<p>A system, in certain embodiments, includes a spray device including a frame having a receptacle configured to receive a self-contained spray can. The spray device further includes a first conductive element configured to contact the selfcontained spray can, and a first electrical conductor extending between the first conductive element and an earth ground such that a first electrical potential of the self-contained spray can is substantially equal to a second electrical potential of the earth ground while the self-contained spray can is in contact with the first conductive element. The spray device also includes a corona-charging electrode positioned adjacent to a spray nozzle of the self-contained spray can. The corona-charging electrode is configured to emit a stream of ions toward the self-contained spray can such that a spray of fluid from the spray nozzle passes through the stream of ions and becomes electrostatically charged.</p> |
