The usage of Optiflo ink pumps, Norcross viscometers and Delpro chamber doctor blades, by Advanced Supplies (AS) to manage the ink control loop, is discussed. The technology used within the Optiflo range reduces air consumption and minimizes energy losses. Control is provided by the M50 viscometers, in which the M50 inline sensors forms an integral part of ink line. The Delpro chamber's compact design eliminates the need for large volumes of priming ink, and once commissioned requires no resetting or operator adjustment.
