Powder coatings applications technology sets precedent

Nordson developes a completely new and unique HDLV pumping and spray gun technology to attain the full benefit potential of dense phase powder coatings Prodigy System.

The Nordson Prodigy* powder coatings product line epitomizes dense phase application technology for consistently superior performance and fast color change speed.

Dense phase powder transport and application technology, for which Nordson trademarked the acronym HDLV* (High-Density powder, Low-Velocity air) with its introduction of the original Prodigy System last year, set a precedent for coatings
performance and efficiency. This revolutionary method of delivering powder from a storage/conditioning device (conventional fluidized hopper or locally fluidized vibratory box feeder) to a manual or automatic spray gun, uses "High-Density" powder flow and "Low-Velocity" conveyance air.

The Prodigy Color-on-Demand* instant color selector with HDLV (high-density powder, low-velocity air) technology is all about ultra-fast color changes – in less than 20 seconds – for more color changes per shift and higher productivity.

In a bulk powder transfer application, dense phase technology dramaticall reduces the amount of conveyance air required, eliminating the challenges in dealing with excessive compressed air in a conventional system. In a gun pump application, conveyance air is also dramatically reduced, producing a very low-velocity, highly dense with powder, spray pattern from the gun, for a multitude of coating performance and operational benefits.

Prodigy Color-on Demand features a touch-screen color display with user configurable buttons that are easily set for size and color identification at the touch of a button. This means more color changes per shift and higher throughput to meet lean manufacturing requirements. See photo at right.

Faster application capability, more complete coating coverage, and higher transfer efficiency to name just a few. Some companies developed just the pumping portion of dense-phase technology, and adapted it to conventional spray guns. However, the Industrial Coatings Systems division of Nordson Corporation developed completely new and unique HDLV pumping and spray gun technology to attain full benefit potential of dense phase powder coatings.

Nordson utilized that technology for its truly unique Color-On-Demand instant color selector, quick-color change manifold and control system for changing powder colors, automatically, in less than 20 seconds, and with no color contamination.

Combined with the ALL NEW Prodigy Generation II manual gun system, Prodigy Color-on-Demand gives you an integrated solution for precision dispensing and ultra-fast contamination free color change. See photo at left.

Now released, second-generation Nordson Prodigy HDLV technology surpasses anything else on the market. While the original Prodigy HDLV dense phase technology set the bar higher for coating speed and transfer efficiency, making the painter's job easier, and with more consistent and repeatable results, Prodigy Generation II further increases performance, durability and wear life.

The Prodigy Generation II manual spray gun, now nearly 20 percent lighter, is easier to use, and takes consistent, repeatable performance to an even higher level. The Prodigy HDLV automatic gun brings all the benefits of the manual version, for even more consistent and repeatable performance in applications more-well-suited to automatic powder coatings operation.
