Preferred Series™ Puron Advance™ Single-Packaged Hybrid Heat Rooftop Unit

549Q

Hybrid Heat Rooftop with Axion™ Technology

Bryant's WeatherMaster® rooftops unit with Puron Advance™ and Axion™ Fan Technology offers an environmentally sustainable solution for a brighter future. The direct drive Axion™ 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. The 48QE offers a heat pump compression system with auxiliary gas heaters. All units come standard with stainless steel gas heat exchangers and controls. Units can operate as a heat pump, hybrid heat unit (gas and heat pump simultaneously) or as a gas heat unit when ambient temperatures dip below the low ambient cutoff.
