Vacuum Furnaces

Used in many different industries, vacuum furnaces are designed to heat samples in the absence of any gasses that might interact with them. These kinds of furnaces are capable of performing most heat treatment processes performed in standard furnaces, such as annealing, brazing, sintering, and tempering. All vacuum furnaces have a vacuum vessel, pumping system, heating chamber and cooling system. The features required for a vacuum furnace to run a particular heat treatment sequence are often based on the desired results, the type and shape of items to be processed, the productivity needs, the size of the load to be processed, the pressure and temperature to be reached, and the cooling method used, gas- or oil-based.
