Heat Pump with Ecoblue™ Technology


3 to 25 Nominal Tons

Carrier’s WeatherMaker® rooftops (RTU) with Puron Advance™ (R-454B) and EcoBlue™ Fan Technology, offer an ecofriendly 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 WeatherMaker® 50FEQ 3 to 12.5 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.FeaturesPerformance Features
