Pit-LPC™ – Vacuum Carburizing Pit Furnace for Deep Case Depth on Large Parts

Pit LPC is a state-of-the-art pit-type furnace solution meeting the most stringent environmental standards, while increasing worker safety through elimination of flammable and explosive atmospheres. High homogeneity of process parameters has a direct effect on the thickness of the carbonized layer and, as a result, on the quality of the processed workpieces. Plus, the unit can be reconfigured to the client’s needs; SECO/VACUUM will adapt the Pit LPC furnace so that it can be installed in the old atmosphere furnace bay.

This LPC vacuum furnace is perfect for manufacturers carburizing large or long elements such as gears, bearings, drilling tools and other elements requiring thick case depths and it is a great furnace for companies who want to increase their production capacity without purchasing additional equipment (1 Pit LPC = 3 atmosphere furnaces), or save space by replacing three machines with one that fits into the same space as one.

• Create the highest quality and uniformity in the process
  The Pit LPC provides carburizing on large elements such as some larger gears, bearing races, large cutting tools and other elements requiring thick carburized layers, while providing high homogeneity of the process which has a direct quality effect on a thick carburized layer. For all workpieces, large or small, there is no intergranular oxidation (IGO) effect which provides a better appearance after processing, a quality that can enhance sales.
• Reduce your production and capital costs
  Another benefit is that there is minimum consumption of process gases providing reduced costs compared to standard atmosphere processing. Also, there is often less capital equipment expense: one Pit LPC equals three atmosphere furnaces so there is less floorspace needed and often lower capital cost.
• Save time and increase productivity
  Atmosphere furnaces require purging and atmosphere conditioning prior to start up which can slow down production. The Pit LPC provides low-pressure carburizing on an instant on-and-off basis providing better flexibility as well. Additionally, this vacuum carburizing furnace works with a quicker high-temperature process than atmosphere carburizing furnaces.
• Increase work safety
  Eliminate the flammable and potentially explosive gases of an atmosphere carburizing furnace since the Pit LPC uses no combustion.
• Friendly to the Environment and the workforce
  The Pit LPC is a cleaner process providing low-heat emission and no pollution of combustion products (CO or CO2)
