Flotation dryers are ideal for applications where the web is coated on both sides, or for delicate webs that cannot be mechanically supported. By directing heated air at the product from both sides, flotation dryers produce more effective heat transfer rates per running length of the dryer. The specially designed nozzles support the product on a bed of air, thus the term “flotation”. At Glenro, we apply our process experience to evaluate your performance criteria and the physical characteristics of the materials to be heated to form the basis of any system recommendation.
Nozzle Design Considerations:
- Low Tension vs. Airfoil
- Nozzle Gap
- Nozzle Opening
- Nozzle Centerline Spacing
- Nozzle Air Velocity
Dryer Design Considerations:
- Horizontal
- Integrated Designs
- Double Wall Insulated Steel Construction
- Prepackaged, Skid Mounted Heating Apparatus
- Clamshell Access, Screw Jack Access or Access Doors
- Product Threading, Motorized or Manual
- Constant or Variable Volume Control
- Process Temperature Control
- CE, CSA, CUL, FM, IRI, UL Approved Designs
Flotation dryers provide consistent and uniform drying results, and the nozzles’ design is critical for dryer performance. At Glenro, we carefully select the nozzle configuration that provides the most effective heating and exhaust for each application, while also keeping cost considerations in mind. We’ll fine-tune the variables of air volume, temperature, and velocity to ensure that you can make a better finished product, faster and less expensively. Our flotation dryers are designed to meet the highest quality and safety standards, and we offer a range of options to suit your specific requirements.
