Impingement dryer designs are common for many web and fabric drying applications. Unfortunately, many of these applications are handicapped by less effective nozzle designs. Glenro offers the process experience, engineering capabilities and testing facilities to maximize the drying performance of this type of hot air system solution for your application.
Nozzle Design Considerations:
Nozzle Gap
Nozzle Opening
Nozzle Centerline Spacing

CE, CSA, CUL, FM, IRI, UL Approved Designs

Tapered Nozzle Design
Glenro’s tapered impingement nozzle design provides excellent directional airflow. Gap, opening and centerline spacing are all application specific.

Return Tube Nozzle Design
Incorporates a tapered nozzle design with return air tubes between the center line spacing of the nozzles. This design is particularly effective for wide product applications.

Mailbox Nozzle Design
This diagram shows “mailbox” impingement nozzles, which generate a specialized airflow pattern.
