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.

Voltage

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. 40 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.

Warranty

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.
