Vacuum Compact Tube Furnace with the Temperature up to 1800C

Model: AS-TF-1800C

Max. working temperature: 1800 Degree

Constant working temperature: 1750 Degree



1800C Vacuum Compact Tube Furnace 

The AS-VF-1800C tube furnace feature is made of Mitsubishi (Japan) high quality 1900 grade alumina fiber insulation and the famous Kanthal (Sweden) 1900 grade molybdenum silicide heating elements.The double walled steel internal housing helps minimize heat loss to exterior surface.

Furnace operation of the furnace body is controlled by Shimaden (Japan) 40-segment digital controller with built-in RS485 digital communications port and USB adapter, allowing the user to connect to a PC for remote control and monitoring of the furnace. You can also save or export test results. All our furnaces are CE compliant.


1.Compact, portable and lightweight design.

2.Standard package includes set of stainless steel vacuum sealing flanges with valves and pressure meter.

3.Dual flanges support ensures better sealing and longer tube life.

4.Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot.

5.Multiple atmosphere processes in a single cycle are possible (ex: binder burn out in air and parts sintering under rough vacuum or inert gas environment.)

6.Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.

7.Built-in computer interface.

8 .Long life type B thermocouple.


1.Overheating protection shuts down the furnace if temperature is outside of acceptable range (refer to controller's manual) or when the thermocouple is broken or malfunctions.

2.Power failure protection resumes furnace operation right after the point of failure when power is reestablished.

Warning! NEVER fill furnace with explosive gases, including Hydrogen, Carbon Monoxide and Methane.
