Your advantages
Wilo-Stratos MAXO

The smart-pump for commercial buildings with building management system.

With optimised and innovative energy-saving features, the Wilo-Stratos MAXO sets new standards for commercial HVAC and drinking water applications in terms of energy efficiency. Its outstanding user-friendliness makes operating the pump easier than ever before.



Your advantages

  • Various options for integration into the building management system
  • Intuitive operation through application-guided settings using the setting assistant combined with a new display and operating button with Green Button Technology.
  • Maximum energy efficiency thanks to the combination of optimised and innovative energy-saving functions (e.g. No-Flow Stop).
  • Optimum system efficiency thanks to new and innovative intelligent control functions such as Dynamic Adapt plus, Multi-Flow Adaptation, T-const. and ΔT-const.
  • 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 during electrical installation thanks to the clear and spacious terminal room and the optimised Wilo-Connector.
