The National brand of reinforced and perforated '''Suction Drum Dryers''' have some of the highest evaporation rates in the industry and have set a new standard in efficient thermal bonding, heat setting and drying of all types of non wovens and fibers. | The National brand of reinforced and perforated '''Suction Drum Dryers''' have some of the highest evaporation rates in the industry and have set a new standard in efficient thermal bonding, heat setting and drying of all types of non wovens and fibers. | ||
Multiple drum dryers are ideal for applications requiring high line speed, extended dwell time and in-line temperature profiling for heat setting, thermal bonding or cooling. | Multiple drum dryers are ideal for applications requiring high line speed, extended dwell time and in-line temperature profiling for heat setting, thermal bonding or cooling. Drums are either standard perforation for a wide variety of applications or are reinforced structurally for high vacuum, high speed applications. | ||
