Personalization

Computerized Tool

KSL-1700X-GS is a CE certified box furnace designed for materials synthesis under inert gas atmosphere with temperatures up to 1700 ºC. The furnace consists of high-quality alumina fiber bricks and Molybdenum alloy heating elements with an 8"x 8"x8" heating chamber. A vacuum-sealed steel chamber with water cooling jacket as well as the vacuum & gas flow control system enables material processing under inert gas atmosphere.


SPECIFICATIONS
Furnace Structure
  • Double layer stainless steel structure for maximum vacuum and safety
  • Spring loaded pressure relief valve installed on the furnace provide protection against chamber over-pressurization.
  • Water cooling front door and air cooling shell.
  • Built in the vacuum pump and two-channel gas flowmeters, pressure gauge needle valves.
Inside Chamber Size 

  • Heated chamber: 200 x 200 x 200 mm (8x8x8 inch), 8 Liter.
  • Energy saving 1800 grade fibrous alumina insulation.
  • High purity Al2O3 coating.

Thermocouple

two B type thermocouples (control thermocouple and secondard alarm thermocouple)

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 pcs Mo Alloy coils (can only be used under inert gas, Ar is preferred; cannot be used under air or oxygen at the temperature > 300°C).
                 

Temperature Control

  • PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired, current limiting resistor.
  • 30 programmable segments for precise control of heating / cooling rate and dwell time.
  • Over temperature protection and thermocouple failure alarm functions allow operation without attendant(s).
  • +/- 1ºC temperature accuracy.
  • RS485 Communications Port.
Temperature controller (optional)

  • MTS02-Y Temperature control software kit (for YD518P series controllers) + brand new 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 Temperature Controller which is fully compatible with LabVIEW with +/- 0.1oC accuracy.   This package includes a Eurotherm programmer, a communication cable (RS485 - USB) and a software CD.

Pressure Relief Valve

Spring Loaded Type Pressure Relief Valve
  • Cracking pressure is manufacturer pre-set at 0.066Mpa (relative pressure value).
  • Valve close pressure: 0.03Mpa (relative pressure value).
  • Max. Temperature 200ºC.
  • 35mm O.D barb fitting for gas exhaust.

Gas Flow Control and

Vacuum Valve
  • Two flow meters (#1: 0~8L/min; #2: 0~4L/min) are installed on the front panel of the furnace.
  • One heavy duty vacuum pump (CE certified) is built on the bottom of the furnace.  
  • Optional: You may order a (UL certified) pump at extra cost (Pls click the right picture below to see specs).
              ( CE certified )                ( TUV certified )
Water Cooling
  • A 16L/min recirculating water chiller is installed in bottom of furnace for cooling furnace sealing flange (CE certified only)
  • MET Certification (UL 1450) for water chiller is available upon request at extra cost, please contact our sales representatives for a quote.

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.)

Compliance

  • CE Certified for the furnace, vacuum pump, and water chiller.
  • All electronic parts in the furnace are UL or MET Certified.
  • UL / MET / CSA Certification is available upon request, additional charges will apply.                      
  •       

Application Notes

  • For preserving the longevity of the furnace components, we recommend the heating rate not to exceed 5 °C /min.
  • The cooling rate shall also not exceed 5 °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.

Warnings

  • ATTENTION: Any damages caused by the use of corrosive and acidic gasses are not under the coverage of MTI One Year Limited Warranty.
  • In order to prevent oxidation/corrosion damages to the Mo heating elements, it is necessary to keep a constant inert gas (Ar preferred) flow throughout the entire process. This is the most effective way to carry out any by-products.
