High efficiency

The Wilo Stratos high-efficiency circulator powered by EC motor technology delivers up to 285 USGPM while reducing energy consumption up to 80%. A specially designed impeller lowers friction loss. A slotted tube made of composite material prevents eddy-current loss. A unique rotor adds to the low energy design. Operation is simple: a “green button” controls all essential functions. A front mounted display makes reading operational data accessible and easy. Wilo’s IR-monitor allows remote control operation and can quickly read data like hours and load diagrams from 30 ft away, helping maintain efficient operation. The Wilo Stratos can also be customized for professional building management requirements. It is the first electronically controlled wet-rotor circulator for heating that is also designed to avoid condensate, making it available as part of a cooling water systems for air conditioning and industrial refrigeration. The Wilo Stratos provides built-in value-added, versatility and efficient engineering design.
