Typical schematic of a Roller Support Impingement Oven
Spooner offers a wide range
of control options including:
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.
