    Wilo-Stratos D High Efficiency Circulator


    Up to 80% Energy Savings!*

    Energy is a valuable commodity. This is why Wilo created the world’s first high-efficiency circulator in 2001. With the help of ECM technology, this efficient, functional and flexible pump for heating, cooling, and air conditioning reduces annual power consumption by up to 80%. Standing for Electronically Commutated Motor, ECM essentially comprises a synchronous motor with a permanent magnet rotor. The unique rotor-stator construction helps eliminate electrical losses.
