Encore® HD Automatic Powder Spray Guns Allow Easy Adjustment
New Nordson Encore® HD Automatic Powder Spray Guns Allow Easy Adjustment of Powder Concentration and Spray Velocity to Achieve Optimum Coating Coverage and Cured Finish Quality. Achieve Better process control through an integrated coating solution, incorporating the Encore HD gun, the Nordson HDLV® dense phase pump and iControl® integrated control system.
AMHERST, OH, November 18, 2013 – Nordson Corporation (NASDAQ-NDSN), a leader in liquid and powder coating technologies, introduces Encore HD Automatic Powder Spray Gun – the third, and most advanced, generation dense-phase powder spray gun from Nordson. Encore HD guns incorporate a proprietary, integral HDLV module* that is designed to work with Nordson HDLV pump technology for superior spray versatility and performance. Nordson will be exhibiting the new Encore HD Automatic Powder Spray Gun at FABTECH 2013 in St. Louis, Booth #S5324.
Nordson HDLV – or “High Density Low Velocity” technology – delivers a high concentration of powder, but using very little air. An integrated coating solution, the system includes the Encore HD gun, the Nordson HDLV dense phase pump and iControl integrated control system to achieve the ultimate in process control.
“Using HDLV technology, the unique and innovative Encore HD gun design allows easy adjustment of the powder concentration and spray velocity to achieve optimum coating coverage and cured finish quality for every conceivable part type,” explains Bob Allsop, North American marketing manager for Nordson Powder Coating. “The gun can easily go from a highly dense phase spray to a more diluted (powder and air) mixture, and everywhere in between.”
Central to the system operation is the HDLV dense phase gun pump, which operates much differently than a traditional venturi pump. Venturi pumps use high velocity air, which – when coupled with abrasive powders and/or high powder output rates – causes them to wear over time. They also wear at different rates, requiring frequent adjustments to the gun settings to achieve consistent output.
The Nordson HDLV gun pump does not use a venturi throat, which means it does not wear out. As a result, powder output stays consistent over time. Additionally, the pump meters powder to the gun using less air to propel it – in fact, it is four times slower. This provides better charging as the aerodynamic forces are secondary to the electrostatic forces, producing a “softer” and more thoroughly charged powder cloud. The optimized electrostatic time provides better coverage into Faraday cage areas and improves overall transfer efficiency. In addition, in a traditional venturi powder pump, the atomizing air and the flow rate air interact, producing non-linear output. This is difficult to control and can lead to inconsistent results. Nordson HDLV technology removes the guesswork and variables in repeatability and uniformity, replacing it with simple, linear output control. This simplifies equipment set-up and adjustments.
