All Metal Américas furnaces are produced with high quality refractory, which guarantees an excellent thermal efficiency and a longer working life for the equipment. The burners used in the Metal Américas furnaces are of the air-gas or oxy-gas (this one might also be on oil) type, with curves of independent work, to ensure a good stoichiometric balance, higher thermal efficiency and consequently, a lower metal oxidation and higher metallic yield.
