Davis-Standard (Pawcatuck, CT) is showing a newly developed mid-range controller called the DS-eVUE at NPE2012 (Orlando, FL; April 1-5).

Features include a solid-state hard drive, a 15-inch (381mm) wide-screen HMI (human machine interface); a temperature auto-tuning option; an FDA-21 Part 11 ready for medical systems; and an optional wireless LAN connection. The hard drive has flexible mounting options

The new controller is available on Davis-Standard’s new direct drive medical (MEDD) extruder, which will also be shown at NPE2012. This compact extruder has a direct drive motor to improve energy efficiency. Advantages include linear movement, a replaceable feed section liner, and a Windows 7 PLC control system. The MEDD has interchangeable 1-inch (25mm) 24:1 L/D to ¾-inch (19mm) 24:1 L/D barrel assemblies for material versatility.

The new controller replaces the MESA III and its HMI systems. It may also be used by customers who had the Harrel Tubetrol controller. Davis-Standard said it will continue to service older controllers subject to availability, but the DS-eVUE will now be the standard mid-range option.

“As with the MESA, the DS-eVUE combines affordability with full process control for lines with one or two extruders,” said John Clemens, electrical engineering manager for Davis-Standard Extrusion Systems. “This system allows the operator to make set-point changes, monitor line status, create and download recipes, and conduct supervisory functions such as trending and reporting. The solid state hard drive and FDA-21 Part 11 upgrades are significant advantages with this new controller.”

The DS-eVUE uses the Microsoft Windows operating system with an anti-virus program, zip program and PLC interface program as needed, and SCADA (supervisory control and data acquisition) software. Davis-Standard offers customized applications program for controlling and monitoring the extrusion process.

In another improvement, Davis-Standard said that the DS-eVUE has an increased data tag count, enabling it to control larger systems than the MESA. Other features include a graphic overview, reports, trending, event log and data collection, a Web interface for two concurrent users, remote diagnostic capabilities, multi-level programmable security and e-mail notifications.

NPE2012 will be David-Standard’s first major show under a new ownership group. On Dec. 23, 2011, ONCAP, a mid-market private equity platform based in Toronto, acquired Davis-Standard, LLC from stockholders represented by Hamilton Robinson, LLC, including Davis-Standard management shareholders. ONCAP is part of Onex, which manages approximately $14 billion, of which $9 billion is third-party capital.
