Vacuum pit-type furnace for carburizing large case depths of massive and longitudinal parts
Low Pressure Carburizing (LPC) vacuum pit type furnaces.
The SECO/WARWICK Pit-LPC is a high-efficiency vacuum pit furnace engineered for carburizing massive and longitudinal parts requiring large case depths. This state-of-the-art system delivers a 3-to-1 efficiency ratio, allowing you to replace three conventional atmosphere furnaces with a single Pit-LPC unit. By transitioning to high-temperature vacuum processing, manufacturers significantly increase production capacity while drastically reducing floor space, energy costs, and environmental impact.
Key Advantages & Operational Savings
-
Footprint & Capacity Optimization – one Pit-LPC furnace delivers the output of three traditional atmosphere furnaces, maximizing your shop floor productivity.
-
Cost & Energy Reduction – shorter process times achieved through higher operating temperatures directly translate to lower utility and maintenance costs.
-
Maximum Workplace Safety – operates entirely in a vacuum, eliminating flammable and explosive atmospheres and meeting the most stringent ecological standards.
-
Uncompromising Quality – high homogeneity of process parameters ensures precise carbonized layer thickness and superior metallurgical quality for heavy-duty components.
