Traditionally for many decades and even today, international bell furnace manufacturers deploy continuous purging of cracked ammonia, throughout the annealing cycle, to avoid decarburisation. This being an expensive process, involving not only consumable costs like ammonia, cracker catalysts etc, but also this involves a good amount of instrumentation associated with the system including expensive maintenance.


Precons, by its innovative technology, has successfully developed cracked hydro carbon gas purging system, only for a few hours as against continuous purging of cracked ammonia, thus cutting down enormous expenditure in each cycle and practically nil maintenance achieving almost nil decarburisation, after annealing.


Each bell furnace installation comes with state of the art temperature and Thyristor control systems and user friendly PLC and Scada display panels. We bring forth an excellent collection of Bell Furnace. Our given bell furnace is manufactured from the top notch factor inputs and cutting edge technology in order to meet the international quality standards. Our offered bell furnace is accessible in numerous specifications as per the variegated needs of customers. As well, our valuable customers can avail this bell furnace from us at industry leading rates in a given time frame.

Electrically heated salt bath furnaces for uniform and fast heat treatment of work pieces and tools under exclusion of air.

  • Custom-built for customers’ applications and requirements.
  • Proven and reliable in rough production use due to strong and robust construction.
  • Low energy consumption, low operation costs due to high-quality thermal insulation.
  • Heating elements wound on ceramic tubes; Uniform heating of salt bath.

A Salt Bath is a largely overlooked alternative to many types of furnace. It has many advantages and a few disadvantages over conventional atmosphere furnace.

The heating medium of a salt bath is the salt itself. This is heated to the required temperature by either external heating, over the side submerged elements, or submerged electrodes. When a load is submerged into the salt it is heated rapidly and uniformly to the required temperature. The salt also doubles as a protective atmosphere during the heating cycle. When the load is withdrawn a thin covering film of salt will protect it.

Temperatures available can range from around 1500c to 13000c. The low temperature ranges can be heated by external heating to a salt pot, or over the side submerged sheathed wire elements. Above 6000c, over the side submerge elements suffer severely from corrosion at the salt-air interface (where the elements/electrode enter the salt). At these temperatures and above we recommend totally submerged electrodes, which enter the bath through the side-wall (below the salt-air interface) and apply heat by using the salt itself as the resistance element. This method has many advantages over any heating method that enters the bath over the side wall. Not only does it eliminate the electrode corrosion at the salt-air interface, but also reduces the top losses (heat escaping from the top of the bath) because the bath can be smaller. It also aids salt circulation and agitation due to electro-dynamic forces.

Some processes will require other equipment to complement the Salt Bath.
