Product Overview

Large muffle furnace designs steel housing, quality ceramic fiber insulation chamber with powerful heating elements, fast heating and cooling, low energy consumption, intelligent PID temperature controller with max temperature up to 1800 degree C. Large muffle furnace is ideal for heat treating, reacting studies, sintering processes, and ceramic firing on midium-sized samples.

Main Features
  • Tmax 1400 °C
  • Large muffle furnace type, electric heated, floor standing
  • Steel structure with fan cooling for low surface temperature
  • Fiber-insulated chamber for maximum temperature stability and uniformity
  • Powerful Silicon carbide as heating elements
  • Programmable digital PID temperature controller
  • Long life type S thermocouple
  • CE certified, standard
Safety Measures
  • 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
