Hydrogen Gas Box Furnace is a large box furnace designed for material synthesis under hydrogen or inert gas atmosphere up to 1700 ºC. The Hydrogen furnace consists of high-quality alumina fiber bricks and three sides heated Mo-alloy coil with a vacuum-sealed steel case with a water cooling jacket. This Gas furnace is an ideal tool for preparing new materials that require a reduced atmosphere。
HTVF-1700-A Hydrogen Gas Box Furnace is a large box furnace designed for material synthesis under hydrogen or inert gas atmosphere up to 1700 ºC with a chamber dimension of 400 x 400 x 400 mm. The Hydrogen furnace consists of high-quality alumina fiber bricks and three sides heated Mo-alloy coil with a vacuum-sealed steel case with a water cooling jacket and automatic H2 burning system. This Gas furnace is an ideal tool for preparing new materials that require a reduced atmosphere, such as phosphorous and Ti alloy, and also heat-treating materials under Ar gas.
Furnace Structure | Double-layer stainless steel structure for maximum vacuum and safety, which can ensure a positive pressure up to 0.06MP and vacuum up to -0.1Mpa Water cooling front door and air cooling shell Built-in pressure gauge, vacuum valves, and two gas float meters Built-in H2 burning control system --- if the controller detects no flame in the burner, the gas delivery valve will be shut down automatically |
Inside Chamber | Heated chamber: 400 x 400 x 400 mm, 65 Liter (Max) Energy-saving 1800 grade fibrous alumina insulation Sealed by stainless steel with water cooling Three sides heating (Left, right and back) to ensure the best temperature uniformity. SiC plate is installed on the bottom, which has 100kg, Max. loading |
Heating Elements | 9 sets of Mo coils heating elements are built-in and replaceable The Mo heating element is consumable. You may order spare element by click Pic. 1 below Warning: Mo heating element can not be used under air or oxygen at the temperature > 300°C The heating element can be replaced by 1900 grade MsSi2 to run the furnace under oxygen and air and Inert gases up to 1700°C , |
Power | 36 KW |
Voltage | AC 208 - 240V three phases (50/60 Hz) |
Current | 80 Amp (100 Amp air breaker is required) |
Continuous Working Temperature | 1650° C ( in H2 gas or Ar gas, not recommended under N2 gas ) |
Maximum Working Temperature | 1700°C (< 1 hr) ( in H2 gas or Ar gas, not recommended under N2 gas ) |
Heating Rate | 5°C / min |
Temperature Accuracy | +/- 0.1°C |
Temperature Control and Processing control | Temperature and processing control via touch screen computer, including Temperature control with +/- 1ºC accuracy. Two thermal couples are built-in: one for temperature control and one for safety monitoring 30 programmable segments for precise control of heating rate, cooling rate, and dwell time. Over-temperature protection by an independent controller Recording and display temperature profile during operation Processing control includes： Purging procedure for the furnace chamber Chamber pressure control Gas flow control Recording and display pressure profile during operation |
Gas Flow Control and Vacuum Valve | Gas Flow Control and Vacuum ValveTwo large flow meters (N2: 0~ 12L/min, H2: 0~12L/min) are installed in the front panel of the furnace. One for purging Inert gas prior to introducing H2 gas One for controlling H2 gas flow KF40 vacuum pumps built-in to connect a vacuum pump The vacuum pump may be needed, but not included |
H2 Gas Burning Control System | An ignition device already installed to incinerate flowing gas and detect burner temperature to ensure H2 burner is in working condition. If H2 does not burn properly, the controller will shut down the H2 gas delivery valve immediately. Warning: You must install a certified Hydrogen detector in operation facility to alarm hydrogen leaking b accident. Please click the link below to order a hydrogen detector from us at extra cost. |
Water Cooling | A 16L/min recirculating water chiller is installed a bottom furnace for cooling furnace sealing flange. |

Warranty | One-year limited warranty with lifetime support. (Consumable parts such as sample plates and heating elements are not covered by the warranty, please order the replacement at related products below.) ATTENTION: Any damages caused by the use of corrosive and acidic gases are not under the coverage of One Year Limited Warranty. Attention: A free course of safety operation training at the MTI field is required to purchase this furnace. A customer's side training is also available upon request at extra cost. If the users believe that they have sufficient experience and knowledge to handle the furnace in the dangerous or emergent situation, a liability release agreement must be signed at the purchase. HT Corp. is not responsible for any damages caused by misuse without safety operation training. Any damages caused by the corrosive and acidic gases are not under the coverage of the One Year Limited Warranty. |
Application Notes | The pressure inside the chamber should ALWAYS be controlled at 0.01-0.02 Mpa above the standard atmospheric pressure during the entire heating process, otherwise, the oxygen in the air may backflow into the furnace chamber and cause an explosion in the worst-case scenario. ALWAYS place the furnace in a room with the fume hood and a hydrogen detector installed. Good ventilation is necessary for the room in which place the furnace Exhausting Hydrogen gas in the room is forbidden. |
