Harper International Corporation Hearth Load Carrier Furnaces

A major innovation in graphite systems technology, the heart of this patented new system is the Harper Hearth Load Carrier. It reduces load thermal mass, improves temperature uniformity and redistributes compressive stress and wear surfaces away from potentially corrosive/erosive environments. The Graphite Harper Hearth has energy recuperation and single point access that significantly improve process economics over existing ultra-high temperature pusher and other furnace technologies. Applications include gas-solid and solid-solid chemical reactions and pressure-less sintering at temperatures up to 3000ºC.
