Gas Supply System 4
When equipped with different gas supply systems, most tube furnace product lines can be adapted for operation with non-flammable or flammable gases or for vacuum operation.
Function and equipment
Gas Supply System 4 for Hydrogen Applications in Tube Furnaces from Room Temperature
Gas supply system 4 allows operation with a hydrogen atmosphere starting at ambient temperature. During hydrogen operation, a pressure of approx. 30 mbar is ensured in the working tube. At the gas outlet the hydrogen is burnt off in an exhaust gas torch. Equipped with a safety PLC control system, pre-purging, hydrogen inlet, operation, fault monitoring and purging at the end of the process are carried out automatically (with at least five times the volume of the tube). If a malfunction occurs, the tube is immediately purged with nitrogen and the system is automatically switched to a safe status.
