      1. Operation Temperature: 1100℃ (1200℃ for short time). 
      2. Maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient alumina fiber ceramic insulation.
      3. Heavy duty double layer structure with cooling fan. Lower temperature in outside case. 
      4. PID automatic control via current limiting phase angle fired the resistor, e.g. SCR (Silicon Controlled Rectifier).
      5. Power control with 51 segments programmable
