Pit furnaces like these are used in general engineering and metallurgical applications for carburizing, nitriding, carbonitriding, nitrocarburizing, hardening, tempering, annealing and also in process industries like coal tar processing, separation of titanium and magnesium from ore etc.

Special processes such as aluminium and titanium heat treatment can also be done. In process industries, these furnaces can also be used in high-pressure applications with temperatures from 800°C to 1200°C and pressure ranging from 400mm water column to 9 bar. These are often laid in a pit to make most of the space available and charges can be loaded and unloaded easily.

These are manufactured considering working controlled atmospheres with inlets for diffusion and distribution of cracked ammonia, hydrogen, LPG, methanol, argon, nitrogen and other process fluids.

Therelek manufactures and sets up complete automated process plants also. Temperature control, fluid dissociation, gas penetration and dosing can all be taken up for automated operation.
