The Grundfos Alpha1 electronic circulator features an electronically commutated motor and is designed to circulate water in heating and air conditioning systems. It offers three control modes: constant pressure, proportional pressure, and constant curve, each with three speed settings.
The Grundfos GO app and operating panel make it easy to copy curves and replace older integrated or standalone circulators. It features automatic air venting, dry-running protection, and a start-up function that helps prevent blockages caused by dirt, magnetite, and limescale. The ceramic shaft and bearings reduce wear, while the error codes on the operating panel make troubleshooting easier.
