthei, Vice President of GT Solar. "Our experience in manufacturing PV equipment initially attracts customers like Deutsche Solar. They quickly develop confidence in the HEM manufacturing process, and that enables them to move on to focus on other critical business issues."

Deutsche Solar chose GT Solar's HEM furnaces after comprehensively testing one GT HEM furnace, which successfully displayed the proven capabilities of the equipment. GT Solar's HEM furnaces currently produce nearly one-third of the world's polycrystalline cells. The HEM furnaces' output, combined with the output of other silicon growth furnaces built by GT, yield close to 50% of the world's polycrystalline silicon material production of the solar industry.
