Air Flotation
Spooner has designed and built ‘State of the Art’ Flotation Systems for more than 30 years. Constant development of special air bar systems provides unique solutions to continuous strip processing requirements.
The Spooner family of air bars includes a range of nozzles with specific advantages for the metals industry, offering operating distances of 10 to 200mm.
Spooner Air Flotation nozzles offer:
Non-Contact Web Handling: The strip is supported throughout on a dynamic air pressure pad with high clearance. This makes the system effective for a wide range of processes and substrates.
Superior Strip Stability: Ensuring constant flotation performance.
Maximum Performance: High heating and cooling rates.
Energy Saving: Minimal energy consumption.
Wide Operating Tension Range: Providing optimum operating flexibility.
Sine Wave Flotation: Reduces strip crossbow.
Wide Width Capacity: Nozzle widths over 9m.
Robust Construction: Offers consistent performance.
Even Pressure Distribution: Gentle on coatings.
Air Impingement Technology
Spooner offer a full range of high efficiency non-flotation impingement nozzle systems for all areas of the Metals Industry incorporated into catenary, vertical and roller support ovens. Typical Spooner nozzle designs include:
Hole based designs giving high heat transfer rates, consistent performance and low maintenance.
Precision slots, which give even heat transfer across the strip width and are gentle on sensitive coatings.
Laminar flow nozzles, which blow air at 90° to the strip to give effective drying whilst protecting very
sensitive coatings.
Combination nozzles which can be converted from slots to laminar flow designs automatically to give
maximum flexibility for a range of coatings.
