Abstract
A spray nozzle system includes separate air outlets to deliver one or more streams of supplemental warming or drying air. The air may be applied while spray is emitted from the nozzle to increase the spray cloud temperature, or may be applied for warming or drying before or after the spray application, with the spray turned off. In the case of air-atomizing nozzles, the air is delivered through low pressure ports separately from the atomizing or pattern shaping air to minimize the expansion cooling effect. In another implementation, the air is redirected from the nozzle using a control valve which proportions the amount of airflow directed for atomization, pattern shaping and drying.
