1700C Single Zone High Temperature Tube Furnace

PRODUCT DESCRIPTION
1700C Single Zone Alumina Tube Furnace with 3 Channel Gas Mixer

Product Overview for 1700C CVD Tube Furnace

1700C series Gas controlled CVD tube furnace features intergrate two or
three gas channels, mixed gas controlled system, high alumina ceramic tube
with SS304 sealing flanges, heated by MoSi2 rods, Tmax 1700 degree C (1500C
under high vacuum level). Microprocessor-based self-tuning PID provides
excellent control with no overshooting and +/- 1 °C accuracy. Max vacuum
level could be reached to 10E-3 torr with molecular vacuum pump.

Safety Measures


Built-in ammeter and dual voltmeters for easy monitoring and
troubleshooting.
Overheat protection shuts down the tube furnace if temperature is outside of
acceptable range (refer to controller's manual) or when the thermocouple is
broken or malfunctions
Power failure protection resumes furnace operation right after the point of
failure when power is reestablished
Microprocessor based self-tuning PID control provides optimum thermal
process with minimal overshoot

Application Notes


Don't fill any explosive gasses such as Hydrogen or Methane into the furnace
tube without necessary safety controls and supervision
1700C tube furnaces with alumina tube are designed for use under vacuum and
low pressure; 0.2 bars / 3 psi / 0.02 MPa
To minimize the cracking rate of the ceramic tubes, please change the
position (mark four points on the tube) each batch
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
