The Nabertherm Gas Supply System 4 is a professional, “Made in Germany” safety solution designed for operating tube furnaces with a **Hydrogen (H2) atmosphere** starting from ambient (room) temperature. This advanced system allows for the safe handling of flammable gases in a laboratory environment.
During operation, the system ensures a slight overpressure of approx. 30 mbar in the working tube to prevent air ingress. The hydrogen exhaust is safely burnt off in a monitored exhaust gas torch. The entire process—including pre-purging, hydrogen inlet, operation, and post-purging—is managed automatically by a Safety PLC control system with a touch panel. In the event of any malfunction, the system immediately switches to a safe status and purges the tube with nitrogen.
Standard Equipment:
- “Made in Germany” Safety: Engineered for safe operation with flammable gases (Hydrogen).
- Room Temperature Operation: Allows H2 atmosphere starting from ambient temperature.
- Safety PLC: Integrated safety control system with a touch panel manages all process steps automatically.
- Gas Panel: Includes gas supply control for Hydrogen (H2) and Nitrogen (N2).
- Exhaust Torch: Features a gas torch with temperature monitoring to safely burn off exhaust hydrogen.
- Automatic Purging: Includes an emergency purge container for Nitrogen to flush the system instantly in case of fault.
- Safety Sensors: Equipped with excess pressure monitoring and an over-temperature limiter.
- Automated Switching: Segment-related switching on/off via magnetic valves.
You can further customize the Gas Supply System 4 for specific process requirements, such as precise flow control or alternative gases.
Available Options & Accessories:
- Mass Flow Controllers: Upgrade to program-controllable mass flow controllers (MFC) for precise, automated regulation of gas flow rates.
- Alternative Gases: Panels available for operation with other flammable gases or additional non-flammable gases.
- Bottle Pressure Reducer: For safe connection to high-pressure gas cylinders.
- Closed Loop Cooling: An air-water heat exchanger is available for the cooling water circuit (Note: Not available for RSRB and RSRC models).
