IF5319 (Discontinued) 1200C Bottom-loading Vacuum Furnace with Rapid Cooling VBF-1200X-E8

Furnace

• Double-layer steel casing with air cooling keeps furnace surface < 60℃
• Water-cooled vacuum flange for better vacuum seal and longer service life
• 8.5" ID Quartz chamber works under both vacuum and gas flow.
• Motor-driven bottom loading for large sample loading at ease.
• The electric sliding door is built to block thermal radiation when the heated sample is loading down
• An inert gas blow system is installed to quench heated samples faster
• Two precision temperature controllers are included: one for furnace temperature and another for monitoring temperature change of the sample stage

Power

• 208-240 VAC, 1 ph, 50/60 Hz.
• 3600 W (20 A power receptacle is required)
• A 10-foot power cable is included but without a plug

Working Temperature

• Fe-Cr-Al doped Mo heating elements.
• ≤1200℃ with inert gas
• ≤1000℃ continuous under vacuum
• Heating rate: 20℃/min max

Temperature Control

• Two 30-segment programmable temperature controllers are included.
• One for controlling furnace heating and one for monitoring sample stage heating and cooling
• Built-in automatic PID control with auto-tune, overheating, and T/C broken protection.
• ±1℃ temperature accuracy.
• Two K-type thermocouples are included
• RS485 communication port

Heating Chamber and Vacuum-Sealed Flange

• Quartz chamber size: 9" O.D. x 8.5" I.D. x 13.4" L (230 OD x 218ID x 340 H, mm)
• Effective heating area: 8.5" ID x 8.5" Depth (218 ID x 216 H mm, 8.6 Liter)
• The quartz heating chamber is replaceable.
• One 16L/min recirculating water chiller is included for cooling the flange

Vacuum and Gas Flow

• One KF25 port is built-in for the vacuum pump connection.
• One dual-stage rotary vane pump with KF25 below and one angle valve are included.
• One Pirani vacuum gauge (up to 10-4 torr) and a mechanical vacuum gauge is included.
• Pfeiffer 33 L/s turbopump is available for high vacuum operation up to 10-5 torr.
• One 5L flowmeter with1/4" gas inlet and outlet is included for atmosphere control.

Cooling Chamber

• The gas cooling system is built-in for faster cooling of a heated sample
• 4 gas blow tubes are installed in for corner of the cooling chamber. 
• The gas valve shall be opened before loading the heated sample down
• Once the sample stage is down, the sliding door must be closed immediately to insulate the radiation from the heating chamber.
• The cooling rate and temperature can be monitored via thermal couple in the sample stage.

Application Notes

• Quartz tube furnace is designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 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.
• Vacuum pressures in the furnace shall be used below 1000℃ under vacuum processing
• The furnace can be used for brazing of two flat samples via top dead weight under vacuum at <1000℃
