The 1800°C Box Furnaces (FastHeat) by Keith Company have proven to be extremely versatile and dependable for research and development, small-scale production, and any application requiring special and complex temperature profiles. We manufacture this furnace as a box style furnace with up to 16.8kW or bottom loading furnace with up to 18kW of power with MolyD heating elements.

These industrial furnaces are ideally suited to produce precise temperature profiles otherwise achieved only in continuous type box furnaces. Because of the low thermal mass fiber insulation and the high efficiency of the power control system, heat up cycle to highest temperature can be less than 45 minutes. With active cooling like air or Nitrogen the furnace can be cooled down in less than one hour.

An optional thermal oxidizer for the abatement of Volatile Organic Compounds (VOC) during the burnout cycle of ceramics can be installed.
