Atmosphere Controlled Muffle Furnace is a five-side heating atmosphere-controlled muffle furnace, which is designed for material synthesis under a controlled inert gas atmosphere up to 1100 ºC with better temperature uniformity. The atmosphere furnace consists of high-quality alumina fiber brick and Kanthal Fe-Cr-Al heating elements.
HT1200-S Atmosphere Controlled Muffle Furnace is a five-side heating atmosphere-controlled muffle furnace, which is designed for material synthesis under a controlled inert gas atmosphere up to 1100 ºC with better temperature uniformity. The atmosphere furnace consists of high-quality alumina fiber brick and Kanthal Fe-Cr-Al heating elements with 64L capacity, as well as a vacuum-sealed steel case with a water cooling jacket. This atmosphere furnace is an ideal tool for preparing new materials which require a heat treatment under inert gas or oxidizing gas.
SPECIFICATIONS of Atmosphere Controlled Muffle Furnace:
- Furnace Structure
Double-layer stainless steel structure for maximum vacuum and safety,
The refractory alloy muffle is built-in with a water-cooling wall with dimension 470 LX 410W X 550H (mm), which can stand at positive pressure up to 0.06Mpa and vacuum up to - 0.09Mpa.
High purity porous alumina is built-in inside of the refractory alloy muffle as thermal insulation
Water cooling front door and air cooling shell of atmosphere furnace
Built-in Pressure gauge, vacuum valves, and two gas flowmeters.
The furnace be used with Inert gas or low vacuum ( 10-1 torr by the mechanical pump)
It also can be used with pure oxygen with the modified power connection. Please call us if you use oxygen.
Refractory ally box inside the heating chamber is optional for better inert gas control
- Chamber Interior
Five sides heating, e.g. left, right, bottom, back, and front, to achieve the best temperature uniformity than three sides heating of atmosphere furnace.
High-quality fibrous and porous alumina is used as the thermal insulation layers.
Kanthal 1350°C grade Fe-Cr-Al resistance heating wire
Heated chamber: 400x 400x 400 mm (~ 16"x16" x16"), 64 Liter
- Working Temperature & Constant Temperature Zone
Continuous Working Temperature 1100° C
Maximum Working Temperature 1200°C (< 1 hrs)
Constant temperature zone:
+/- 1°C within center 250 mm cubic zone
+/- 1.5°C within center 300 mm cubic zone
Maximum Sample Loading 35 kg
- Temperature Controller of Atmosphere Controlled Muffle Furnace
FA-YD518P-AG temperature controller is included.
Proportional–integral–derivative control (PID control) and auto-tune function

A 16L/min recirculating water chiller is included for cooling the furnace
Short water power off and Over-temperature alarm built-in
- Working Gases (optional) of Atmosphere Controlled Muffle Furnace
All types of inert gases such as N2 and Ar at《 0.03Mpa.
Pure oxygen gas <0.03Mpa. but need modifying internal connection wire for anti-oxidation, please call us in advance if you use O2 gas for atmosphere furnace
Low vacuum 10-1 torr due to fibrous alumina insulation material. Using 5% H2 + Ar will improve oxidation during heating. For oxygen-sensitive material, please use a hydrogen furnace.
- Power & Working Voltage
9.5 KW, 208 - 240V single phase, 50/60Hz
Three-phase, AC 380V - 460V available upon request.
Note： Power cable included but without a plug. Please install a plug by your own
- Warranty: One-year limited warranty with lifetime support
We reserve the right to upgrade the furnace structure for better performance without notice
- Warning & Note of Atmosphere Controlled Muffle Furnace
The Max pressure of this furnace is 7.5 PSI （ 0.5 atm ). You must install a pressure regulator on your gas tank to avoid over-pressure.
Corrosive gasses or materials that react with the FeCrAl alloy heating elements cannot be used in the furnace!
Toxic, corrosive, or flammable gasses are not recommended for use with this furnace. Please consult with our engineering team for more details
Please contact HT engineer whether your processes are compatible with this furnace. Graphite or carbon-based samples are not recommended to use.
