Graphite Heating Systems need to maintain the desired temperature profile within the susceptor. This is absolutely critical in order to achieve maximum productivity. Therefore, Graphite Heating Systems ensure that precise power input to each zone of the susceptor is achieved by varying either or both the overall power level and the amount of time power is switched to a particular zone of the coil during each power distribution cycle of the system. This leads to increased yields of product over a given length hot zone. Graphite Heating Systems are ideal for CVD, CVI and carbon carbon composite applications.
