Oil-Heated Heat Treatment Furnaces are furnaces that use oil-based heating systems to control temperature. These furnaces are typically preferred for applications operating at low to medium temperature ranges. Oil serves as an efficient heat transfer medium, ensuring uniform heating of the material. Oil-based systems offer more precise temperature control during heat treatment, making them especially reliable for tempering, normalizing, or annealing processes of metals. Thanks to their durable and long-lasting construction, oil-heated heat treatment furnaces are widely used in various industrial applications.
