MAXO-Z Setting new standards in energy efﬁciency and ease of operation
Water that stagnates in pipe sections with poor or no circulation poses a risk of legionella contamination. In commercially used buildings, increasingly high requirements are being set for pumps to ensure that drinking water is provided to a hygienic standard in the amounts and at the temperatures required. To ensure hygienically safe and consistently dependable drinking water circulation, Wilo has introduced a new efﬁcient drinking water pump called the Wilo-Yonos MAXO-Z. “The ErP Directive, which was rolled out a few years ago, set new standards for the efﬁciency requirements of pumps,” explains Derek Elton, Managing Director of Wilo Ireland. “We used the European requirements for pumps during the development stage of the Yonos MAXO-Z, despite it not being covered by the Directive. “With this glandless circulator, customers can beneﬁt from the advantages of high-efﬁciency technology, even in domestic hot water circulation. This makes a lot of sense, as domestic hot water circulators run up to 24 hours a day – for example in hospitals and hotels – and this high-efﬁciency technology can facilitate high energy savings compared to standard pumps.”

Thanks to its LED display, this glandless circulator for domestic hot water also provides complete transparency of the delivery head
and speed stages, as well as possible faults. To overcome pressure loss in the piping, the required/ calculated pressure can be set using the delivery head (dp-c). As a result, adjustment becomes more precise. Also new is the clear display of error codes. This means that any malfunction can be recognised immediately, which minimises the amount of service work required in the event of a fault. The Wilo-Connector and the pump’s compact design make the electrical connection easier and offer simpliﬁed and more ﬂexible on-site installation. Also, the cable is attached directly to the connector and only then plugged in to the pump. This creates enhancements both in operability and in ease of installation.
