WeatherExpert® Puron Advance™ Single-Packaged Rooftop Units with EcoBlue™ Technology
48WE

Gas Heating / Electric Cooling

6 to 15 Nominal Tons – High Outdoor Air Capable

Carrier’s 48WE WeatherExpert® rooftops (RTU) with Puron Advance™ (R-454B) and EcoBlue™ Fan Technology, offer an environmentally sustainable solution for a brighter future. With a GWP of 466 and similar performance to R-410A, Puron Advance easily exceeds the EPA's new, stringent, <700 GWP refrigerant requirement. Our direct drive EcoBlue™ indoor fan system uses a Vane Axial fan and electronically commutated motor and all 48WE models are designed and configured for expanded envelope operation. 48WE models can operate as a single zone AC, multizone VAV unit, or with up to 100% outdoor air for ventilation or make-up air. All units include new options that enable 100% outdoor air operation including modulating low load protection valve to prevent refrigerant circuit issues, a double wall construction option, modulating hot gas reheat for dehumidification with supply air temperature control, and a 5:1 turndown modulating gas heat valve for a wide operating range. All units include Carrier SmartVu™ controls for control flexibility, ease of setup and commissioning, and simplified troubleshooting.
