Product Overview for Laboratory Hydrogen Vertical Tube Furnace
PTV D40/300/14 is a highly customized CE certified OD40mm Hydrogen vertical tube furnace with complete vacuum sealing flanges. Furnace tube was build with alumina tube. The furnace equips with a auto PLC controlled ignition device on the top, when detect the H2 gas release from the outlet, it will automatically ignite the gas. The heating zone is heated by SiC rod up to 1400°C. It is an excellent furnace to process threadiness, powder, small steel parts materials under Hydrogen gas, and also can be used for nano or film growth by CVD.
Main Features
- Tmax 1400 °C
- Vertical tube furnace, Hydrogen gas atmosphere
- Dual steel structure, non-split furnace chamber built on a small trolley, easy to move
- Multiple atmosphere processes in a single cycle are available
- Fiber-insulated chamber with powerful SiC rod heating elements
- PLC controlled temperature setting interface and gas filling system
- Alumina tube with sealing flanges
- Long life type S thermocouple

Safety Measures
- Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
- Overheat protection shuts down the tube furnace if temperature is outside of acceptable range (refer to controller's manual) or when the thermocouple is broken or malfunctions
- Power failure protection resumes furnace operation right after the point of failure when power is reestablished
- Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot

Application Notes
- Don't fill any explosive gasses such as Hydrogen or Methane into the furnace tube without necessary safety controls and supervision
- 1400C tube furnaces with alumina tube are designed for use under vacuum and low pressure; 0.2 bars / 3 psi / 0.02 MPa
- To minimize the cracking rate of the ceramic tubes, please change the position (mark four points on the tube) each batch
- Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating
