Box Furnace KBF 1250°C Series

Maximum temperature
1250°C

Feature

  • Our unique Moldatherm LGO heaters (*1) are used.
  • Programmers are installed for temperature control as standard equipment.
  • SiC based hearth plates
  • Optional muffles (*2)(metallic vessels) can be used for firing in sealed inert gas atmospheres.
  • Door open/close limit switch installed as standard equipment
*1: Moldatherm heater: Heater equipped with thermal insulator. Our original heater is made by integrating ceramic fiber and a wavy heating element (LGO) into a solid structure using our unique vacuum forming method. Moldatherm heaters are also used for the heaters made by our company for the production use semiconductor devices and metal heat treatment systems.
*2: With a muffle, the maximum working temperature will be 1000°C.
Applications R&D, Firing
Option Supply port, Exhaust port, Temperature Recorder, Muffle, Gas supply system

The compact, energy-saving, experimental, electrical furnaces (box furnaces) are high-performance types that are equipped with muffles enabling heat treatments at 1250°C. Highly heat-resistant SiC based hearth plates are used and all models are installed with temperature control programmers and door open/close limit switches as standard equipment. Four furnace sizes are available. Simple gas introduction units are optionally available, for easy introduction of inert gases, air and other gases.
