Vacuum Furnaces

What is a vacuum furnace?

Hobersal vacuum furnaces are furnaces for vacuum heat treatment.
The absence of air inside the chamber avoids oxidation during the process and guarantees the best results.

Which applications are most used in a vacuum furnace?

Vacuum furnaces are used in a wide range of applications in both production industries and research laboratories.
Vacuum furnaces are used to carry out processes such annealing, ceramic and metal sintering, brazing and heat treatment consistency and low contamination in a defined, mostly non-oxidising, atmosphere.

Types of atmospheres possible in a vacuum furnace

Vacuum is already an atmosphere and can be 1Mbar, x10-2Mbar and x10-5Mbar. Additionally, as a vacuum furnace allows complete removal of the air atmosphere, it is also possible to work with various gases or mixtures, such as Nitrogen, Argon, Helium, Formigas, Hydrogen, Carbon Monoxide…

Why should we choose Hobersal vacuum furnaces?

In addition to a vacuum furnace, Hobersal vacuum furnaces allow to work in controlled atmosphere and vacuum in the same process / program, how?
Hobersal vacuum furnaces with the EV-7 system allow to work in vacuum and controlled atmospheres in the same process.
A set of vacuum solenoid valves and a program designed with Eurotherm allows us to activate / stop vacuum, introduce / stop gases and aeration of the chamber.
It also allows vacuum at high temperatures thanks to our chamber design.
