Abstract
An air spray painting apparatus for sending a fan of atomized paint spray via a first entrainment flow of carrier fluid and of a second flow of carrier fluid, separate from the first entrainment flow and capable of forming the spray fan, includes electrical heating elements for heating to one and the same temperature the first and second flows of carrier fluid, and a unit for regulation and control of the heating elements.
Claims18
An apparatus for air spray painting of a substrate, the apparatus comprising:
- at least one spray dispenser configured to send a spray fan of liquid atomized paint, the dispenser being provided with at least one first nozzle and at least one second nozzle supplied by respective separate ducts to issue, respectively, a first flow of carrier fluid to entrain the paint and a second flow of carrier fluid, separate from said first entrainment flow, to confine the spray fan externally, said first and second flows being supplied at pressures regulated independently;
- a temperature conditioning system set upstream in the proximity of the dispenser, the temperature conditioning system being configured to condition the temperature of said first and second flows of carrier fluid to the same temperature;
- and
- a temperature regulation and control system configured to regulate and control the temperature induced in the flows of carrier fluid by said temperature conditioning system.
An integrated system for thermal conditioning and ionization of a carrier fluid for electrostatic air spray painting provided with inlets and outlets for a first flow and a second flow of a carrier fluid, the integrated system comprising:
- a temperature conditioning system configured to condition the temperature of a first flow of carrier fluid and a second, separate, flow of carrier fluid to the same temperature;
- and
- first and second independent ionization systems configured to electrostatically charge the first and second flows of carrier fluid with negative, or positive, or neutral-state ions,
- wherein said temperature conditioning system and said ionization systems are connected via connections to a temperature regulation and control system configured to regulate and control said temperature and said ionization charges.
