A Pit Furnace is normally used for processing batches or large single components. It is sunk into a pit, and has a lid/plug section which is lifted off and either placed else where, or is connected to a lifting arm that swings it to one side. The size and shape of the furnace will largely depend on the quantity and type off component that is being treated.
Pit furnaces either has exposed elements, or has an internal retort that is used for controlling the atmosphere needed for the treatment required. Most have a fan for circulation that can be fitted in the lid or in the floor (fitting in the lid makes for easier maintenance).
Pit Furnaces have a large scope for possible processes, commonly involving controlled atmospheres, i.e. Endo Gas, Ammonia, Hydrogen, Nitrogen, Etc. Prestige Thermal systems offer quick ramp-up and highest heating uniformity: temperatures are maintained to within 5 degrees throughout the retort. The result is high and uniform hardness on heavy sections, and protection from distortion and cracking, even on thin sections.
Prestige Thermal furnaces are heated by electricity or gas, and meet all international requirements.
Prestige Thermal systems are available in several equipment formats. Stages can be included to accommodate pre- and post-treatments. Material handling interfaces are custom-designed to individual requirements.
