CF1750 Muffle Furnace

The CF1750 series muffle furnaces are high-performance units designed for precision heat treatment applications that require temperatures up to 1750°C (3182°F). These furnaces are suitable for a wide range of industrial and laboratory applications, such as metal sintering, ceramics, heat treatment, and other high-temperature processes.

Key Features:

• High-Quality Construction:

  • The furnace is equipped with Mitsubishi 1850 grade polycrystalline alumina fiber for high-efficiency insulation, ensuring excellent heat retention and minimal heat loss.
  • Molybdenum Silicide (MoSi2) heating elements are installed to provide precise and consistent heating.

• Advanced Temperature Control:

  • The Eurotherm (UK) digital temperature controller allows precise control of heating and cooling cycles, featuring a self-tuning PID that optimizes thermal processes with minimal overshoot.
  • The controller offers options for 8-segment (model 3204) or 50-segment (model 3504) programming, allowing for both ramp and dwell settings for complex thermal profiles.
  • The furnace includes long-life type B thermocouple (B or PtRh40-PtRh20 optional), known for its accuracy at high temperatures.
  • Built-in ammeter and voltmeters enable easy monitoring and troubleshooting of electrical systems.

• Safety Features:

  • Overheat protection: The furnace will shut down if the temperature exceeds the safe operating range or if the thermocouple malfunctions.
  • Power failure protection: The furnace automatically resumes operation once power is restored after an interruption.
  • ETL testing to UL and CSA standards (optional) and CE certification ensure the furnace meets international safety and quality standards.

• Dual-Wall Steel Housing:
  The furnace’s dual-wall steel housing minimizes heat loss to the exterior, ensuring better energy efficiency and a cooler outer surface for safer operation.
