ECM Greentech offers directional solidification furnaces (DSS) from G1 to G8 available with CrystalMax® technology. Our furnaces design takes into account all the specifications of the PV industry:
  • Capability to produce high ingot quality suitable to process high efficiency solar cells
  • Optimized production cost due to high silicon feedstock yield
  • Fully automatic thermal cycle
  • Low maintenance cost, low electrical consumption
  • Bottom loaded furnace to simplify and to secure the loading/unloading operations
  • Three heating zones for the perfect melting/crystallization thermal control
  • Optimized heat extraction for high efficiency processes
  • Safety: Optimised design and process control (hardware and software) to take into account possible silica crucible breakage during cycle.
