Crystallization plant and crystallization process

The invention relates to a crystallization system with electric heating means, the heater positionable magnet module (100) is formed as a crucible to a wall (41) of a crucible (40) around executed. In an interior space (10) of a first heater-magnetic module (100) is a second, also to the crucible wall (41) of the crucible (40) provided around positionable heater magnet module (200). Further, a crystallization process is provided.
