15KW Induction Heating System with 8.5" Quartz Tube & Temperature-Controller up to 2000C - SP-85KTC

Please email for lead time

Product Options

Product Style:
SP-85KTC is a larger temperature-controlled induction heating/melting system with complete accessories, which includes a 15 KW 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 points < 2000ºC under protective gas environment.
WARNING: Please always keeps the pressure inside the vessel <0.02MPa relative to the atmosphere during the heating and inert gas filling. Please read the manual carefully, always wear a protective welding helmet, monitor, and properly control the pressure of the reaction vessel during the operation. Over pressurize the vessel can cause damage 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。 Never heat the furnace while the gas release valve is closed
    • The C-type thermocouple is consumable and is not covered by the manufacturer's warranty.
    • Please click here to learn how to set up the crucible for melting
    • The Induction Melting System is designed for use under vacuum and low pressure < 0.02 Mpa
    • 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.
