Pyradia offers an extensive range of high-efficiency single sided or dual-sided roll support dryers. Roll support dryers are widely used in the converting industry and available in various configurations, such as arched, flat or horseshoe, whether you are drying papers, films, nonwovens, or textiles substrates. Ultra low web tension can be achieved with tendency driven rollers or air bearings. Rollers can also be driven at line speed, with either servo ratio control or web tension feedback.
Ideal for single sided coated applications, these dryers can be equipped with various nozzle shapes, for optimizing the drying process efficiency, while preventing coating defects. High-velocity impingement creates turbulent airflow at the surface of the coating, efficiently removing moisture, by breaking the humidity barrier to attain elevated evaporation rates. This approach ensures thorough drying across the entire surface of the material, eliminating localized high moisture content and preventing over-drying or overheating. Dual sided dryers are equipped with nozzles on top and bottom sides of the web, allowing for quicker heating of the substrate while controlling the drying rate.
Pyradia impingement roll support dryers can accommodate web width from 12in to 120in wide, or more, with temperature range up to 450°F, and have no limitation on length.
With over 50 years of experience, extensive process knowledge, drying modeling software and pilot drying equipment, Pyradia engineers will analyse your specifications and recommend the ideal dryer configuration for optimal process efficiency.
