WeatherMaster® Puron Advance™ Single-Packaged Rooftop Units with EcoBlue™ Technology
50GE

Electric Heat / Electric Cooling

3 to 25 Nominal Tons

Carrier’s WeatherMaster® 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. The benefit is clear: when compared to legacy belt drive systems, this Vane Axial design has 75% fewer moving parts, uses up to 40% less energy, and has no belts, blower bearings, or shaft. Our WeatherMaster® 48/50GE 3 to 25 ton units are specifically designed to fit on Carrier roof curbs installed as far back as 1989. That makes replacements fast and easy, eliminating the need for curb adapters or different utility connections.
