OTF-1200X-S5-H2 Hydrogen Gas Tube Furnace with 1100°C Max Temperature and 5″ Fused Quartz Tube Featuring Integrated H2 Leak Detection and Safety System
The OTF-1200X-S5-H2 is engineered for precise heat treatment of materials sensitive to oxidation, utilizing a controlled hydrogen atmosphere. This single-zone tube furnace accommodates a 5-inch diameter fused quartz tube, providing a chemically inert and thermally stable environment for processing samples up to 1100°C. Its design supports continuous operation at 1000°C and short-term operation at 1100°C, enabling a broad range of thermal treatments.
Safety and operational reliability are paramount in this model. It integrates a Honeywell UL-approved hydrogen gas detector that continuously monitors for leaks. Upon detecting hydrogen concentrations exceeding 20% of the lower explosive limit, the system automatically triggers an alarm, cuts off the hydrogen supply, shuts down heating elements, and initiates nitrogen purging to mitigate hazards. Additionally, the furnace safeguards against air backflow during power outages, ensuring safe shutdown procedures.

대표적인 적용 분야
This furnace is ideal for heat treating oxidation-sensitive materials such as metal powders, thin films, and ceramics under controlled hydrogen or inert atmospheres. It supports processes requiring precise temperature control and safety measures against hydrogen hazards, including reduction reactions and annealing in research and industrial laboratories.
구성 및 작동 안내
The furnace includes two fibrous ceramic thermal blocks for radiation isolation, which must be fully inserted before heating. Quartz blocks are available optionally for cleaner environments and improved vacuum efficiency. The system requires installation under a fume hood (not included) for safe gas handling. Optional accessories include a water-cooled flange and a PC control module (MTS02-B) for advanced operation. A two-stage pressure regulator must be used on hydrogen cylinders to maintain safe gas pressure below 3 PSI. Gas flow rates should be limited to under 200 SCCM to prevent thermal shock to the quartz tube. The furnace is designed for vacuum and low-pressure operation below 0.12 atm absolute pressure, with vacuum operation limited to 1000°C maximum.
