Weather Series Rooftop Units (RTUs) with EcoBlue Technology

EcoBlue™ Technology in select models of WeatherMaker® and WeatherMaster® rooftop units. It was designed to improve performance and efficiency while decreasing maintenance and installation costs. By streamlining the design, eliminating belts, pulleys, bearings and the shaft, the Weather Series Rooftop Units (RTUs) with EcoBlue Technology from Carrier offer up to 40 percent more efficiency than some other rooftop units. 

Most notable of its many features is the exclusive beltless direct-drive vane axial fan system—an industry first for rooftop units. This patent-pending technology replaces traditional belts and pulleys with a simpler, more compact design, all with 75 percent fewer moving parts.

The outdoor fan system’s high-density composite blade fan is also an exclusive design. Other technological advances that differentiate these units include: a new control board and coil technology, increased factory options and a tool-less filter access door.
