Air Flotation SystemsContinuous development of Spooner Air
Flotation Systems has established an unrivalled range of equipment
for all web processing industries.
Air Flotation DryersUtilising Air Flotation nozzles to transfer
heat to a moving web and support it on a cushion of air as it moves
through the dryer.
Self-Threading EquipmentSpecialised flotation nozzles to
automatically thread a web of any width, throughSpooner flotation
dryers and ancillary equipment without external assistance.
HPC DryerVery high evaporation rates in a compact form; suitable
for combination withIR dryers handling low and high tension paper
substrates.
Inert Atmosphere DryerUtilising a nitrogen atmosphere within the
dryer, for solvent based coatings, allows safe operation, low
operating cost, solvent recovery and low VOC emissions to
atmosphere.
Air Flotation CoolersNon-contact high performance cooling
equipment for films, paper and metal strip.
Jet FoilHigh performance dryer replacement for paper drying
cylinders allowing forshrinkage.
Low Tension DryersUse of specifically designed nozzles allows
flotation of webs with minimumtensions whilst ensuring high heat
transfer rates.
Curing OvensNon-contact double sided support allowing excellent
temperature control and consistent product performance.
