GCF1700 Controlled Atmosphere Muffle Furnace (1700°C Max)

The GCF1700 series controlled atmosphere muffle furnaces are engineered to provide precise control of temperature and atmospheric conditions for demanding high-temperature processes. Capable of reaching 1700°C, these furnaces are ideal for a variety of laboratory, industrial, and research applications that require a controlled environment with high thermal efficiency.

Key Features:

• High-Quality Construction:

  • Mitsubishi (Japan) high-grade 1800 Morgan polycrystalline alumina fiber is used for the furnace cavity, ensuring superior insulation and energy efficiency.
  • The furnace uses Molybdenum Silicide (MoSi2) heating elements, which provide excellent thermal stability and high-temperature resistance.
  • The furnace features a double-walled steel internal housing to minimize heat loss and improve efficiency.

• Advanced Temperature Control:

  • Eurotherm 3204 (UK) or Shimaden FP93 (Japan) multi-segment controllers, offering up to 50 segments of ramp and dwell programming, are available to provide precise temperature control.
  • The furnace also includes built-in digital communications ports and USB adaptors, allowing remote control and monitoring via PC. Test results can be saved or exported for further analysis.
  • The temperature control system offers ±1°C precision, ensuring consistent results.

• Controlled Atmosphere:

  • The furnace supports a variety of gases, including air, Nitrogen (N2), Argon (Ar), CO2, He, Ne, and Hydrogen (H2) up to 5%.
  • The gas inlet/outlet features 1/4" hose barb with BSPT threads for easy integration with external gas flow systems.
  • Multiple gas inlets and outlets are fitted with stainless steel ball valves and flow meters to control gas flow in and out of the furnace.
  • The furnace chamber is welded and oil-leak tested to ensure airtight sealing, with a high-temperature silicon gasket sealing the door.

• Vacuum and Pressure Control:

  • The furnace features a KF40 vacuum port for rough vacuum operations (down to 1000 Pa with hose barb connections, 100 Pa with flange connections).
  • Positive pressure is maintained at a maximum of 0.02 MPa (150 torr / 3 psi).

• Safety Features:

  • Overheat protection ensures the furnace shuts down if the temperature exceeds the set limit or if the thermocouple fails.
  • Power failure protection allows the furnace to resume operations once power is restored, ensuring the consistency of the process.
  • Built-in ammeter and dual voltmeters for monitoring electrical parameters.

• Cooling System:

  • A stainless steel water-cooling panel protects the furnace door’s sealing gasket during intense use, ensuring reliable operation even under high temperatures.

• Temperature Profiles:

  • The furnace supports multiple atmosphere processes in a single cycle, such as binder burnout in air and sintering under inert gas or rough vacuum conditions.

• Compliance and Warranty:

  • The furnace is CE compliant and can be ETL tested to UL and CSA standards (optional).
  • 1-year warranty covers parts and labor (excluding heating elements).
