Superior intelligence, unparalleled quality.

The Wilo-Stratos MAXO-Z has specifically been developed for drinking water applications and combines the innovative characteristics of the Wilo-Stratos MAXO with a stainless steel housing. The durable and hygienic material sets it apart from other domestic hot water circulators on the market.



Your advantages

  • Intuitive operation by application-guided settings with the setting assistant plus the combination of a new display and operating button using Green Button Technology.
  • Highest standard of drinking water hygiene and energy efficiency with the new, innovative, intelligent T-const. control function.
  • Optimum hygiene promotion through thermal disinfection detection.
  • State-of-the-art communication interfaces (e.g. Bluetooth) for connection to mobile devices, including direct pump networking for multi-pump control via the Wilo Net.
  • Maximum convenience for electric installation with the spacious and clearly arranged terminal room and optimised Wilo-Connector.
