Standard high-efficiency pump for domestic hot water circulation in large buildings.
The Wilo-Yonos MAXO-Z is a high-efficiency circulation pump designed to provide hygienic domestic hot water in rental properties, administrative buildings, and commercial real estate. It features an LED display that allows users to intuitively monitor status indicators such as delivery head, speed stage, and fault codes. Its compact design and the included Wilo electrical connection plug simplify installation, while "Green Button Technology" makes operation exceptionally easy.
