Pusher Furnaces

Thermal Treatment System for High Volumes

AFC-Holcroft is the acknowledged leader in pusher furnace technology. Every AFC-Holcroft pusher furnace incorporates many unique and innovative features that were not only pioneered by AFC-Holcroft, but are found exclusively on AFC-Holcroft equipment. Our pusher furnace designs are often imitated but never duplicated.
