WeatherMaster® Single-Packaged Rooftop Units with EcoBlue™ Technology 48GC High Efficient Gas Heating : Electric Cooling 3 to 5 Nominal Tons

High Efficient Gas Heating / Electric Cooling

3 to 5 Nominal Tons

Exclusive, new EcoBlue™ Technology was designed to improve performance and efficiency while decreasing maintenance and installation costs. The industry’s first beltless direct-drive vane axial fan for rooftop units* is just one of many technological advances that prove that not all rooftop units are created equal. Other enhancements include a new control board and coil technology, permanently lubricated motor bearings, tool-less filter access doors and more – all available on this multiefficiency offering.
