UL Standard 1650°C High Temperature Hydrogen Atmosphere Box Furnace, (8x8x8", 8L) - KSL-1700X-H2


In stock
Item Number: KSL-1700X-H2
Transported by LTL Freight (Truck)

Personalization

KSL1700X-H2 is CE certified box furnace designed for material synthesis under dry hydrogen or inert gas (Ar and He) up to 1650 ºC. The furnace consists of high-quality alumina fiber bricks and Mo alloy heating elements with a heating chamber of 8"x 8"x8", as well as a vacuum-sealed steel case with water cooling jacket and automatic H2 burning system. It is an ideal tool for preparing new materials which require reducing atmosphere, such as phosphorous and Ti alloy and also heat treating materials under inert gas.

SPECIFICATIONS
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 burner, gas delivery valve will be shut down automatically    
Inside Chamber Size
  
  • Heated chamber: 200x 200x 200 mm (8x8x8 inch), 8 Liter
  • Energy saving 1800 grade fibrous alumina insulation
  • High purity Al2O3 coating
  • Warning: One Al2O3 fibrous door block is included. You must place the door block in the front the chamber to block heat radiation, otherwise, may damage seal ring at high temperature and cause hydrogen gas leaking

Temperature controller

Main Temperature Controller is used to set and run the 30-segment heating program and provides the 1-level temperature alarm protection. 
Secondary Temperature Controller reads the temperature from the secondary B type themoucple, monitors the temperature during all process and provides the 2-level temperature alarm protection.

Pressure Control 

  • The pressure sensor and pressure controller are installed. It reads the chamber pressure and controls the inlet and outlet gas valves respectively according 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 0.03Mpa. 




Heating Elements

  • 6 sets of Mo coils heating elements are built in, and replaceable 
  • The heating element of Mo coil is consumable parts which should be ordered separately if extra sets are required.  ( order  picture below left to order spare )
  • Heating element can be replaced by MsSi2 to run furnace under oxygen and air up to 1700°C (order picture below right  to order spare)
  • Warning:   Mo heating element can not be used under air or oxygen at the temperature > 300°C
                   

Temperature Control


  • FA-YD518P-AG temperature controller is included.
  • Proportional–integral–derivative control (PID control) and auto-tune function
  • 30 segments programmed with ramping, cooling and dwelling steps
  • Built-in over-temperature alarm and thermocouple failure alarm
  • +/- 1 ºC temperature control accuracy
  • Default DB9 PC communication port
  • MET Certified

Temperature controller (optional)

  • MTS02-Y Temperature control software kit (for YD518P series controllers) + 15" laptop package  is available at the options bar. Click for the detail information about the MTS02-Y software kit. 
  • You may upgrade the temperature controller to the Eurotherm 3504 Temperature Controller which is fully compatible with LabVIEW. This package includes a Eurotherm 3504 programmer, a communication cable (RS485 - USB) and a software CD. Click the pic below to view the full spec of Eurotherm 3504 temperature controller.           
Gas Flow Control and Vacuum Valve
  • 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 ( CE certified ) built in bottom furnace.  You may  choose a UL certified pump at extra cost ( Pls click picture below to see specs)
( CE certified )                ( TUV certified )
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 operation facility to alarm hydrogen leaking b accident.  If you can not find in a local store, please click the link below to order hydrogen detector from us at extra cost.
  •  Option Hydrogen detector to Enhanced safety for MTI Hydrogen Gas Tube Furnace
Water Cooling


A 58L/min recirculating water chiller is installed for cooling furnace sealing flange.

Application Notes

  • Please EXERCISE EXTREME CAUTION. H2 gas is highly flammable and explosive. H2 ignites at a temperature of 400°C, an explosion could occur when the hydrogen content reaches 4.0%-74. 2% in the air, please strictly follow the rules below to for safety operation.
  • Inert gas MUST be used to purge the furnace chamber to eliminate all the air before introducing the H2 gas.
  •  The pressure inside the chamber should ALWAYS be controlled at around 0.01Mpa above the standard atmospheric pressure during the entire heating process, otherwise, the oxygen in the air may backflow into the furnace chamber and cause the explosion in the worst case scenario.
  •  Pressure over 0.02Mpa (Relative Pressure) is strictly prohibited.
  •  ALWAYS place the furnace in a room with a 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.
  • Must be used under inert gas or hydrogen gas environment
  • For preserving the longevity of the furnace components, we recommend the heating rate not to exceed 10 °C /min.
  • 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.
  • Please click here to learn how to DIY gas purging system.
  • The refractory block must be inserted before closing door.
  • Please Click Underline to learn "Max. Working Temperature of Heating Elements of Tungsten, Tantalum,   Molybdenum  Under  Various Processing Gases".
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
