Pillar Delivers Six (6) Induction Systems to Silicon Carbide (SiC) and Pyrolytic Graphite Coating Producer

Pillar Induction has commissioned six (6) new induction heating systems used in the chemical vapor deposition (CVD) process for the production of silicon carbide (SiC) coated graphite products used in the aircraft / aerospace, industrial and semiconductor industries.

The new landmark installation consists of six (6) Pillar MK-8 power supplies consisting of five (5) 125 kW and one (1) 300 kW, providing nearly 1000kW of power.  Each system utilizes a pyrometer controlled temperature feedback to monitor the temperature of large diameter graphite susceptors which are heated to temperatures in excess of 1100°C.  The induction coils were designed by electrical and thermal 3D modeling to provide a  5°C uniformity along the heated length and diameter of the susceptor.

A closed pressurized water cooling system was provided to cool the power supplies and coil assemblies.  The water cooling system included a single pump station sized for current and future production needs.  Upon installation, the equipment and coils performed flawlessly to specification increasing the overall quality and productivity of each work cell. 

Pillar Induction is based in Brookfield, WI USA.  More information can be found at www.pillar.com
