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