1750°C Max Controlled Atmosphere Muffle Furnace w/ PC Interface 20X16X16

GCF1750 Controlled Atmosphere Muffle Furnace (1750°C Max)

The GCF1750 series controlled atmosphere furnaces are designed for applications that require high-temperature processes with precise control over the atmosphere. These furnaces can reach up to 1750°C, making them ideal for research, industrial, and laboratory environments where exacting conditions are needed for materials processing, sintering, and other heat treatment applications.

Key Features:

• Superior Construction:

  • The furnace chamber is built with Mitsubishi (Japan) high-quality 1800 Morgan polycrystalline alumina fiber, offering excellent insulation and heat retention.
  • Molybdenum Silicide (MoSi2) heating elements are used for their ability to withstand high temperatures and provide reliable heating performance.
  • A double-walled steel internal housing reduces heat loss and enhances energy efficiency.

• Advanced Temperature Control:

  • Eurotherm 3204 (UK) or Shimaden FP93 (Japan) controllers provide precise temperature regulation with up to 50 segments for ramping and dwelling, ensuring accurate thermal processes.
  • These furnaces feature built-in digital communication ports and USB adaptors for remote control via PC, allowing users to monitor the furnace and export test results easily.
  • Temperature control precision is within ±1°C, ensuring consistency in every cycle.
  • Maximum heating rate of 15°C/min allows for rapid thermal cycling when needed.

• Controlled Atmosphere:

  • The furnace supports a wide range of gases, including air, Nitrogen (N2), Argon (Ar), Helium (He), Neon (Ne), Hydrogen (up to 5%), and rough vacuum.
  • Multiple gas inlets and outlets with stainless steel ball valves and a flow meter allow precise control of the atmosphere within the chamber.
  • The furnace chamber is welded and oil leak tested to ensure air-tightness, and the door is sealed with a high-temperature silicon gasket.

• Vacuum and Pressure Management:

  • The furnace is equipped with a KF40 vacuum port, allowing users to pre-vacuum the chamber before introducing inert or protective gases.
  • Positive pressure inside the furnace is capped at 0.02 MPa / 150 torr / 3 psi.

• Safety Features:

  • Overheat protection automatically shuts down the furnace if the temperature exceeds safe limits or if the thermocouple malfunctions.
  • Power failure protection ensures the furnace resumes operations seamlessly once power is restored.
  • Built-in ammeter and dual voltmeters are included for easy monitoring of electrical parameters.

• Cooling System:

  • A built-in stainless steel water-cooling panel protects the furnace door’s sealing gasket, particularly during extended operations at high temperatures.

• Multiple Atmosphere Processing:

  • The furnace allows users to perform multiple atmosphere processes within a single cycle, such as binder burnout in air and sintering under an inert gas or rough vacuum environment.

• Compliance and Warranty:

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