High Temperature Furnace - HTF
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
Standard Features
- Advance refractory interior, used in combination with energy-efficient low thermal mass insulation.
- Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
- Equipped with thermocouple break protection that helps to prevent thermocouple failure run away
- An exhaust air outlet at the rear wall of the furnace
- Power control through Solid state relay or Thyristor unit provides low noise operation.
