  • Door open/close limit switch installed as standard equipment
  • The programmer is a 19-pattern, high-performance type.
[Note]
The furnace is shipped with the heater removed to prevent damaging during transport. Before assemble the received furnace, check for damages.
Applications Electronic component firing , Ceramice firing, Insulating material sintering process
Option Supply port, Exhaust port, Temperature Recorder, Gas supply system

The furnaces are structured to use 2-shank, 90-degree bent molybdenum disilicide (MoSiO2) heaters to achieve long lives and reduce heat loss. The heater can be easily replaced from the furnace inside by removing the cover and clip from the furnace outside. The furnaces are designed to install door open/close limit switches as standard equipment, for securing safety, and use 19-pattern, high-performance programmers. Alumina fiber based hearth plates are used to secure high reliability and durability even if heat treatments are held at as high temperature as 1800°C.
