48LC WeatherExpert® rooftop units were designed by customers for customers. They are Carrier’s most efficient commercial packaged rooftop ever produced and have some of the industry’s highest IEER’s available. The multi stage cooling compressor logic allows for added comfort, energy savings and humidity control. The unit is ideal for single zone variable air volume capability. Units are pre-wired and pre-charged with environmentally sound Puron® (R-410A) refrigerant at the factory. The units are factory tested in both heating and cooling modes.
Exceeded Department of Energy Advanced RTU Challenge by 15%

3 to 5 ton models have two-stage cooling capacity control and 6 to 23 ton models have three-stage cooling capacity control
Up to 17.5 SEER and 20.8 IEER
Exclusive non-corrosive composite condensate pan in accordance with ASHRAE 62 Standard, sloping design; side or center drain
3 to 23 ton models have standard cooling operation up to 125 °F (52°C), and down to 10°F (-12°C) (3-5 ton models), or down to 40°F (4°C) (6-23 ton models). 3 to 5 ton models have cooling operation down to 0°F (-18°C) with ComfortLink controls.
VAV models use a duct static pressure sensor to vary the units indoor fan motor variable frequency drive (VFD) while cooling capacity is controlled by the units supply air temperature sensor, to make sure the correct temperature in each zone.
