Hydrogen Reduction
Tube Furnace

The Hydrogen Reduction Tube Furnace is engineered for high-temperature processes involving hydrogen or cracked ammonia gas, with a robust safety architecture and reliable performance at temperatures up to 1600°C. These furnaces are ideal for hydrogen reduction, sintering, debinding, annealing, and various thermal treatments in a reducing atmosphere. 

Optimized for Hydrogen Safety & Performance

Each furnace is designed with leak-tight ceramic tube assemblies, automated purge systems, and optional vacuum pre-treatment for oxygen removal—ensuring the safe and controlled handling of flammable gases. Customization options allow users to choose tube materials, dimensions, and pressure or vacuum systems based on specific process needs.
