Principle of Non-Oxygen Furnace

Non-Oxygen Furance Image

In a Non-Oxygen Furnace, oxygen present in the atmosphere is converted into carbon monoxide (CO) by reacting with carbon inside the furnace.
The emission of carbon from carbon structures is minimal and has no significant impact on the durability or performance.

TYPE

Theoretical Oxygen Concentration

Characteristics

Metal Muffle Type

Minimum 20 ppm

  • ·

    Common type

  • ·

    High likelihood of temper color formation

  • ·

    Severe deformation in brazed products

Non-Oxygen Type

Maximum 5 ppm

  • ·

    Optimized for atmosphere furnaces due to nearly oxygen-free conditions

  • ·

    Excellent for maintaining flatness; advantageous for heavier and larger brazed products

  • ·

    Minimizes deformation and brazing defects

Main Applications

  • Condensers for Air Conditioner (Residential, System, and Automotive)
  • Evaporators for Air Conditioner (Residential and Automotive)
  • Oil Coolers for Automotive
  • Radiators and Intercoolers for Tank
  • Heat exchangers for Electric Vehicle (EV) Battery

*The Non-Oxygen Furnace uses inert gases such as nitrogen (N₂) or argon (Ar) as the atmospheric gas to maintain an oxygen-free environment.
