Abstract

A heater bundle (12) includes a plurality of heater assemblies (18), at least one of the heater assemblies (18) including a plurality of heater units, at least one of the heater units defining at least one independently controlled heating zone. A thermal provision is configured to modify a thermal conductance along a length of the at least one heater assembly (18) to compensate for non-uniform temperatures within at least one heater unit. The heater bundle (12) includes a power supply device (14) including a controller (15) configured to modulate power to the independently controlled heating zone through the power conductors based on the determined temperature to provide a desired power output along a length of at least one heater assembly (18).
