Wilo Pumps

Pumps and pump systems for heating, cooling, pressure boosting and water supply for commercial buildings.

Wilo ECM Technology Delivers Energy Savings

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

The Stratos GIGA, multiple models of Wilo Stratos and Stratos Z circulators are energy-efficient and feature “red button” technology, LED displays, and control modules that enable integration with building management systems.

Stratos, Stratos D and Stratos Z high-efficiency ECM circulators have a standard warranty of 4 Years.
