QSI Touch Screen Terminal Improves Temperature and Compressor Control for American Red Cross Blood and Plasma Storage Rooms.

SALT LAKE CITY, UTAH. November 2005. QSI Corporation, manufacturer of rugged operator interface and mobile data terminals, was selected by Pro Refrigeration Inc., developers of chilling systems, to provide the graphic human machine interface (HMI) on an advanced microprocessor driven refrigeration controller. This technology was recently implemented at the newest American Red Cross facility to improve temperature and compressor control for their blood and plasma storage rooms. This new state-of-the-art facility in Pomona, California, is the largest blood bank in the United States.

After only operating a year, the Red Cross realized their existing control system was not adequate for controlling the temperature of their blood and plasma storage rooms. With blood and plasma worth millions of dollars stored in each room, variance in room or product temperature is not acceptable. Strict quality standards require little or no temperature fluctuation of the blood and plasma, at a holding temperature of -32 °C.

The project involved the installation of Pro Refrigeration's CR110 Controllers onto existing Red Cross condensing units, with QSI Corporation's QTERM-G70 touch screen operator interface mounted outside the storage room for storage room control. The QTERM-G70 operator interface was easily customized for this application. The results included much better storage room temperature control, more effective defrost cycles, improved data logging ability and overall improved system control.



QSI's QTERM-G70 is a rugged, Ethernet-enabled graphic human-machine terminal using a touch screen to interface with the user. This rugged terminal features a robust list of industrial-grade hardware features and options including a 320x240 lighted graphic LCD display (color or grayscale); 100Base-T Ethernet with TCP/IP support; touch screen with optional PS/2 keyboard connection; and an EIA-232, -422 or -485 serial interface. The QTERM-G70 graphic terminal is ruggedized for use in harsh industrial environments and is NEMA-4 rated and CE certified.

The QTERM-G70 uses an object-based graphic terminal programming language called Qlarity™ (pronounced Clarity). Designing a simple control panel interface or a complete stand-alone application has never been easier. The ability to use pre-defined objects, edit existing objects or author your own objects, provides flexibility to the novice and expert alike. Qlarity Foundry™, a PC-based design tool, provides a Windows® environment for screen creation, application simulation, debugging and downloading to the QTERM-G70 terminal."

"We are pleased to have worked with Pro Refrigeration on such an important project for the American Red Cross," said Jim Elwell, President of QSI. "It is rewarding to know QSI's products are a part of a solution to properly store precious blood and plasma used in hospitals to save lives."

"We are honored to have worked on this challenging and successful project with American Red Cross," said John Butorac, Controls Specialist for Pro Refrigeration, Inc. "With the QTERM-G70 and the CR110, we were able to successfully eliminate many components of the existing system, while delivering a completely redundant control system."
