Advantage of Horizontal high temperature graphitization furnace:
1. The equipment can be equipped with special circulating water cooling system for intermediate frequency power supply and protective gas purification device. The special circulating water cooling system for intermediate frequency power supply can effectively reduce and eliminate equipment failures caused by cooling water quality problems, and ensure long-term normal production of equipment.
2. The power supply is optional. The company's complete sets of equipment have SCR intermediate frequency power supply and IGBT intermediate frequency power supply for customers to choose from. The SCR power supply is stable and reliable, which is easy to repair and maintain, and low maintenance cost. IGBT intermediate frequency power supply is energy-saving, environmentally friendly, small volume and cost-effective.
