In pure water systems, the correct dimensioning of the distribution system and the pump ensures that all consumers receive sufficient quantities of the medium. Problems can occur if too many points-of-use valves are opened simultaneously, resulting in a partial vacuum in the system. If air enters the system, operation in accordance with the GMP guidelines can no longer be ensured.
Christ's newly developed software, Liprocontrol, enables comprehensive management of the points-of-use. This program permits the control and documentation of all accesses to the distribution system and thus a complete audit trail. In addition, it allows the current operating status of the water treatment system and of the process systems to be displayed graphically at any time.
The software can, for example, be integrated into a compact media column made of stainless steel, together with the necessary T-valves to permit the consumption of, for example, Purified Water (PW) and the extraction of samples in accordance with the GMP guidelines. Various special versions are available, depending on the application (distribution of PW, HPW or WFI) and the temperature range (25, 45, 80 °C or pure steam). The touch panel permits preselection of the amount of medium to be drawn and of the desired temperature.
At the same time, it shows a graphical display of the complete system, permitting the timely detection of trends. Liprocontrol can be linked to a higher level control system, such as WinCC, and thus controls the availability of the points-of-use and records all related data.
The documentation complies with 21 CFR Part 11 and permits integrated password protection. The panel can also be equipped with a recorder function. By default, the user interface is available in German or English. Optionally, the functionality of 21 CFR Part 11 can be integrated into the panel.
The point-of-use management system improves the safety of the entire system and simplifies its vali-dation. The media column with the Liprocontrol soft-ware can, if desired, be delivered standardised and prequalified.
