The 1400°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.

These furnaces are ideally suited to produce precise temperature profiles otherwise achieved only in continuous type furnaces. Because of the low thermal mass fiber insulation and the high efficiency of the power control system, very rapid heating rates are also achievable.

Load Dimensions: Dimensions are listed in order of width, height and depth. Usable load dimensions refer to the actual volume available for setting of material or product for firing. Special sizes of the FastHeat furnace may also be available upon request.
Furnace Model Usable Load Size Load Volume Shipping Weight (approx.).
KSK-12 1400°C  12 x 12 x 12-inch 1 cu. ft. 420 lb.
KSK-15 1400°C  15 x 15 x 15-inch 2 cu. ft. 600 lb.

Furnace lining features a high purity, lightweight, 1400°C minimum rated alumina fiberboard construction designed for maximum energy efficiency and thermal performance. This lining is scored on the hot face in a tile design allowing it to expand and contract during thermal cycling. This provides a very durable construction that will last longer and need less maintenance.
