High Temperature Furnace - HTF

High-temperature furnaces are another type of laboratory furnace capable of reaching higher temperatures between 1400°C up to 1800°C. A high temp furnace typically consists of heating elements located on both sides of the heating chamber to ensure good thermal uniformity. Process applications for a high-temperature furnace include sintering of high-temperature materials, glass melting, and high-temperature testing of ceramics, fusion and firing processes, and powder metallurgy processes.

High-temperature furnaces are insulated with fibre material. Furnaces with fibre insulation achieve significantly shorter heating up times because of the low thermal mass.

Tempsens is ISO and CE certified Laboratory & Industrial furnace manufacturers and suppliers. Tempsens provide range general purpose High-Temperature Furnace in three temperature ranges i.e. 1400°C, 1600°C & 1800°C
