Electrostatic spray nozzle including induction ring

An electrostatic spray system including:

• an electrostatic spray nozzle assembly comprising:
• an induction ring;
• and
• a fluid tip,
• wherein the induction ring generates an electrical field for inducing an electrical charge on droplets of a feedstock liquid from the fluid tip that pass through an opening of the induction ring,
• wherein the induction ring is electrically coupled to an electrical induction field source via a first electrically conductive path provided by electrically conductive surfaces of:
• a nozzle head holding the induction ring, and
• a purge gas tube holding the nozzle head;
• wherein feedstock flowing through the fluid tip is electrically coupled to a charge carrier source via a second electrically conductive path provided by electrically conductive surfaces of:
• the fluid tip;
• and
• a fluid tube electrically coupled to the fluid tip;
• and
• wherein the first electrically conductive path and the second electrically conductive path are electrically isolated by an insulating barrier;
• and
• a voltage supply for providing an electrical potential to the induction ring via the first conductive path.
