Feature:
The unique structure of heater installation on the furnace back reduces shell loss and makes maintenance easier.
Door open/close limit switch installed as standard equipment
The furnaces are desktop type but can perform heat treatments at up to 1500°C, and auto-mode experiments are available using programmers.
Thanks to the high-performance thermal insulating materials and compact design, a high-response, superior temperature rising characteristic has been achieved.
