Vacuum Tempering Furnace by Therelek

As is the case, the toughness of an alloy is known by its capacity for elastic deformation and energy absorption before the material fractures; it calls for a really advanced technology to give the high quality treatments that are required by various alloys these days for a wide range of engineering purposes.


This is where Therelek hits the exact chord. A Therelek Vacuum Tempering Furnace is known to be a typically sturdy industrial oven designed to heat treat any form of ferrous metal product and also increase its toughness.

One would typically have three categories of vacuum tempering furnaces, as offered by Therelek. Let’s have a look at them:

Vertical/Bottom Loading Vacuum Furnace

Therelek’s convenient vertical vacuum furnace takes up only a small area and hence saves much space for the plant. If this wasn’t enough, one may have a temporary storage for the load under a vertical vacuum heat treatment furnace and later on ascend as per convenience. These furnaces carry out temperature measurements even in hard-to-reach areas. Due to great configuration, one may trace thermocouple sensors anywhere in the whole furnace.

Front Loading/ Horizontal Furnace

Therelek’s Horizontal Vacuum Furnace is known to have a sturdy cold wall as a structure with a metallic or graphite hot zone. Having sliding doors, the material is loaded from the front of the horizontal heat furnace that in an overall manner, ensures excellent uniformity throughout the chamber. A number of high end technology driven engineering industries like aerospace, auto, defence, atomic, etc. are in need of the Horizontal Gas Quench vacuum furnace, in order to carry out their various vacuum heat treatment.

Bell Jar Furnace

The Bell furnace by Therelek is specially designed to offer optimal performance for high sensitivity and delicate components. Very conveniently, the furnace chamber is cylindrical in shape and the assembly is double-walled so as to attain a very high-quality surface finish for the material.
