Pit Type Furnaces

IVA- Pit type furnaces, series T...e/g(V) are available with and without metallic retort, depending upon temperature and process to be performed. These furnaces with operating temperatures of up to 1.000 °C are mainly used for the following processes:

• (Gas) Carburizing

• Carbonitriding

• Annealing processes under protective atmosphere as well as air

• Nitriding

• Nitrocarburizing

It is worthwhile to note, that this type of furnace has seen a renaissance over the past decade for the application deep case gas carburizing of large gear components for gearboxes of windmills. IVA has remarkably participated in that boom by providing large installations into this industry in Europe and Asia.

The same advanced technical features apply as with all other heat treatment equipment, available from IVA such as:

• Energy efficient design w/ ultra light weight fiber insulation

• Fast response heat-up and cool-down if necessary for the process

• Add on systems as per demand such as high efficient cooling systems

• Energy efficient heating systems w/ high efficient recuperated gas burners

• Excellent temperature uniformity

Auxiliary equipment for complete equipment set-up include:

• Advanced atmosphere panels

• Variable atmosphere flow system where flow quantities can automatically and economically be adopted to the process needs

• Evacuation systems

• IVA’s unique nitriding package including post treatment options

• Air circulation tempering furnaces

• Oil quench

• Salt quench

• Polymer Quench

• Washers

• Atmosphere generators
