15KW Induction Heating System with 5" Quartz Tube & Temp.-Controller up to 2200°C - SP-50KTC

MTI

SP-50KTC is a temperature-controlled induction heating/melting system with complete accessories. It is an ideal tool for melting and sintering new metallic alloys with max. 2200ºC and can be modified into a PVT (Physical Vapor Transportation) system or melt infiltration system.
The system includes an induction heater, 130mm O.D quartz tube with flanges & valves, graphite crucible & refractory assembly, 58L/m recirculating water chiller, 156L/min vacuum pump, and a mobile cart.

Temp. Controller & Thermocouple Precision digital temperature controller with automatic PID tuning.
30 segments programmable for controlling heating and cooling rate as well as dwell time.
Overheating & thermocouple failure protection.
+/- 3 ºC temperature accuracy.
Thermocouple: C type (1/4"x10" L), consumable
Continuous Working Temp. Range: 1000ºC~1900ºC
Max Working Temperature: 2200ºC (for less than 30 minutes) and 2000ºC for 2 hrs
Max. Heating Rate:
10ºC/second (1000ºC-1200ºC)
8ºC/second (1200ºC~1500ºC)

Graphite Crucible & Refractory liners High Purity Graphite Crucible: 2" OD x 1.57" ID x 4" Depth (4.3'' Height) is included. Max. Loading Capacity: Half of the total volume of the graphite crucible.
Note: Graphite crucible is consumable, please order a spare.
Optional: Specially designed graphite "Box" for accommodating single piece wafer substrate up to 1.5'' O.D x 1/8'' Thick is available upon request. It is an ideal wafer holder which can be inductively heated up and provide uniform heat treatment to the wafer inside.
The crucible for melt infiltration is available upon request.
Three-layer special design refractory liner can withstand temperatures up to 2200ºC.
Sealing Flanges & Quartz Chamber 130mm(OD) x 122mm(ID) x 360mm(L) Quartz tube is included.
Top Flange: Hinged type flange w/ 1/4'' T/C feedthrough, needle valve, and barbed fitting.
Bottom Flange: Stainless steel flange with a needle valve and KF-25 vacuum port.
KF25 angle valve & clamps and 1m SS bellows are included for connecting to the vacuum pump.
Pressure Sensor Anti-corrosive capacitance diaphragm gauge, measurement range up to 3.8x10E-5 torr
One 24V, 1A DC power adapter is included and ready to use.
Flow Meter Compact Direct Read Flow Meter, 100-1000 cc/min. with 1/4NPT
Accuracy: 4%
Pressure Relief Valve This valve is designed to release pressure at 0.02 MPa for safety concerns
Water Chiller (Optional) Temperature range: 5 - 30°C
Water Flow Rate: 58 L/min
Water Tank: 15 Liters made of stainless steel
Note: It is recommended to use a specific coolant to get the best performance. It is normal to wait a couple of minutes for cooling down after several trials of heating
Note: the input voltage for the water chiller is 220V
Vacuum Pump One 156 L/min Double-Stage Rotary Vane Vacuum Pump
Rate: 156 L/min up to 1E-2 torr vacuum
Max. Power Consumption: 400W
If you choose a high-speed turbo-pump, the vacuum level can reach 10e-5 torr
Heavy Duty Mobile Cart Structure: Steel Frame Mobile Cart
600mm(L) x 800mm(W) surface for placing Induction Heater & Quartz Tube with Flange
Protective Shield For Non-UL Certified version, a protective shield made of phenolic sheets will be provided.
For UL Certified version, a clear protective shield made of polycarbonate will be provided.
The protective shield is to be placed around the quartz tube to contain the shooting glass shards if accidents were to happen.
Compliance NRTL certification is available upon request at extra cost, please contact us for a price quote. Certify standards include:
Induction heater: UL61010-1 & UL499
Vacuum Pump: UL1450
Water Chiller: UL61010 & UL1995
Warning Attention: Protective inert gas must be continuously filled throughout during heating in order to protect the graphite crucible and C thermocouple.
The C-type thermocouple is consumable which is not covered under the limited warranty.
The Induction Melting System is designed to operate in low-pressure conditions (< 0.02 MPa)
Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSIG for safe operation.
Never heat the furnace while the gas release valve is closed. The pressure gauge must be used during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSIG to prevent unforeseeable damages.
Application Notes Melting time and temperature are related to materials, the crucible, refractory insulation, etc.
