Head start in the future: the Wilo-Stratos MAXO family.
The world’s first smart-pump* features tomorrow’s innovations that make your life easier today: The Wilo-Stratos MAXO offers you greater efficiency, connectivity and comfort than ever before. It is the first pump which has an intuitive user interface – and makes installation and operation as easier than ever before. The Wilo-Stratos MAXO also redefines system efficiency: By featuring innovative energy-saving functions and new control modes it attains maximum system efficiency.
The highest level of compatibility with existing systems is also a matter of course for our smart-pump.In 2017, the Wilo-Stratos MAXO has already been awarded the “Design Plus powered by ISH” seal of approval for its sustainability, innovative design and energy-efficient technology.
In addition, the Wilo-Stratos MAXO has won “GOLD” in the “Technology” category of the “BLUE INNOVATION AWARD 2018” exhibitor’s innovation prize, which was awarded for the first time at the expoEnergy 2018 in Wels. Put your faith in the pump technology of the future; you and your customers will profit from the outstanding features of the Wilo-Stratos MAXO.
* We understand a smart-pump as a new category of pumps, which goes far beyond our high-efficiency pumps or pumps with pump intelligence. Only the combination of the latest sensor technology and innovative control functions (e.g. Dynamic Adapt plus and Multi-Flow Adaptation), bidirectional connectivity (e.g. Bluetooth, integrated analogue inputs, binary inputs and outputs, Wilo Net interface), software updates and excellent usability (e.g. thanks to the Setup Guide, the preview principle for predictive navigation and the tried and tested Green Button Technology) make this pump a smart-pump.
Highest efficiency for heating, air conditioning and cooling.
Powerful, easy maintenance, reliable and a long service life are properties which you can naturally expect from Wilo pumps. Our high-efficiency pumps deliver top-rate performances for applications in heating, air conditioning and cooling.
Supplying a property with water and heat at all times puts high demands on the pumps with regard to energy efficiency and resource conservation. Wilo meets these challenges with customised solutions and highly efficient technology; our heating systems achieve maximum efficiencies. This way, landlords and business owners can noticeably lower their operating costs and increase the value of their property long-term.
Innovative technologies for more efficient systems.
The new intelligent control modes are in Focus for higher efficiency. The Wilo-Stratos MAXO is the pump with the highest system efficiency on the market. It achieves its maximum efficiency thanks to optimised and innovative energy-saving functions such as Multi-Flow Adaptation and No-Flow Stop as well as its very good EEI ≤ 0.17 to ≤ 0.19. The combination of additional sophisticated control functions such as Dynamic Adapt plus allows for highest energy efficiency of the Wilo-Stratos MAXO – with easiest operation.
No-flow stop
The energy-saving function automatically deactivates the pump at zero-flow-detection. The Wilo-Stratos MAXO recognises when, despite its speed, the volume flow supplied is too low. This means that the valves in the consumer circuit are closed. Thanks to the intelligent function the pump stops the motor if the volume flow falls below a specified minimum level. At regular intervals, it checks whether the minimum volume flow has been exceeded again, then continues in its set control mode in auto control mode. The Wilo-Stratos MAXO thus avoids unnecessary running time and saves electrical pumping energy.
