Suction Drum Dryers for Nonwovens
Efficient through-air drying (TAD), thermal bonding, drying, curing, finishing and cooling of nonwoven products.
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 nonwovens 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. Single drum Omega design dryers feature high evaporation rates for short dwell time, high speed, delicate web or single sided contact applications. Drums are either standard perforation for a wide variety of applications or are reinforced structurally for high vacuum, high speed applications.
Applications: Through-air drying (TAD), thermal bonding, heat setting, curing, finishing of nonwovens such as spunlaced (hydroentangled), air laid, wet laid, spun bond (SMS composites), coated and foam impregnated webs.
Robust design using heavy gauge materials for long operating life
Single drum and multiple drum configurations available to match the process requirements
Construction materials to suit product
Flat bed through-air dryers (TAD)are also available for high loft and loose web nonwoven applications that require gentle through-flow processing and support throughout the heating process.
