KSL-1200X-H2 1200°C Hydrogen Atmosphere Box Furnace with Five Heated Sides and 64L Chamber
The KSL-1200X-H2 furnace is engineered for advanced material synthesis and heat treatment processes requiring a controlled hydrogen atmosphere at temperatures up to 1200°C. Its design addresses the need for uniform heating and safe operation under reducing gas environments, making it suitable for preparing sensitive materials such as phosphorous compounds and titanium alloys.
This box furnace features a spacious 64-liter chamber measuring 400 mm on each side (approximately 16″x16″x16″) and employs five heated sides—left, right, bottom, back, and front—to achieve enhanced temperature uniformity compared to conventional three-sided heating. The heating elements are made from Kanthal Fe-Cr-Al alloy, rated for continuous operation up to 1300°C, ensuring reliable performance within the maximum working temperature of 1200°C.
Wichtigste Merkmale
- Five-sided heating configuration for uniform temperature distribution within ±1°C over a 250 mm cubic zone.
- Vacuum-sealed double-layer stainless steel structure with water-cooled front door and air-cooled shell for safety and durability.
- Integrated hydrogen burning control system with automatic gas shutoff upon flame failure detection.
- Built-in pressure gauge, vacuum valves, and dual gas flow meters for precise control of inert and hydrogen gases.
- Energy-efficient insulation using 1500-grade fibrous alumina and reflective Al2O3 coating.
- Temperature controlled by a PID FA-YD518P-AG controller with auto-tuning and programmable ramp/cool/dwell steps.
- Maximum sample loading capacity of 35 kg within the heated chamber.

Typische Anwendungsbereiche
Ideal for synthesizing materials that require a reducing hydrogen atmosphere, such as phosphorous compounds and titanium alloys. Also suitable for heat treatment under various gas atmospheres including inert, oxygen, and non-flammable gas mixtures. The furnace can be adapted for chemical vapor deposition (CVD) processes with customized gas mixtures.
Hinweise zur Konfiguration und zum Betrieb
The furnace includes a built-in hydrogen burning control system that automatically shuts off hydrogen supply if flame failure is detected, enhancing operational safety. A water cooling jacket and air-cooled shell protect the furnace structure during operation. Users must install a certified hydrogen detector in the operating environment and ensure proper ventilation due to hydrogen’s flammability and explosion risk. The chamber must be purged with inert gas before introducing hydrogen, and internal pressure should be maintained slightly above atmospheric (0.01-0.02 MPa) to prevent air ingress. The heating rate should not exceed 10°C/min to preserve furnace longevity. Optional upgrades include advanced temperature controllers compatible with LabVIEW and software packages for enhanced process control.
