Exo Gas Generator

Noxair Engineering’s Exo Gas Generators deliver consistent, high-quality protective atmospheres essential for a wide range of heat-treatment and metallurgical applications. Designed for reliability, energy efficiency, and long-term performance, our systems ensure stable furnace atmospheres for non-ferrous, ferrous, and specialty metal processing.

Using controlled combustion of hydrocarbon fuels, our generators produce a tailored gas mixture ideal for non-oxidizing, inert, or carbon-rich environments. While natural gas and propane are the most commonly used fuels, our flexible design allows operation on MAP gas, kerosene, fuel oil, or other combustible fuels based on customer requirements.

Lean Exo Gas Generators For Non-Ferrous Heat Treatment

Lean Exo Gas is produced through precise low sub-stoichiometric combustion, resulting in a clean, low-reactivity atmosphere with reduced CO and H₂ levels.
Ideal for:

• Bright annealing of aluminum and copper
• Non-ferrous metal heat treatment
• Applications requiring a neutral, non-oxidizing atmosphere

Rich Exo Gas Generators For Steel, Brazing & Annealing

Rich Exo Gas is generated using a higher sub-stoichiometric air-to-fuel ratio, producing a CO- and H₂-rich environment with strong reducing and carbonizing capability.
Ideal for:

• Heat treatment of steel components
• Brazing, annealing, and sintering
• Processes requiring higher carbon potential and superior metallurgical control
