Thermal Profiling Solutions for Vacuum Annealing

In the majority of applications, the choice of thermal barrier is determined by the ambient factors and process parameters in the furnace, such as temperature, time, and atmosphere. The choice of a thermal barrier is more important than numerous data logger configurations and software options, which are both accessible.

Thermal barriers from the TBB-250 are designed for infrequent and less demanding profiling applications and have a maximum operating temperature of 950°C. They stand for our most cost-effective option.

The Horizontal Vacuum Annealing Furnace is designed to heat treat reactive metal tubes and bars and their alloys under vacuum. The vertical annealing vacuum furnace is mostly used for lengthy components, such as overweight rod shaft parts, that need to undergo vacuum heat treatment, recrystallization of non-ferrous metals, or annealing ageing treatment. It is a hot, side-loading, cylindrical wall furnace with a task temperature consistency that is positioned horizontally. The furnace has three chambers: a central hot chamber, cooling chambers on either side, and a loading station and platforms with pulling/pushing mechanisms on either side.

To fill this need, Tempsens offers a range of temperature profiling solutions designed specifically for use in the steel/metal heat treatment processes.


  • Oven surveying for batch and conveyorized
  • Tempering and precipitation hardening of steel and aluminium
  • Mesh belt for reducing stress on parts and raw materials
  • Component and raw material annealing and hardening on mesh belts
  • Process measurement for conveyorized and batch carburizing
  • Oven surveying for batch and conveyorized

The TBB-250 thermal barriers box is more resistant to distortion and corrosion thanks to our floating plate design and unusual material choice because case depth and hardness depend on precise atmosphere and component surface temperature control.
