HT1700-H2 High Temperature Hydrogen Atmosphere Box Furnace is designed for material synthesis under dry hydrogen up to 1650ºC. The Hydrogen furnace consists of high-quality alumina fiber bricks and Mo alloy heating elements with a heating chamber of 200 x 200 x 200, as well as a vacuum-sealed steel case with a water cooling jacket and an automatic H2 burning system. Hydrogen Atmosphere Furnace is an ideal tool for preparing new materials that require a reducing atmosphere, such as phosphorous and Ti alloy.

SPECIFICATIONS OF Hydrogen Atmosphere Box Furnace
Furnace structure
- Double-layer stainless steel structure for maximum vacuum and safety
- 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 Size: Heated chamber: 200 x 200 x 200 mm, 8 Liter
- Refractory insulation material, Energy-saving 1800 grade fibrous alumina ceramic fiber board with High purity Al2O3 coating
Warning: One Al2O3 fibrous door block is included. You must place the door block in the front of the chamber to block heat radiation, otherwise, may damage the sealing ring at high temperature and cause hydrogen gas leaking
- Power: AC 208 - 240V single phase (50/60 Hz), 7.5 KW, 30 Amp (50 Amp air breaker is required)
Temperature of Hydrogen furnace
- Continuous 1600°C
- Max. 1650°C (< 60min)
- Accuracy: +/- 1°C
- Heating Rate: 5°C/min
- Thermocouple: two B type (control thermocouple and secondary alarm thermocouple)
- Temperature controller of Hydrogen Atmosphere Box Furnace: The main Temperature Controller is used for controlling the 30-segment heating program and provides the 1-level temperature alarm protection.
Secondary Temperature Controller reads the temperature from the secondary B type thermocouple, monitors the temperature during all processes, and provides the 2-level temperature alarm protection.
Pressure Control of Hydrogen Atmosphere Furnace
- The pressure sensor and pressure controller are installed. It reads the chamber pressure and controls the inlet and outlet gas valves respectively according to the pressure limit settings
- The pressure control can be used to perform the following functions:
Purging
Pressure control
High and Low-pressure protection
The pressure controllable range: -0.06 to 0.03 Mpa.
- Heating Elements: 6 sets of Mo coils heating elements are built-in and replaceable
The heating element of the Mo coil is consumable parts which should be ordered separately if extra is required. (click the pictures left to order spare)
The heating element can be replaced by MoSi2 heating elements to run the furnace under oxygen and air up to 1700°C.
Warning: Mo heating element cannot be used under air or oxygen at the temperature > 300°C
- Gas Flow and Vacuum Valve of Hydrogen Atmosphere Furnace:
Two large flow meters (N2: 0~3.5L/min, H2: 0~3.5L/min) are installed on the front panel of the furnace.
One for purging Inert gas prior to introducing H2 gas
One for controlling H2 gas flow
One heavy-duty vacuum pump (built-in bottom furnace to enhance the purging chamber.
H2 Gas Burning Control System and Option Hydrogen detector
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 the operation facility to alarm the hydrogen leaking accident. If you can not find it in a local store, please order a hydrogen detector from us at an extra cost
Option Hydrogen detector to Enhanced safety for HT Hydrogen Gas Tube Furnace
- Water Cooling OF Hydrogen Furnace
A 58 L/min recirculating water chiller is installed for cooling furnace sealing flange.
- 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
Application Notes of Hydrogen Atmosphere Furnace
Attention: A free course of safety operation training at HengTong 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 a dangerous or emergent situation, a liability release agreement must be signed at the purchase. Hengtong company 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.
