WeatherExpert® Ultra High Efficiency, Variable-Speed Single-Packaged Rooftop Unit
48JC

Ultra 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 with variable speed cooling capacity control is just one of many technological advances that prove that not all rooftop units are created equal. Other enhancements include SystemVu™ controls and coil technology, variable speed compressor, indoor and outdoor fan motors, tool-less filter access doors and more.
