Industrial Finishing Systems has been at the pinnacle of powder
application technology with its unique charging system "Total
Energy Control", which gives automatic control of both current
and voltage. Developed by our own R & D department, "TEC"
has revolutionized the way we electrostatically apply powder;
the benefits are numerous and significant. After four years in
production, we believe it's time to recall exactly why our application
equipment incorporating "TEC" continues to lead the
field in powder coating technology ... worldwide!
is used to automatically control the discharge energy of the
spray gun depending upon the distance to earth of the gun nozzle,
up to a maximum of 85 kV and 50 µA. The maximum current
generated is limited to 50 µA, but the current and voltage
are reduced automatically as the gun approaches the product.
Rather than controlling just the current or the voltage, the
operator is able to control energy output from the gun.
air, away from the influence of any earthed objects the maximum
discharge current will be approximately 20 µA when the
discharge potential is set to maximum 85 kV. As the gun is moved
from within one metre of the product, to current starts to rise
progressively until a threshold of approximately 50 µA
is reached. This will normally be at approximately 250 - 300
mm from the product. If the gun is than moved still closer to
the product, the discharge current and voltage will progressively
reduce, thus preventing overcharging of the power cloud or product
surface when the gun is in close proximity to the product. This
function is automatically reversible, the discharge current and
voltage increasing as the gun is then moved away from the earthed
object. This ability to control the output energy of the gun
allows the operator to take the gun right in to corners and recesses,
and still effectively charge powder at very low electrostatic
outputs. High film builds are achieved with superior finishes
and no surface disruption, whilst very significant improvements
are noted in the ability to re-coat previously coated products.
