Preferred Line Puron Advance™ Single-Packaged Rooftops Units with Axion™ Technology
Preferred Line Puron Advance™ Single-Packaged Rooftops Units with Axion™ Technology 549L
Heat Pump with Axion™ Technology 3 to 25 Nominal Tons
Bryant’s Preferred Line™ rooftops (RTU) with Puron Advance™ (R-454B) and Axion™ 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 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. Our Preferred Line™ 549L units are designed to be a direct replacement for many existing rooftops. That makes replacements fast and easy, eliminating the need for curb adapters or different utility connections.
