STC-to-TCS Thermal Converters

STC-to-TCS Thermal Converters are critical equipment required in polysilicon production plants. A Thermal Converter is a large pressure vessel with a bell shaped (“bell jar”) enclosure that sits on top of a base plate.

The Thermal Converter system turns recovered silicon tetrachloride (STC) back into useable TCS by exposing the STC to high temperatures in the presence of hydrogen. The Thermal Converters are designed to contain the pressure and high temperatures that occur during the STC-to-TCS Thermal Conversion

High Efficiency Polysilicon Production

PPP Equipment Corporation (PPP-E) has designed high efficiency STC-to-TCS Thermal Converters to operate consuming the least amount of electricity, which lowers operating costs, reducing the cost of each kilogram of TCS produced.

PPP Equipment Corporation provides two different models of STC-to-TCS Thermal Converters designed to fit our customers’ plant. Both models of the PPP-E Thermal Converters provide 20% or higher single pass conversion of STC-to-TCS.

Flexibility of Use

PPP-E’s Thermal Converters use the same pressure vessel as PPP-E’s CVD Reactors. This makes it possible to use Thermal Converters in-line with the CVD Reactors. With only minor changes, a Thermal Converter can be changed into a CVD Reactor. PPP-E has changed a number of Thermal Converters over to CVD Reactors. This flexibility enables customers to quickly and easily change and expand their plants with little cost impact which is a benefit when adding Poly Plant Project’s (PPP’s) Cold Conversion process technology.
