Factory price of 1400.C vacuum atmosphere muffle furnace with gas
A.vacuum atmosphere muffle furnace can protect material from
oxidation and decarburization with flowing Nitrogen, Argon and
other inert gas.
B.vacuum atmosphere muffle furnace is an ideal heat treatment furnace
for sintering, reducing with inert-atmosphere in the labs of
university, Research Institution and industrial company.
Advantage of vacuum atmosphere muffle furnace

2. Temperature’s profile for your reference as below.( for example: 6 segments)
|Working temperature||Product Pictures||Heating elements||Characteristics|
|W T≤1200C||Fe-Cr-Al-Mo wire||Compared with the ordinary iron chromium aluminum wire resistance,
higher temperature and more durable|
|W T≤1400C||SiC heater||Using high temperature, anti-oxidation, corrosion resistance, long
life, small deformation, easy installation and maintenance.|
|W T≤1750C||MoSi2 heater||Suitable for ultra high temperature heating, long service life,
high calorific value and economic price|
4. Trouble shooting for typical Problems
Open Power Lock, no power
|Fuse (4A) in control panel is broken|
Check control panel, and replace
Green Power indictor is off,
but Red open circuit indicator
Fuse ( 50A) in main power
circuit is broken
Open the cover of front panel
and replace the fuse
No current shows in meter , but
has Max. Voltage
|Heating element broken|
Find broken heating rod, and
Controller display panel
SV shows“ OraL”
|Thermal Couples broken||Replace Thermal couples ( B type )|
Controller display panel
SV shows“ HI AL”
Furnace temperature >
1700C, Protection from Alarm
Cool furnace down, and find
reason why temperature is so high
( program setting may be wrong)
Power and heating element are OK, but furnace can’t be
controlled by program.
|Controller or related circuit may be damaged||Heck controller.|
Program running, but furnace can not be heated,
or real temperature is far behind the setting value
oPL or oPH value is too low
due to local voltage lower or frenquency different
Incraese “oPL” and “oPH” value till
current meter shows “ 120 A – 140A”, and program runs smoothly
|During heating below 300C, the temperature value ( PV) is not
stable, and doesn’t match with setting program (SV)||It is normal because the furnace comes with a high temperature
thermocouple, which is not sensitive at temperature below 300C|
Don’t worry. Let the furnace heat to
300C, then thermocouple will functionstably with program. If the PV valueat 300C is still less than that of SV, youmay need to increase OPL value a little.
