Product Details
Product Description
Product Overview:

An atmosphere furnace provides the ideal environment for various procedures in many laboratories, providing the controlled temperature and atmosphere specific projects require. The controlled atmosphere is desired to complete tasks that require exact temperatures pricisely. This is the best way to ensure the successful test result of your project because it is sealed tightly to ensure the right environment.

STQ 1200 series controlled atmosphere furnaces feature a chamber with Mitsubishi (Japan) high quality alumina fiber insulation and the top quality heating elements. A double walled steel internal housing helps minimize heat loss to exterior surface, also keep the surface safe to touch. Furnace operation is controlled by Shimaden (Japan) 32-segment digital controller with temperature accuracy of +/- 1 C degree. Proper temperature control is vital to the success of your project as well. Temperatures that are too high or too low will cause problems with the process and could cost your company a significant amount of money. SAFTherm furnaces come with built-in 32-segment PID digital temperature controller for accurate monitoring and consistency.

Usage Atmosphere furnace is designed for material synthesis under controlled inert gas atmosphere or mixture gases with better temperature uniformity. It is an ideal heating equipment for preparing new material which requires inert gas or oxidizing gas including hydrogen gas.
Furnace structure

1. The furnace is consist of heating system, gas system, vacuum system

2. chamber is consist of insulation material and heating elements and atmosphere boxes

3. Temperature controller is consist of PID temp. controller, control elements and thermocouple

4. Integrated the furnace body and the temperature controller in one, the furnace is fixed on the temperature controller

Max. temperature 1200℃ (in air)
Continuous Working temperature 1100℃ (N2)
Heating Rate ≤15℃/min (suggest 10℃/min for longer life using of furnace)
Heating Element Top brand iron-aluminum alloy resistance coil wire (HRE)
The wire elements are coiled and embedded in three sides of the wall (Elements located in ceiling, left and right sides)
Chamber material 1. Adopt high quality alumina polycrystalline fiber, which used Japanese technology (vac-sorb forming alumina polycrystalline fiber) with good insulation and durability properties
2. High quality 1300 degree fiber alumina as refractory lining, pure white color
3. Ceramic fiber insulation for fast heat-up and reduced energy consumption—rise time to 1100°>C takes only 50 minutes
4. Embedded heating elements on the round chamber which give an ideal temperature uniformity
Temp. Uniformity ±5°C
Thermocouple N type
Temperature Controller 1. Control system integrated in the furnace base, Defined application within the constraints of the operating instructions
2. Furnace temperature controller utilizes Intelligent PID 4 group 8 segments program
3. Feature single setpoint digital control, LED display of actual temperature VS set point
4. A high-precision digital microprocessor controller fitted with self-tuning and manual PID settings makes temperature and other parameters easy to control
5. Temperature controller Precision ±1℃
Atmosphere perfermance

high temperature PTFE gasket is installed on the furnace door to ensure the reliable sealing of the furnace;

Ultimate vacuum level for STQ furnaces is around 20000Pa with hose barb connections. Please keep in mind that our STQ series of atmosphere furnaces are NOT designed to be vacuum furnaces, the vacuuming part is mainly for users to pre-vacuum the chamber, before putting in inert or other protective gases.

inlet port and outlet

1.The inlet and outlet ports are designed on the side and back wall of the furnace body and can be supplied with inert protective gas. The gas flow rate is controlled by a float flowmeter with a range of 1-10L/min.

Electronic component SCHNEIDER maker air switch, buttons, solid-state relay, A.C contactor etc.
Furnace Shell 1. High quality cold-rolled steel sheets CNC processing
2. Environmental electrostatic plastic-spraying on surface after deoiling, derusting, phosphating etc. nine processes
3. Energy efficient insulation keeps exterior safe to touch
Safety Precautions 1. Overheating & Broken thermocouple protection
2. Leakage circuit breaker
3. Automatic power off when furnace door opens (optional function)
4. Over-temperature protection and alarm allow for operation without attendant(s)
5. Microprocessor-based PID control with self-tuning capability to prevent overshooting of set temperature
