To drive or not to drive? That is the question: whether it’s smarter to suffer pressure transients, or to install ABB ACQ580 drives with PID control, and, by their utilisation, maintain system pressure, avoid pump switching transients and stop the over pressuring of your system.
An EDC built panel comprising two ABB 1.1kW IP55 drives will replace two DOL driven pumps on a water site (shown inset). The new panel will facilitate automatic duty/ rotation and fail-over and will maintain system pressure at 4.5 bar (reducing it from 5.4 bar at present). Cool (and smooth) running with ABB drives and EDC panel builds.
