Advanced Canopy Hood With Side Draft
A Combined Side Draft Hood & Top Canopy Hood System is an advanced industrial fume extraction solution specifically developed for induction furnace applications where different process stages generate emissions in different directions and intensities.
The system combines the advantages of a Side Draft Hood during the melting process and a Top Canopy Hood during slag removal and metal tapping operations, ensuring maximum fume capture efficiency throughout the furnace operating cycle.
During the melting stage, most fumes and smoke are generated at the furnace mouth and tend to move horizontally due to furnace turbulence and shop-floor air disturbances. The Side Draft Hood is strategically positioned adjacent to the furnace to capture these emissions directly at the source before they disperse into the workplace.
Optimized Multi-Stage Fume Capture Technology: How do they work?
During slag removal and molten metal tapping operations, a significant quantity of hot fumes, smoke, and gases naturally rise upward. The Top Canopy Hood installed above the furnace effectively captures these emissions through thermal uplift and induced draft, ensuring comprehensive fume collection during these critical operations.
The collected contaminants are conveyed through a ducting network to a dust collector, bag filter, wet scrubber, or other air pollution control equipment where particulate matter and harmful pollutants are removed before clean air is safely discharged into the atmosphere.
Reliable Industrial Fume Extraction Solutions
INDOFAN Combined Side Draft Hood & Top Canopy Hood Systems are specially engineered for induction furnaces, foundries, and metal melting industries requiring high-performance fume extraction throughout the entire production cycle.
By utilizing two dedicated hood arrangements for different operating conditions, the system provides significantly improved fume capture efficiency compared to conventional single-hood extraction systems. This integrated approach minimizes fugitive emissions and enhances workplace air quality.
