aluminum crucible furnace
Spiral Furnace with SPW Burner
Comparison with conventional furnace
Spiral furnaces are designed to optimally circulate heat according to the crucible used by the customer, taking into consideration the space inside the furnace and the pressure inside the furnace.
Furthermore, by providing a flow path to circulate exhaust heat, we succeeded in maximizing the heat exchange function of the burner.
In addition, the exhaust heat path is provided inside the furnace to reduce heat dissipation, further enhancing the energy-saving effect.
