High-temperature steam industrial drying ovens (also referred to as superheated steam drying ovens) use saturated or superheated steam as the primary heat transfer medium instead of hot air. They typically operate from 150 °C up to 350 °C (and higher in special designs) and are applied where oxygen-free drying, high energy efficiency, or product quality preservation is required.
