Product Dimensions (mm)






Furnace Structure

1.      Double layer stainless steel structure for maximum vacuum and safety, which can ensure a positive pressure up to 0.06MP and vacuum up to -0.09Mpa

2.      Spring loaded pressure relief valve installed on the furnace provide protection against chamber over-pressurization.

3.      Water cooling front door and air cooling shell.

4.      Built in the vacuum pump and two-channel gas flowmeters, pressure gauge needle valves.

Inside Chamber Size


1.      Energy saving 1800 grade fibrous alumina insulation.

2.       High purity Al2O3 coating.


AC 220 - 380V single phase; 50/60 Hz

Continuous Working Temperature


Maximum Working Temperature

1700°C (< 1 hr)

Heating Rate

20°C / min

Temperature Accuracy

+/- 1°C

Heating Elements

1.    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).

2.    Optional: Heating elements can be replaced by MoSi2 to enable heat processing under oxygen and air atmospheres  up to 1700°C.

Temperature Control

1.      PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired, current limiting resistor.

2.      30 programmable segments for precise control of heating / cooling rate and dwell time.

3.      Over temperature protection and thermocouple failure alarm functions allow operation without attendant(s).

4.      +/- 1ºC temperature accuracy.

5.       RS485 Communications Port.

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. 

Water Cooling

• A 16L/min recirculating water chiller is installed in bottom of furnace for cooling furnace sealing flange.


One year limited warranty with lifetime support.

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.
• The refractory block must be inserted before closing door.
