GT Solar International has won a $93.9m order from Taiwan-based polysilicon producer Powertec Energy for a complete suite of polysilicon production equipment and technology including SDR 400 reactors, hydrochlorination, filament and product processing equipment.

The equipment will be installed in Powertec’s new polysilicon facility, which is expected to begin production in 2012.

The company said the orders will be included in its backlog for the first-quarter ending 2 July.

Powertec Energy CEO Scott Kou said that GT Solar’s polysilicon technology and complete range of engineering services will allow the company to quickly ramp its plant to volume production while delivering the highest return on its investment.

According to the company, the SDR 400 CVD reactor has proven capability of producing over 400 metric tons annually (MTA) of polysilicon.
