15KW Induction Heating System with 8.5" Quartz Tube & Temperature-Controller upto 2000ºC - SP-85KTC

Please email for lead time
Item Number: SP-85KTC


Upgrade to Eurotherm Temperature controller
SP-85KTC is an MET standard larger temperature-controlled induction heating / melting system with complete accessories, which includes a 30KW Induction Heater, 8.5" (216mm) O.D Quartz Tube with Hinged type Flanges & Valves, Graphite Crucible & Refractory Assembly, 58L/m Recirculating Water Chiller, Vacuum Pump, and Mobile Cart. It is an ideal tool for growing crystal, melting and sintering new metallic alloys with melting point < 2000ºC (under protective gas environment).
 WARNING    Please always keeps the pressure inside the vessel <0.02Mpa during the heating and inert gas filling. Please read the manual carefully, always wear protective welding helmet, monitor and properly control the pressure of reaction vessel during the operation. Over pressurize the vessel can cause damages to the quartz tube, flange, and even personal injury.

    • Attention: Protective inert gas must be continuously filled throughout the experiment in order to protect the graphite crucible and C thermocouple.  The gas flow rate should be limited to < 200 SCCM ( or 200ml/min )
    • The C type thermocouple is comsumable which is not covered under our limited manufacture warranty.
    • Please click here to learn how to setup crucible for melting
    • Melting time and temperature are related to materials, crucible, refractory insulation, etc. If you do not know whether the induction heater can melt your sample or not, please contact our engineer for consulting. 
    • The Induction Melting System are designed for using under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI 
    • 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. 
    • Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
    •  PVT ( Physical Vapor Transportation ) system for growth bulk SiC crystal by changing a suitable crucible, please Pic below or ask our engineers how to
    • This furnace can be modified as RTP ( rapid thermal processing  ) and HPCVD system with the gas  delivery system.  Please click the link below to see how.  If you have any special requirement, please let us know
