1200°C Controlled Atmosphere Muffle Furnace (GCF1200 Series)

The GCF1200 series controlled atmosphere muffle furnaces are designed to offer precise temperature control and the ability to work in specific atmospheres, ideal for applications requiring exact temperatures and controlled environments. These furnaces are equipped with Kanthal A1 heating elements and Mitsubishi polycrystalline alumina fiber insulation, ensuring reliable performance even in the most demanding settings.

Key Features:

• Controlled Atmosphere:

  • Multiple gas inlets and outlets with stainless steel ball valves and flow meters to control inbound and outbound gas flows. These outlets can be ignited to burn off gases as needed.
  • The furnace chamber is welded and oil leak tested to ensure complete air-tightness, essential for maintaining an accurate atmosphere inside.
  • A vacuum port (KF40) is included for pre-vacuuming the chamber, which is particularly useful when using inert or protective gases.
  • Gases that can be used include air, N2, Ar, NO2, CO, CO2, He, Ne, and rough vacuum, with hydrogen up to 5%.

• Temperature Control:

  • The furnace is controlled by either an Eurotherm 3204 controller (UK) or Shimaden FP93 controller (Japan). Both options provide precise temperature management and come with the ability to program ramp and dwelling cycles.
  • PID self-tuning microprocessor control optimizes the thermal process with minimal temperature overshoot.
  • Type K thermocouple for accurate temperature measurement, ensuring ±1°C precision.

• Gas Atmosphere and Safety:

  • The gas inlet/outlet is fitted with 1/4" hose barb and BSPT threads to easily connect to the appropriate gas supply system.
  • The furnace features an overheat protection system that shuts down the unit if temperatures exceed the acceptable range or if the thermocouple fails.
  • Power failure protection ensures that the furnace resumes operation once power is restored, avoiding disruptions in the process.

• Built-in Monitoring and Control:

  • Ammeter and dual voltmeters are integrated for real-time monitoring and troubleshooting.
  • Computer interface allows remote control and monitoring via a PC, and users can save or export test results for analysis or documentation.

• Atmosphere Options:

  • The furnace supports multiple atmosphere processes in a single cycle. For example, binder burnout in air and sintering under a vacuum or inert gas can be done within one continuous process.
