Product Overview

Industrial Muffle Furnace features bigger volume, normally build in floor standing type, high alumina ceramic fiber insulated with powerful heaters, enables samples to be heat-treated at temperatures exceeding 1700°C (3092°F). Industrial muffle furnace is mainly designed for heat treatments on batch products / samples for industrial using.

Main Features
  • Tmax 1700 °C
  • Dual steel structure with fan cooling for low surface temperature
  • Fiber-insulated chamber for maximum temperature stability and uniformity
  • Powerful 1850# MoSi2 rods heating from two sides evenly give an improved temperature gradient
  • Programmable Digital Shimaden Temperature Controller
  • Long life type B thermocouple
  • CE certified, standard
  • Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
  • Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller’s manual) or when the thermocouple is broken or malfunctions
  • Power failure protection resumes furnace operation right after the point of failure when power is reestablished
  • Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot
