Rotary Hearth Furnaces

The Gadda group produces high quality rotary hearth furnaces, which can be integrated in a complete line and automatically fed by robot arms allowing parts tracking. Rotary hearth furnaces are extremely versatile and their high throughput and repeatability of results make them particularly suitable to treat large quantities of similar or identical parts. Optimal sealing of the rotary chamber is obtained with a liquid channel sealing system. A rotary furnace can be designed to lay directly on the floor without the need of a foundation. Furnace loading can be programmed on multiple circular layers in order to fill the chamber with small parts. In rotary furnaces with double doors, a vertical wall in between the two doors reduces thermal losses during loading/unloading operations.
