Chamber Muffle Furnace >>

The Overview of Chamber Muffle Furnace
WINTHERM chamber muffle furnace range has a maximum operating temperature of 1800°C and chamber capacities up to more than 2000 liters. It is mainly used in the Universities.Colleges ,Laboratories, Institutions of higher learning, Scientific research institutions.Factory enterprises and apply to new material fields such as metal material, ceramic material, nano material.semiconductor material applications etc.
  • Chamber furnaces generally has a much larger working chamber size and suitable for different size and type of samples for heating.
  • For special usage of experiment process, it is better to consider fully to check the function or whether need to choose other type of furnace.
  • When choosing a furnace, also need to consider whether the special parts for samples. Like powders in crucibles and other tools.

How to choose a Muffle Furnace ?

What is the operate temperature?
  • WINTHERM muffle furnace mainly with range of 1200°C, 1400°C, 1700°C and OEM 1800°C.
  • When real operating lower than 1200°C, we generally use high grade HRE spiral wire coils as heating element.
  • When real operating lower than 1400°C, we generally use high grade SIC ( Silicon Carbide Heaters ) heating element.
  • When real operating lower than 1700°C, we generally use high grade MoSi2 ( Molybdenum Disilicide Heaters ) heating element.
  • Continuous operating temp will be 100°C below the max temp design and right using will extend the furnace service life.
  • Furnaces are designed to operate at high temperatures. Operation below temperatures of approximately 600 °C will be less accurate and continuous use at low temperatures may reduce the element life of some furnaces, ie MoSi2 heated furnaces.
What is the chamber size required?
  • WINTHERM definite and real working chamber size with Width ( W ) , Depth (D) and Height (H) and you will see the specification with W*D*H (mm).
  • WINTHERM has wide range of working chamber size for chamber furnaces.
What is the temp controller?
  • WINTHERM standard furnaces controlled by SHIMADEN (Japan ) 32 segments digital PIO (proportional, integral and derivative) controller with accurate control.
  • Multi-segments and/or multi-program controllers are available as an option on most models or any other brand models as customer want to have.
  • The Furnace built-in RS485 digital communications port and USB adaptor as optional setting , allowing the user to connect to a PC for remote control and monitoring of the furnace. You can also save or export test results.
What is electric parts used?
  • WINTHERM furnace all use international parts to keep safety and quality.
  • Main Electric parts use France SCHNEIDER electronics parts.
  • Main Control use USA Crydom Solid Relay or German SEMIKRON SCR control.
What is your OEM furnace service?
  • WINTHERM has professional designers team and can design different furnaces according to customer technical request.
  • WINTHERM will confirm the OEM design with customers before final manufacturing.
