An Unprecedented Offering By Order of SunEdison: A Complete Sale of its World Class Polysilicon Plant Operations in Merano, Italy.

This plant has consistently upgraded its operations to the highest state of the art production capacity standards.

  • Approximate Total Property: 102,475 mq
  • Approximate Covered Area: 32,635 mq
  • Approximate Open Area: 60,365 mq

The plant is an integrated facility starting from chlorosilane production and ending in polysilicon production for PV and EG applications.

Technological Highlights:

  • All CVD reactors (12, 18, 36 and 54 rods) have been designed by SunEdison.
  • TCS and STC purity is assured by a proprietary patented reactive distillation technology, very effective in removing Boron but also Posphorous and other metals.
  • The overall process is designed and operated to handle DCS formation and allow to feed TCS + DCS to the CVD reactors.
  • STC converters are designed internally and assure high STC conversion rate and low energy consumption.
  • The Front End has been designed and constructed by Evonik Degussa AG.

Installed Capacity:

  • Technical Grade Chlorosilanes:
  • Up to 25,000 Metric Tons Annually
  • Trichlorosilane Electronic Grade for Epitaxially grown silicon:
  • Up to 600 Metric Tons Annually
  • Siemens Based Polycrystalline Silicon:
  • Up to 4,000 Metric Tons Annually – Photovoltaic Grade
  • Up to 1,850 Metric Tons Annually – Electronic Grade for Microelectronics
